Even a steam cleaner wont clean it....

An art eraser will take it off. The white, rubbery type....

For mud stains on interior surfaces, try our NEW Leather & Interior Cleaner with an Edgeless Utility Towel.

If you need more cleaning power, then use the NEW Interior Scrubbing Mitt with the cleaner.

If that still does not remove the stains, then step up to the Deep Clean Eraser with the cleaner.

Since many different cleaners can be strong, and the erasers are somewhat abrasive, it is best to use the least aggressive method first, and then move up to more aggressive methods as needed to remove more stubborn stains.
