Works great

It worked amazing on our boat seats. There was a fair amount of mold from winter storage I was very impressed how they turned out.

Expensive but well worth the cost

When I first started looking for this product I thought the price was a little high but I figured from the reviews I’ve seen online and YouTube I would give it a shot. I’ve been trying to get some mold stains off my Sea-Doo seat for two years with no avail. Ordered the product online and once it came in, I followed the instructions and wow it was gone. Took no effort at all and no scrubbing. Just spray on and wiped it off. The seat looks like new. I’ve also used it on my RV and the same results. Worth every cent of the cost of this product. Have already recommended it to my fellow boaters.

Good Product

worked well and cleaned up the 35 year old vinyl seats to almost like new condition. Product might be a little over priced...I would suggest somewhere in the $20 range would be better. I have seen at some US marine stores at around $18 US,
