No Yellow Cleaner

Koch-Chemie No Yellow Cleaner — a pH-neutral cleaner that removes the yellow staining and yellowish algae that build up along the waterline and bow. It works on contact with no long dwell time, and also lifts rust stains and exhaust soot from the transom. The neutral formula is safe on plastic, stainless steel and aluminium, so you can use it with confidence around fittings.
