Hull Kleen - Acid Hull Cleaner

I used this on my 2016 Alumacraft 165 Classic in my driveway on a cloudy day. I sprayed about a third of a side at a time. Let it set 3 minutes, then brushed with a soft brush and washed it off. Used on aluminum hull, paint, decals, everywhere. No damage to anything, the hull is super clean. I used about a half bottle on my boat. Took my about an hour. Great product. I will never us anything else.

I've had severe build up of crud on hard to reach surfaces in my car wash. One of our team members brought in a small amount from home and tried it out. The crud is now history.

Works great. Quickly removes months of algae growth with minimal work

This works better than anything I have ever used. You spray it on and you can see it foam up and eat off any scale or build up it's an absolutely wonderful product. And it doesn't harm your finish.

Amazing!! My boat looks brand new! After more than 50 years of cleaning boats for winter storage in New England, Hull Clean made stain removal the easiest job I have ever seen! My neighbors were in awe over what an amazing job it did.
