Handrails, stanchions, fittings and deck equipment lose their shine within a few weeks at sea, and the crew or the port technical service has to bring them back without taking the ship out of service. That job belongs to <strong style=\"color:#111;font-weight:800;\">polishing discs for the maritime sector<\/strong>, almost always with the part in place and between two port calls.<\/p>\n<p style=\"margin:0 0 18px;\">Polishing at sea has little in common with polishing in a workshop. The tube is welded to the deck and cannot be turned, there is teak and paint all around, passengers may be a few metres away and stainless and brass share the same storeroom. The shine also has a job to do: a closed surface holds less salt and stains later.<\/p>\n<p style=\"margin:0 0 18px;\">Getting it wrong costs time and appearance: polishing over a pit stains again in the same spot, and a felt shared with brass covers a freshly finished tube in rust. Below you will find the criteria we apply and the mistakes we see most often.<\/p>\n<p style=\"margin:0 0 22px;\">This guide covers polishing and buffing on vessels in service, in port and offshore.

Starting condition: surface salt staining or real pitting<\/h3>\n<p style=\"margin:0 0 16px;\">Almost all polishing on board starts with a complaint about appearance: the promenade deck handrail has turned brown, the stanchions have reddish spots or a stainless cover has lost its shine. In most cases it is surface corrosion caused by chlorides, the brown staining known in the stainless industry as <strong style=\"color:#111;font-weight:800;\">\u201ctea staining\u201d<\/strong>, and it can be recovered with a properly done polish.<\/p>\n<p style=\"margin:0 0 16px;\">Before fitting the felt, run your fingernail over it and look under raking light. If there is <strong style=\"color:#111;font-weight:800;\">pitting<\/strong> with depth, polishing makes it shiny but does not remove it. That case needs a pass with flap discs first and then polishing; with surface staining you can start straight at the intermediate step.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">2. Original finish and grain direction to be respected<\/h3>\n<p style=\"margin:0 0 16px;\">Handrails and fittings in passenger areas are usually <strong style=\"color:#111;font-weight:800;\">mirror polished<\/strong>, while bulkheads and galley equipment are usually satin finished with a directional grain. Mirror polishing one section of a satin item, or satin finishing in another direction, leaves a patch that can be seen from far away.<\/p>\n<p style=\"margin:0 0 16px;\">On tube, the satin grain almost always runs along the tube, and polishing has to follow that direction to the ends of the section, not stop halfway. Agree the finish with the shipowner before starting, on a sample section.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">3. Stainless, chlorides and why a closed surface lasts longer<\/h3>\n<p style=\"margin:0 0 16px;\">Different grades of stainless sit side by side on deck, and not all of what is fitted is meant to be exposed to salt. Polishing does not change the alloy: a low-alloy stainless will keep staining before one with molybdenum, however well polished it is. What it does change is the <strong style=\"color:#111;font-weight:800;\">roughness<\/strong>: a closed surface without deep scratches holds less salt and moisture, and stains later.<\/p>\n<p style=\"margin:0 0 16px;\">That is why, in a marine environment, it is not advisable to stop at a coarse satin finish when the item should be polished. Each grit step removes the scratches of the previous one; if one is skipped, grooves remain where salt builds up. Our guide to <a style=\"color:#cc0000;font-weight:700;text-decoration:underline;text-underline-offset:3px;\" href=\"https:\/\/www.abrasteel.com\/en\/blog\/finishing-and-polishing\/types-of-finishes-when-working-with-stainless-steel-surfaces\/\">stainless steel finishes<\/a> explains what each one offers.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">4. Polishing in place or taking the part to the port workshop<\/h3>\n<p style=\"margin:0 0 16px;\">A fifty-metre handrail or a stanchion welded to the deck is polished where it is, with a <strong style=\"color:#111;font-weight:800;\">random orbital sander<\/strong> or a variable-speed grinder and hook-and-loop backed discs, which let you move through the grits without changing the pad. The operator works on their knees or leaning over the rail.<\/p>\n<p style=\"margin:0 0 16px;\">Small parts that can be removed, such as cleats, fittings, inspection covers or porthole rings, are done far more efficiently in the port workshop, on a bench polisher with <strong style=\"color:#111;font-weight:800;\">rope and cotton discs<\/strong> and compound. The shine comes out more even and there is no compound on the deck.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">5. Compound and residue on the part and its surroundings<\/h3>\n<p style=\"margin:0 0 16px;\">On deck, polishing never happens in a vacuum: around it there is teak, non-slip paint and, on passenger vessels, outdoor furniture. <strong style=\"color:#111;font-weight:800;\">Greasy compound<\/strong> gives a deep shine but spatters and leaves a film; dry compound makes less mess. Protecting the area around the stanchion with tape and plastic saves hours of cleaning the teak, which absorbs the grease and stays stained.<\/p>\n<p style=\"margin:0 0 16px;\">Compound residue on the stainless itself also counts. A greasy film left on the tube traps salt and dust and brings the next stain forward. When you finish, clean the part until no compound remains, and a product such as the anti-fingerprint also leaves a thin protective film.