Boat Non-Skid Deck Cleaner, Marine-Grade, for Fiberglass, Aluminum, Plastic, Vinyl, Composite Floors & Hulls, Wash Soap & Sealant Cleaning Supplies

I purchased this based on all the positive reviews. I tried this on a recently powerwashed boat which was covered all winter but still was pretty dirty. The powerwasher didn't get it very clean and left a lot to be desired so I looked for a cleaning solution and purchased the Large Boat Deck Cleaner. I was very disappointed. It didn't even make even the slightest dent in the cleaning up the deck. I used full-strength, brushed using a stiff brush, let it sit for the recommended several minutes -- nothing. Fortunately I had some outdoor bleach which I sprayed on and within minutes the deck was sparkling white again. Knowing that bleach is not really recommended, it did the trick. I would not waste my money on the Large Boat Deck Cleaner as it just doesn't work as advertised.

Cleaned our boat deck within minutes. Even the grime I couldn’t scrub off before came off. Def buying this again

This stuff is outstanding and I’ve tried a lot of cleaners. I put a sprayer in the bottle and apply it directly to the top side of my boats non skid surfaces. I scrub the deck with a stiff bristle brush and let it sit for a few minutes. Always come out Snow White! I’ll definitely buy again

Bought a couple products from better boat to try out this season. We put our boat into storage dirty last season so we really needed something strong to get the scum and grime off. Happy to say this product did the trick.Sprayed the deck down with water, applied this deck cleaner, let soak for a few minutes, then scrubbed lightly with a deck brush. Took all the gunk straight off. Just spray off with water when finished. My husband took some photos on his phone so I'll updload pics later but our deck is bright white now!Doesn't take much of the solution honestly. Bottle should last more than one season.

Works super good! Definitely going to buy again! We bought a used boat and been using it to clean it! Takes fish blood out pretty good too! And a little bit goes a looooong way

Very impressed. No elbow grease needed. Spray on and let it sit for few minutes and scrub. Rinsed off and never seen my boat so white.

This was very easy to use and made short work of my dirty boat deck. I did have some yellow stains that it didn't remove but otherwise the deck looks like new.

I have tried for years to somehow clean the textured surfaces on my Tiara to no avail. Nothing worked nearly as well as this stuff. My decks and floor look like new.
