/ Stainless steel maintenance is a must for every yachtsman. While stainless steel holds up well in salty air, it remains vulnerable to corrosion pitting, especially in the absence of appropriate treatment. In response to this problem, a triple-action gel is making a name for itself: NETTINOX.
Cleaning stainless steel without mechanical action: an asset for easy maintenance
Rust pitting on marine stainless steel sets in quickly, especially after wintering or unrinsed sailing. In such cases, the advantage of using a rust-removing gel is that it acts without rubbing. Simply apply with a brush, leave for 7 to 12 minutes, then rinse. This process is of interest to owners who want to avoid micro-scratches caused by abrasion, especially on polished tubes.
Passivation: the decisive step in preventing rust reappearance
A treated stainless steel does not mean a protected stainless steel over time. The role of passivating gel is fundamental here. Through chemical action, it reshapes the chromium oxide layer on the surface, a natural barrier against corrosion. This phenomenon, well known in industry, is rarely taken into account in routine maintenance. Yet it is decisive in preventing rust from returning, especially on boats that remain afloat.
Getting into nooks and crannies: a well-suited gel format
Stanchions, davit bases or chainplate screws present complex areas inaccessible to brushes or abrasive pads. Here, the semi-gel format ensures optimum adhesion to vertical surfaces. It conforms to the shape of parts without sinking, and remains in place for the duration of the action. This property facilitates targeted maintenance without dismantling, even when sailing or at anchor.
Application: a few simple rules to follow
Treatment requires a few basic precautions. We recommend avoiding application in direct sunlight, to avoid accelerating evaporation. The slightly acidic odour is indicative of an active chemical reaction: gloves and goggles are strongly recommended. After application, rinse thoroughly with fresh water to remove acid residues and protect surrounding surfaces.
Dosage and yield: a ready-to-use product
A 250 ml pot covers around two square meters. This coverage is ideal for occasional on-board maintenance, without excess material. Larger containers (1 liter) are aimed at professionals or vessels with numerous stainless steel fittings. In all cases, precise dosage and brush application help to limit waste and target the areas to be treated.
