Fiberglass Boat Hull Cleaner, Marine-Grade Stain Remover & Restorer, Deck Cleaner for Boats, Pontoons, Sailboats, Pro Wash Cleaning Supplies

We had some red residue from a local lake. Had tried scrubbing with various cleaners with no luck. This and the deck cleaner were amazing. Leaf stains gone water stains gone. Now both are my go to. Also used the mold mildew remover on vinyl seat cushions and it works like a charm! So glad I found this company. Now my go to products.

Good stuff, takes everything off of a dirty hull.

The boys at the marina did a poor job of cleaning my boat, so I did what I should have done in the first place and cleaned it myself. I got a sprayer attachment from Home Depot that fits on top of the bottle and has a battery powered sprayer with adjustable wand. Started with a 3-foot-wide pattern from the bottom of the hull up to the chine, then waited a couple minutes. Picked up the hose to rinse it down and streams of brown were already dripping off! Had it not been for a constantly shifting breeze, I'd have finished my 18-foot bow runner in less than a half hour.That brings me to the warning part. This has oxalic acid in it, which will irritate and potentially cause great harm to soft tissue if inhaled, swallowed, gets in your eyes, etc. I caught a bit as the wind shifted and inhaled some fumes. Not much, but it took ten minutes of fresh water & fresh air to get myself right! I recommend wearing a mouth & nose mask AND a full face mask to protect breathing passageways and eyes.

What can I say? This product is incredible and very puzzling at the same time. I used a sprayer from a Windex bottle to apply. As soon as you spray this on the hull the dirt starts dripping down and disappears in a matter of seconds. Just bought our boat (pictured) and honestly would even have thought that there was anything under the caked on dirt/clay, but even that disappeared. I use the term "suspicious" based on what chemicals are in this and if it will have any effect to the surface of the hull in the long run. USE A MASK WHEN APPLYING! I've recommended allready to friends and family. Going to buy another one soon to have onel hand.

Great

It did do a good job in breaking up the hardest of Barnacle buildup, but it still took a ton of pressure washing to clean my boat. I’m glad I used it once but I probably will not ever use it again. Definitely doesn’t spray on and wash off, it is not a miracle.

Used the entire bottle per the instructions and it made no difference at all ! I’d do zero stars if I could , late delivery too so I wouldn’t expect it on time if needed .

This stuff worked like magic! I bought a new spray bottle from the dollar store, poured this cleaner in, sprayed the boat down with the solvent, waited 2 to 3 minutes to allow the solvent to break down the debris (got a cold beverage, sat in a chair, listened to music), and then I sprayed down the hull of the boat with a low pressure hose. What a difference this made! The water line (we have a lot of tannin in NE Florida) just disappeared. After I was done with the hull cleaner, I used a “ceramic” waterless wash, shine, and protectant. The little bit of residue that was left on the hull of the boat just wiped write off with a light swipe of the microfiber cloth after I sprayed the hull with the ceramic armor cleaner. I bought this boat used and hired a professional to clean & wax the boat last year and it didn’t compare to the shine I got with this hull cleaner and the ceramic wash / protectant I used. It was simple and easy to use and didn’t break my back to do it. Highly recommend this stuff, it’s a MUST for boat owners. By the way, I have a 22’ center console with 8’6” beam and used a full bottle plus a partial bottle (maybe 20% of the 2nd bottle).
