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.

Amazing Product 🤩
This product is AMAZING! My pontoon seats look brand new. I ended up putting on gloves and after spraying the product I just rubbed the seat with my hands. The mildew just melted right off, and have had the stains for years. Highly recommend this product and will definitely purchase again.

Works great
This cleaned my outdoor cushions. It cleaned up mildew quickly! Used on our boat cushions also and it cleaned up mildew and spider poo. It is bleach based, so make sure you test a spot first. However I used on red cushions and it did not fade color.

Finally a product that works
I have never been moved to write a review and wish I would have taken “before” pics. We have been struggling with the rust on our older pontoon’s cream seats. Every year I would try a new product and it just kept spreading. Sprayed this product on, scrubbed a little w a brush and rinsed off. The rust is gone! Highly recommend.

Easy to use & effective
Using this spray to do Spring clean-up on my boat. It's super easy to use. Spray, agitate with a soft bristle brush & wipe clean with a wet cloth. No scrubbing or waiting needed! Mildew & dirt come right off & it leaves whites bright, colors vibrant.

Wow . I’ve tried many products that didn’t perform nearly as well
This product works EXACTLY how the company claims it does. I couldn’t have been happier by the way it cleaned my boat seats.The seat on the left looked exactly like the dirty mold stained seat on the right. I’d give this product 100 stars ps also got some back splatter on my pants so wear junk clothes when using.

Amazing product
We have a pontoon that had so many sun spots on the seats and felt like we tried everything. After trying many home remedies and other brands this was the one that worked the best! You won’t be disappointed
