Marine Acid Wash is an advanced triple action formula, with phosphorylated ethoxylate, for better hull cleaning results with lower acidity than other popular cleaners. It is ideal for removing slime, cleaning fibreglass hulls and for preparing surfaces for anti-fouling treatment.
Triple action:
  1. Excellent for renewal of fibreglass that is faded or stained from rust, exhaust fumes, environmental contamination etc.
  2. Ideal for removal of slime from hulls, anti-fouling and running gear.
  3. When used on anti-fouling, Marine Acid Wash etches the previous anti-fouling to provide a surface that binds to the new anti-fouling, ensuring better adhesion and longer life.
Our Stainless Steel Sentry is a perfect companion to Marine Acid Wash. It will provide long-term protection to all marine grade stainless steel.
Ideal for:
  • Boat hull cleaning
  • Faded or rust-stained fibreglass
  • Slime removal
