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 😂

Works as it should
Works good on black crud. I used this stuff to clean up some vinyl cushions on my salt water boat. I am talking years of nasty black mildewy stuff. Spray, sit for a couple minutes, spray again, brush, rinse. Maybe repeat, but cleaned up the mung. I would say be ready to apply some preservative once your project dries. Stuff works good. Smells a lot like bleach so I’m not sure this is not just a fancy presentation of that chemical.

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.

Cleans vinyl awesome
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

Great spray and rinse!
Worked very well on my patio stones that had spots of mold and mildew from an extremely damp spring. It wasn’t perfect but considering it is just a spray and rinse, it did exceptionally well! Very pleased!

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.
