Meguiar’s Extreme Marine Multi-Surface Cleaner M180332 - Pro Multi-Surface Cleaner for RV and Marine Detailing, Removes Dirt Grime & Stains from Vinyl, Gel Coat, Non Skid, Carpet and More, 32 Oz Spray

I bought a bottle of this for my boat clean-up....loved it. Now I have multiple bottles all over the house and garage because this stuff never disappoints on all surfaces.

My car had water stains and this product is very good for removing this type of stains I highly recommend it

Used on my outdoor cushions and took off ages of old mildew.

The Extreme Marine Multi-surface works on water spots, but beware, it will require alot of work. I bought both the Water Spot remover and the Extreme multi surface. The water spot remover is not as effective on tough, dried on water spots on a gel coat, (my wakesurf boat). The Extreme product is the only one thus far to remove most of the spots, about 80%, from my gel coat. It takes three to four treatments, followed by a lot of buffing.

Easy to use. I use it after I wash the boat to get rid of any stains I couldn’t get off with the brush. Just use a microfiber cloth and with a couple of wipes it gets the job done. Quick detailer and it does the job.
