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!!

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 😂

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.

AMAZING STUFF!!! I couldn't believe how FAST and how WELL this stuff works! EASY to use -- spray and ignore! The only caveat is that it has a strong "bleach smell", so I just turn on the exhaust fan in the bathroom when I use it -- the smell is CLEAN, and that is EXACTLY what it does! When we cleaned out my brother's house after his passing, I "inherited" his garden angels; they were black with mold, but after spraying them with this, and "walking away", they were back to being white! I also sprayed the various bottles in the shower, and the mold, that nothing else could challenge, was GONE! I HEARTILY RECOMMEND THIS MAGIC SPRAY!

It did a fantastic job on my outdoor loveseat glider cushions. I wish I had taken a before picture. The only reason I am taking off a star is that I did not realize it was not supposed to be used on fabric until I started using it, and it had a strong bleach smell. However, when i looked at the label, it does not list ingredients. Since my cushions were tan, I could not see any discolorations except on the back of the cushion, where the back cushions rest on the bottom, which was no big deal. It looks fantastic and is cheaper than replacing the cushions. I do wish Amazon had not shipped this with my Subscribe & Save food items, because it had started to leak, but did not get on anything.