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">6. Separate finishing material for stainless, brass and bronze<\/h3>\n<p style=\"margin:0 0 16px;\">On board it is not just stainless that gets polished. Portholes, bells, plates, taps and old fittings are often <strong style=\"color:#111;font-weight:800;\">brass or bronze<\/strong>, and it is tempting to use the same felt for everything. A felt or cotton wheel that has worked brass or steel carries particles and compound residue that then become embedded in the stainless, and in a salty environment that turns into rust stains.<\/p>\n<p style=\"margin:0 0 16px;\">We recommend dedicated finishing material for each metal, stored separately in the storeroom. On anodised aluminium on the superstructure, do not polish without asking first: the abrasive removes the anodic layer, which is what protects the aluminium.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">7. Maintenance between port calls: scheduled polishing or non-abrasive restoration<\/h3>\n<p style=\"margin:0 0 16px;\">Not every loss of shine calls for an abrasive. A light stain a few weeks old can often be removed with a metal restorer, which acts on surface rust while respecting the original polished or satin finish, without removing material and without a machine. It is a job the crew can do at sea.<\/p>\n<p style=\"margin:0 0 16px;\">The disc is kept for staining that will not shift, repaired sections and the seasonal overhaul. Separating the two tasks extends the life of the stainless, because every polish removes some material.<\/p>\n<h2 id=\"aplicaciones-pulir-maritimo\" style=\"margin:clamp(38px,9vw,54px) 0 18px;padding-bottom:10px;border-bottom:2px solid #e8ebef;color:#023a51;font-size:clamp(24px,6vw,30px);line-height:1.18;font-weight:700;\">Applications and technical table for polishing on board and in port<\/h2>\n<p style=\"margin:0 0 16px;\">With <strong style=\"color:#111;font-weight:800;\">polishing discs for the maritime sector<\/strong> it makes sense to organise the decision by part and by where the work is done, because the same stainless is polished differently on a handrail welded to the deck, on a removed fitting or in a ship&#8217;s galley.<\/p>\n<p style=\"margin:0 0 16px;\">The table sums up the most common polishing situations with the vessel in service and at port and offshore installations, with the constraint that governs each one and the finishing criterion we recommend.<\/p>\n<div style=\"overflow-x:auto;margin:24px 0;border:1px solid #e8ebef;\">\n<table style=\"width:100%;min-width:720px;border-collapse:collapse;background:#fff;\">\n<thead>\n<tr>\n<th style=\"padding:14px;background:#023a51;color:#fff;text-align:left;font-weight:800;border-bottom:1px solid #e8ebef;\">Part and situation<\/th>\n<th style=\"padding:14px;background:#023a51;color:#fff;text-align:left;font-weight:800;border-bottom:1px solid #e8ebef;\">Main constraint<\/th>\n<th style=\"padding:14px;background:#023a51;color:#fff;text-align:left;font-weight:800;border-bottom:1px solid #e8ebef;\">Finishing criterion<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Stainless handrails and stanchions on passenger decks<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Fixed part, long sections and passengers nearby.<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Random orbital with hook-and-loop, grits in sequence and the same direction along the whole section.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Removable cleats and fittings<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Small parts with curved shapes.<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Bench polisher in the port workshop, with rope disc and compound.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Brass or bronze portholes and taps<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Risk of contaminating stainless with the same material.<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Dedicated cotton wheel and compound, stored separately.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Ship&#8217;s galley and provision store<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Directional satin finish and hygienic cleaning.<\/td>\n<td style=\"padding:14px;border-bottom:1px solid #e8ebef;vertical-align:top;\">Satin finish in the original direction and a surface without deep scratches.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:14px;vertical-align:top;\">Pontoon railings and boarding gangways<\/td>\n<td style=\"padding:14px;vertical-align:top;\">Continuous exposure to sea spray.<\/td>\n<td style=\"padding:14px;vertical-align:top;\">Closed finish and scheduled maintenance with restorer.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">Deck stainless with the vessel operating and passengers on board<\/h3>\n<p style=\"margin:0 0 16px;\">On ferries and cruise ships, handrail polishing is fitted into hours when there are no passengers on deck or is cordoned off section by section. The work is done with a random orbital: an intermediate step with a fine-grit hook-and-loop disc to remove the stain and the scratches, and a finish with felt and compound. On sections with a repair weld, the prior dressing with flap discs is covered in <a style=\"color:#cc0000;font-weight:700;text-decoration:underline;text-underline-offset:3px;\" href=\"https:\/\/www.abrasteel.com\/en\/blog\/abrasive-discs\/flap-discs-maritime\/\">flap discs for the maritime sector<\/a>.<\/p>\n<p style=\"margin:0 0 16px;\">On thin-walled tube, pressure is the enemy: it heats the tube, leaves a bluish tint and wears out the felt.

