Marine 31 Mildew Stain Remover & Cleaner | Effective for Boats, Home, Patio, & Bathroom | Removes Mildew & Mold Stains | Powerful Cleaning Formula | 16oz

Literally made my 2006 all white boat interior look new! Almost no scrubbing needed. sprayed it till it was wet, let it sit for 5 minutes, and I have ZERO spots left of black. pure white again!! My seats were covered with black and I was about to have them re-covered (I have a few holes in the seats so I'm headed towards that anyway but this still might delay that by a few years. even my wife commented that the boat seats look new and asked it I had spent some money that we had not talked about 😂

This stuff totally works. We purchased a boat that had mildew and we tried several products that didn’t work. This did it. The boat looks brand new. We showed it to a neighbor at our lake and he tried it and it cleaned his boat seats and made them look brand new. He ended up ordering a gallon of it.

This product is amazing! It works as advertised. I have tried using multiple different products over the years to remove old mildew stains from my boat cushions and nothing worked. I tried this and they look like new. I highly recommend this product.

Amazing product, cleaned my boat seats and interior well. Be careful stuff is potent. Wear gloves. I used a blue tshirt as a cloth it turned it pink. Use a described on vinyl. Awesome product. Cleaned my seats, look like new now

Works great unless it gets too old. After two years, if you find it kinda not working, buy a new bottle.Gets the stubborn mildew off my white cushions with just a few sprays. The nozzle broke on my first bottle.

Why did you pick this product vs others?:It is the very best products. No scrubbing. Had some mildew spots for about a year we couldn’t get off. Sprayed, let it soak about 10 minutes and wiped off with a wet cloth.

Used on a Yamaha waverunner seat that was mostly black in mold. Tried all other products including power wash. I used as directed and did a couple times and seat was good as new. No scrubbing.

It does have a lot of bleach in it. Seems like you could make up your own mix of detergent and bleach if you deluted the bleach to a milder strength. Be sure to rinse it well, especially on the sewn threaded seams. Chlorine can be detrimental to certain fabrics over time.Also, use a quality vinyl protectant afterwards and let it get into the seams well to ensure longevity.
