easy to use, let the stuff do the work, spray it on in the shade and let it sit.
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 😂

It’s Terrific!!!
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 works as advertised
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.

Works great, expires, cheap nozzle
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.

Excellent remover
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.

PWC seat
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.

Works as Described.
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.
