🧪 Fiberglass Acid Hull Cleaner - Bio-Kleen M01609, 1 Gallon Review

Tried the boat cleaner first. The sea foam could not be washed off. But then I applied this product, just wiped it off with a regular hand wiper and then washed the boat. The boat looks new. Easy to use. Just make sure you use the correct personal protective equipment when using this product.

Works very quickly on the eyes without chafing. Applies easily with a cloth or sponge roller and rinses off after 30-60 seconds. Did not damage our boat's vinyl or fiberglass in any way. Good things.

This product requires more scrubbing than advertised (read: lots of scrubbing with a stiff brush and multiple uses) but it really works. We just bought a boat that had dried out from limescale for several years and we were able to get rid of it. A 23ft driver took about 2/3 of a jug and 6-8 hours to clean.

Tried it out on our pontoon after a friend used it on his V bottom hull. It was easy to spray on and the dirt from 9 months came off immediately. I hit it with a pressure washer and was done. The easiest fall cleanup in 20 seasons. Will use again. A gallon made a 22 foot pontoon, but I used all of them. I will buy 2 next season.

My 21 foot boat has been sailing the Sacramento River for months. Heavy fouling and algae stains. For the most part it worked. I had to apply several times to remove all stains. Most of the growth had to be pressure washed and scraped off. Use a garden sprayer to apply Bio-Clean. I have used other products that work better but have a stronger smell.

This is the only product we have found that actually removes water stains from our wakeboard. Spray on this substance, leave for a minute, rub (barely) with a soft brush, then rinse and dry. It's really adorable. Be careful though, this is a strong, smelly substance and will sting if it touches your skin. Don't use it on a windy day or near any grass/plants you like.
