Review: This product works great!! - A friend told me of this product to get rid of mold and mildew stains on vinyl. I have a car that has been in a garage for over 11 years. This product cleaned the seats even down to the creases. It is one of the best products I have purchased in a long time. It is great!!
Review: 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 😂

### ⭐⭐⭐⭐⭐ This stuff works like a dream
*by M***O on January 14, 2026*

My husband and I recently bought a five year old boat from an individual. The boat had been stored in a marina for most of its life, and its white upholstery looked like a Dalmatian’s coat due to mildew spotting. We had already budgeted in a reupholstery job, but figured we’d try to treat it just in case we could save the original cushions. We tried two different products (along with a whole lot of elbow grease) to no avail. I bought this stuff fully expecting more disappointment but was shocked by how well (and quickly) it worked. I sprayed it on a particularly bad spot on the upholstery and turned my back for a moment to pick up my nylon brush. By the time I turned around, the mildew was completely gone. I didn’t have to scrub at all. This stuff saved our upholstery and our wallets. If I ever find myself with a mildew problem on the boat again, I will save myself some time and money and start with this instead.
