/ Although stainless steel is widely used on board for its corrosion resistance, it is not completely immune to the harsh effects of the marine environment. Salt deposits, a lack of rinsing, or prolonged winter storage can lead to the appearance of rust spots and pitting on turnbuckles, stanchions, bulwarks, or cleats.
A non-abrasive chemical treatment for marine-grade stainless steel
Stainless steel maintenance often relies on abrasive products or polishing techniques that can eventually leave marks on the surfaces. NETTINOX gel, distributed by Matt Chem, works differently. Applied with a brush, it dissolves corrosion marks without any mechanical action. After letting it sit for 7 to 12 minutes, the product is rinsed off with fresh water.
This method may be useful on polished parts or stainless steel tubes where scratches caused by abrasive pads remain visible.
Passivation to Limit the Recurrence of Corrosion
In addition to cleaning, the product claims to have a passivation effect. This process involves restoring the protective layer of chromium oxide that naturally forms on the surface of stainless steel. This layer plays a key role in the material's resistance to corrosion.
The semi-gel formula also makes it easier to apply to complex parts such as candlestick bases, fittings, chain links, or certain vertical areas. The product adheres to surfaces without running excessively, allowing for targeted treatment without disassembly.
According to the manufacturer, a 250-ml bottle is sufficient to treat approximately 2 m² of stainless steel surface. NETTINOX is sold at a suggested retail price of ?20.50, including tax, for this size (price as of 2026).
