Starke Ultra Clean SiO2 Soap

STARKE ULTRA CLEAN — SiO2 WASH SOAP

Every boat that carries a ceramic coating deserves a wash soap that works with the coating — not against it.

Ultra Clean is the Starke Clean System wash for ceramic-coated boats. The formula is pH-neutral and coating-safe — but what separates it from every other boat soap on the market is the SiO2 chemistry built directly into the formula. Every wash with Ultra Clean deposits a fresh layer of silica chemistry back into your ceramic coating. You're not just cleaning the boat. You're actively reinforcing the protection that's already there.

Most soaps — even pH-neutral ones — gradually deplete the surface silica over time. Every wash takes a little more off the top. Ultra Clean reverses that. Every wash puts a little back. Over a season of regular washing, the difference in coating performance between a boat maintained with Ultra Clean and one maintained with generic soap is measurable and visible.

Run it in a foam cannon or a bucket at the same dilution as Pure Clean. Same wash technique. Smarter chemistry. Pair it with Replenish monthly — Venom strip wash first, then Replenish — and you have the complete ceramic coating maintenance system that keeps your investment performing for 12 to 18 months.

Need more cutting power on a tough job? Add a measured amount of Simple Clean to the Ultra Clean wash to increase the cleaning strength without compromising the coating-safe chemistry for general wash sessions.

Available in 16 oz, 32 oz, and 128 oz.
