Description

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.

works very good on pontoon

"works very good on pontoon boats"

— Chris S. (5/5)

works good not great but

"works good not great but does what is advertised hard to get heavy marks out of non skid actually doesnt really get them out it gets black streaks off of ceramic coated surface but it takes a lot of scrubbing with a lambs wool pad"

— Ken H. (4/5)

Good product, bad packaging

"The soap itself is really awesome, but the bottle leaks easily and they should really consider new packaging. When it arrived in the mail about 1/3 of the bottle had spilled out all over the place."

— Laura P. (5/5)

Great Product from a Great

"Great Product from a Great Company!"

— Mike H. (5/5)

Possibly the best boat soap ever!

"For use on ceramic coated boats, but you can use it on anything and it will make it bead up like it's ceramic coated! 10/10 recommend"

— Adam D. (5/5)

Awesome product will by again

"Awesome product will by again"

— phillip e. (5/5)

Great choice for daily boat soap

"Ultra clean is a great for maintenance washes. It is just sudsy enough to spread out over the boat but not too much that it’s impossible to wash off and would leave streaks. I use it in a low pressure foam cannon and it works great. I switched from orpine to ultra clean because I felt I get a better clean and my hands don’t feel like they’re burning."

— Conner T. (5/5)