With a rope disc, a stitched cotton wheel and compound, a stainless cleat or fitting gets its shine back in minutes, and the brass of a porthole is done with its own disc.

There, a full polish is done once and then maintained with cleaning and restorer, because polishing thoroughly every few months uses up material and time.<\/p>\n<p style=\"margin:0 0 16px;\">If the stainless has been welded during the repair, the weld needs pickling before the final polish.

If the tube has pits or an undressed weld, polishing makes it shiny for a season and the stain comes back in the same place.<\/p>\n<p style=\"margin:0 0 16px;\">The second is polishing on board as if in a workshop, without thinking about the teak, the passengers or a storeroom where the finishing material ends up mixed.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">Bringing up a shine over a pit with depth<\/h3>\n<p style=\"margin:0 0 16px;\">The rim of the crater ends up shiny and the bottom still holds rust and salt. If your fingernail catches, the area needs dressing before polishing.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">Leaving greasy compound on the stainless and the teak<\/h3>\n<p style=\"margin:0 0 16px;\">The compound film traps salt and brings the next stain forward, and what drops onto the teak darkens it. Clean the tube until no compound remains and protect the wood before you start.<\/p>\n<h3 style=\"margin:26px 0 8px;color:#023a51;font-size:clamp(20px,5.2vw,22px);line-height:1.25;font-weight:800;\">Changing the polishing direction halfway along a section<\/h3>\n<p style=\"margin:0 0 16px;\">A change of direction or an abrupt stop halfway along the handrail can be seen against the light from all over the deck.

This one deals with the final step on stainless and other exposed metals: removing the salt stain, evening out the finish and bringing up the shine.<\/p>\n<\/div>\n<\/details>\n<details style=\"border-bottom:1px solid #e8ebef;background:#ffffff;\">\n<summary style=\"cursor:pointer;list-style-position:outside;padding:16px 0;color:#023a51;font-size:clamp(18px,4.8vw,21px);line-height:1.25;font-weight:800;\">How do you remove the brown staining from a ship&#8217;s stainless handrails?<\/summary>\n<div style=\"padding:0 0 16px;color:#232323;\">\n<p style=\"margin:0;\">If it is superficial, with an intermediate step using a fine-grit hook-and-loop disc and a finish with felt and compound, along the tube. If it is recent, a non-abrasive restorer is often enough; if there is pitting, dress it first.<\/p>\n<\/div>\n<\/details>\n<details style=\"border-bottom:1px solid #e8ebef;background:#ffffff;\">\n<summary style=\"cursor:pointer;list-style-position:outside;padding:16px 0;color:#023a51;font-size:clamp(18px,4.8vw,21px);line-height:1.25;font-weight:800;\">Can a stanchion be polished without removing it?<\/summary>\n<div style=\"padding:0 0 16px;color:#232323;\">\n<p style=\"margin:0;\">Yes, with a random orbital and hook-and-loop backed discs, which let you move through the grits without changing the pad. Protect the surrounding teak and work with light pressure.<\/p>\n<\/div>\n<\/details>\n<details style=\"border-bottom:1px solid #e8ebef;background:#ffffff;\">\n<summary style=\"cursor:pointer;list-style-position:outside;padding:16px 0;color:#023a51;font-size:clamp(18px,4.8vw,21px);line-height:1.25;font-weight:800;\">Which compound is best for polishing stainless on deck?<\/summary>\n<div style=\"padding:0 0 16px;color:#232323;\">\n<p style=\"margin:0;\">Greasy compound gives a deeper shine but spatters and leaves a film; dry compound makes less mess. On deck, with teak or passengers nearby, dry compound or a very measured application of the greasy one usually pays off, and the tube should be cleaned when you finish so that it does not trap salt.