- Mildew Stain Remover Gel Cleaner Kit | Removes Stains from Boats, Homes, Patios, Bathrooms, & Showers | Includes Interior Scrub Brush & Microfiber Towels | M31-375KITGEL-1 | 20oz

Product worked as advertised. Restored seats and upholstery to near new condition with minimal effort. I will be using every time clean up is required.

Online there are many advertised products that say they're the best. You buy it only to realize it's not. This product lives up to its's name, easy to use with proven results.

We have white seats and this stuff really did the job. We’ve tried others but this is by far the best we’ve ever used.

I have a 22 year old boat with white interior that was completely covered by mold. After a couple of hours cleaning. Looks almost new. I have tried several cleaners and this works fantastic. Use it for my shower at the house also !!! Great stuff. Like the gel better. Doesn’t run.

This product did make the mildew stain less noticeable but did not remove it. Know expectations when using it

We have used many different types of cleaners to clean the seats on our boat, and this product is amazing. Our pontoon boat is 20 years old and our seats were very dirty from the season. Using this product made them almost like new.

We had tried everything to take mold off our seats. This product worked and made our seats like new.

My husband and I have scrubbed the crap out of this cushion prior to trying Marine 31. We used Mr. Clean magic erasers, 401, bleach, etc. and nothing worked! These stubborn coastal living stains would not budge. I didn’t have to use much elbow grease at all with this product. I’m in shock. I was hesitant with the price but it’s so worth every penny!
