Just yesterday a girl was in my my Searay and when she stood up, the color didn't. That, I can forgive. But the fact that she was eating peanuts and putting the shells in the cuddy area of the bow rider.... I about lost it. This is a frickin' boat, not a baseball stadium !!!!!

The key is to use them with a vinyl cleaner or dawn dish soap water mix. It does not contain ANY abrasives, technically it is foam...see below.

Below is from BASF magic eraser PDF.

"Only surfaces liable
to scratching and varnished surfaces should not be
cleaned with the “magician”."

But it is abrasive and will remove the protective coatings on vinyl if you go nuts with them.

Ok!

It will go away with sunlight, I like to use star-brite vinyl conditioner and a hard bristle brush and wipe away with a micro-fiber towel.

Sunlight removed red bark mulch stain. Don't ask me how I know.

Crown works like a Charm!! Sit back in the Sun and sip the Spirits and watch all your troubles go down stream!

Might take 2 or 3 different attempts.

Have you tried them? I used them for at least 5 years with no I'll effects on my vinyl. Looked like new when I sold the boat mines gouges from a cooler. You make it sound like it's 40 grit. By definition a towel can be abrasive.

Over 10yrs here. Light swipes, make sure pad is full of water...no digging into threads.
Note: I only have to clean interior once a year.

Followed by 303 Protectant.

Note #2: I've learned to get the covers on the boat ASAP after we use the boat so the interior doesn't get burnt out.

Note #3: All white vinyl. No other colors.

thanks for all the suggestions I too have always used the magic erasers followed by some type of vinyl conditioner, I may have gone a little overboard on this one attempting to remove the stain but do damage has occurred I just cant stand a dirty boat. I have it down by 50% now I will try a few of the suggestions and then let the sun do the rest jut not sure I have enough trips to the lake yet this year to really get it faded away and it don't want it to sit all winter.