<\/p>\n<\/div>\n<\/details>\n<details style=\"border-bottom:1px solid #e8ebef;background:#ffffff;\">\n<summary style=\"cursor:pointer;list-style-position:outside;padding:16px 0;color:#023a51;font-size:clamp(18px,4.8vw,21px);line-height:1.25;font-weight:800;\">Can I use the same felt for the brass of the portholes and for stainless?<\/summary>\n<div style=\"padding:0 0 16px;color:#232323;\">\n<p style=\"margin:0;\">It is not advisable. The felt holds particles and compound residue that transfer to the stainless on the last pass, and with the salty humidity they show up as rust spots. It is best to have dedicated finishing material for each metal, stored separately.<\/p>\n<\/div>\n<\/details>\n<details style=\"border-bottom:1px solid #e8ebef;background:#ffffff;\">\n<summary style=\"cursor:pointer;list-style-position:outside;padding:16px 0;color:#023a51;font-size:clamp(18px,4.8vw,21px);line-height:1.25;font-weight:800;\">How often should the stainless on a passenger vessel be polished?<\/summary>\n<div style=\"padding:0 0 16px;color:#232323;\">\n<p style=\"margin:0;\">There is no fixed figure: it depends on exposure and on the stainless. What works is separating tasks: frequent cleaning and restorer by the crew, and disc polishing only when the stain will not shift or before an overhaul.<\/p>\n<\/div>\n<\/details><\/div>\n<div data-abrasteel-sticky-cta=\"true\" aria-label=\"Abrasteel quick actions\" style=\"position:fixed;right:max(12px,env(safe-area-inset-right));bottom:max(12px,env(safe-area-inset-bottom));z-index:9999;width:min(260px,calc(100vw - 24px));max-height:calc(54vh - 24px);background:#ffffff;border:1px solid rgba(2,58,81,.16);box-shadow:0 18px 44px rgba(2,58,81,.20);overflow:auto;\">\n<div style=\"height:6px;background:linear-gradient(90deg,#cc0000 0%,#cc0000 38%,#023a51 38%,#023a51 100%);\"><\/div>\n<p><button type=\"button\" aria-label=\"Close notice\" onclick=\"this.closest('[data-abrasteel-sticky-cta]').style.display='none';\" style=\"position:absolute;top:10px;right:10px;z-index:2;width:32px;height:32px;border:1px solid #e8ebef;background:#ffffff;color:#023a51;font-size:18px;line-height:1;font-weight:800;cursor:pointer;\">x<\/button><\/p>\n<div style=\"padding:clamp(12px,3.5vw,16px) clamp(12px,3.5vw,16px) clamp(10px,3vw,14px);\">\n<p style=\"margin:0 0 6px;color:#cc0000;font-size:13px;font-weight:800;letter-spacing:.06em;text-transform:uppercase;\">Abrasteel advice<\/p>\n<p style=\"margin:0 0 8px;color:#023a51;font-size:clamp(18px,4.8vw,20px);line-height:1.18;font-weight:800;\">Maintaining stainless on a ship or in a port?<\/p>\n<p style=\"margin:0 0 12px;color:#555f66;font-size:clamp(14px,4vw,16px);line-height:1.45;\">We help you define the polishing sequence and the finishing storeroom.<\/p>\n<\/div>\n<p><a style=\"display:block;padding:clamp(11px,3.2vw,13px) 14px;background:#cc0000;color:#fff;font-size:clamp(14px,3.8vw,15px);font-weight:800;text-align:center;text-decoration:none;\" href=\"https:\/\/www.abrasteel.com\/en\/contact\/\">Ask for technical help<\/a><a style=\"display:block;padding:clamp(11px,3.2vw,13px) 14px;background:#000;color:#fff;font-size:clamp(14px,3.8vw,15px);font-weight:800;text-align:center;text-decoration:none;\" href=\"https:\/\/www.abrasteel.com\/wp-content\/uploads\/2022\/06\/Catalogo2017.pdf\" target=\"_blank\" rel=\"noopener\">Download catalogue<\/a><\/div>\n<\/article>\n","protected":false},"excerpt":{"rendered":"<p>Finishing and polishing Technical guide to choosing polishing discs for the maritime sector: restoring deck stainless attacked by salt, polishing handrails without removing them, fittings in the port workshop and keeping the shine between port calls.
