Contrary to popular belief chrome requires regular care, for the chromium layer is very thin and prone to corrosion is not taken care of. Stainless steel is often used for rails, f…ings, swim ladders, windows frames and nods of Bimini tops etc. Although the material is stainless, it can nevertheless form rust deposits on the stainless steel surface. Especially when navigating saltwater, regular cleaning is therefore necessary to pre- vent rust stains on gelcoat or teak.
