Formulated with a special buffered acid that is easier to use than the traditional bottom cleaners. Ideal for cleaning baitwells, fish boxes or in-deck storage too.

DIRECTIONS

Allow marine deposits to dry. Pour product into an open plastic container and apply to surface of hull using a natural bristle brush. Keep the deposits and stains wet and foaming with the product.

EZ-ON, EZ-OFF is the most effective hull & bottom cleaner you can buy. The powerful formula works on even the toughest stains and deposits. If you have a dirty bottom, this is the solution. It's simply the best cleaner you can get - GUARANTEED.

EZ-ON, EZ-OFF uses high-tech buffered hydrochloric acids that aggressively attack the bond that "glues" deposits to the hull so you can scrape them off easier than ever. Most bottom cleaners contain old-fashioned hydrochloric and phosphoric acid formulas. Star brite's buffered formula makes EZ-ON, EZ-OFF easier to work with and gives better results.

This stuff is CRAZY!
After five years on the Mississippi I've learned the river scum is a real beast. After some research I decided to buy this Star Brite cleaner based on the reviews.GOOD - it was ridiculously good at removing the river scum. I haven't seen this white on the boat hull in years! When they say EZ-ON EZ-OFF it is just that powerful at removing the scum.BAD - this is a very dangerous chemical! The minute I opened the box and was hit by the chemical fumes it was apparent this is not your mom's cleaning solution. It literally burned my nasal passages as some had leaked in the packaging. Thankfully it didn't get anywhere else. Probably would have melted my vinyl entryway flooring.I also researched and bought a couple of brushes knowing that this was a very strong chemical. The first brush we used melted. After several dips and scrubs we realized it was leaving more black stuff on the hull than removing river scum. That was because it was melting from the chemical. The other brush didn't melt but it was not effective.We switched to rubber gloves (luckily I had some in the boat thanks to Covid Craziness) and hand towels which got things going and we were able to clean off the river scum. And the melted brush bristles.TIPS - be prepared. Be VERY prepared. This is a commercial grade cleaner that is a very strong chemical and must be handled with utmost care. Be somewhere you can rinse often - the boat, the ground, your skin. I would suspect this would kill everything in your yard if you were on the driveway. Lots of ventilation! Even though we were on a parking lot in the marina the fumes are super crazy. You don't want to be breathing this stuff. And finally, be prepared to rinse rinse rinse.BOTTOM LINE - this stuff works really really well but it is not for the faint of heart.

Reviewed in the United States on July 24, 2023
This boat is in the water April to October. I had to pull it out to replace the alternator. I pressure washed the thick stuff off. I bought this last fall and didn't get around to using it. After it dried yesterday, I put on some gloves, poured a bit on some paper towels and wiped for 30 seconds in this one area. It's amazing. I've tried all the acid toilet bowl cleaners scrub pads. I didn't think this was possible at this point.
