Buy itโ๏ธ
I seldom review any products even if they are as advertise. However after using several products that claim to remove mildew stains from my pontoon boat seats and did not, I am glad I found Marine 31. It did the job. The seats look like new. Great product. Buy it, you will be pleased with the results.

Love this stuff! Works great on our boat. Just spray on, let it sit for a few then wipe away. Use this every year to get boat good and clean for boat season.

Use caution and rinse well
I was hesitant in the beginning due to the slight chlorine smell. I used it cautiously and did mostly spot cleaning and avoided seams as much as possible. I rinsed well. This is the best mold removal product Iโve found so far. I was surprised it removed or faded out so much of the worst mildew.
