A friend recommended these to me and oh my goodness, they work so well. I was able to remove mold and mildew stains from my pontoon boat seats quite quickly with a reasonable amount of effort. Yes, it will require some elbow grease, but these remove stains that I could not get off with any other product. I included some before, after, and during photos, but they do not do it justice. My seats look several years, newer than they looked prior to cleaning. If you use these once a year, it would keep your seats looking like new. I only used one for my entire pontoon boat, and it still seems to be perfectly fine.

Excellent cleaning product for the boat

Love these eraser sponges. My boat is docked in the lagoon all summer. The bay feeds into all the many lagoons that make up our community. It can get quite mucky after storms and if the water is still on hot days. These amazing sponges tackled the worst green algae and more in minutes. The inside boat is sparkling after a summer of fun on the bay too! Highly recommend. I’m buying more.

Did a good job

Highly satisfied! Makes my boat look like new! Easy to remove mold and scuff marks.

I used these on a filthy HDPE kayak and they cleaned it up well: I was pleased. Afterwards, I learned that these "Magic Eraser"-type melamine foam products work via non-biodegradable microplastic abrasion. As the "sponges" rapidly wear down during use, the microplastic bits follow the rinse water into the environment where they can enter the natural food chain and exist for a long time. In summary, these scrubbers cleaned my boat just as they were intended to, but we shouldn't be using this technology and I will not buy any more of them.

The best cleaner I’ve tried for boat seats. It removed stains that I’ve been trying to remove for years.

I used these and some mildew spray to clean up these jet skis that were sitting under a tree. They were absolutely disgusting and between the spray and these everything basically wiped right off. It’s like a Mr magic eraser but for jet skis. Easy and fast to use, saved me a lot of time cleaning them up. Great for the price
