what are the called, and can I pick them up at wal-mart? I need to clean my interior and it has some stuff in it normal l washing is not removing. Thanks.

Mr. Clean magic eraser. Sold in the cleaning products aisle. Wally World should have them.

Most supermarkets have them too. Just don't use them on shiny surfaces other than glass. They have some type of abrasive in them. But they work fantastic on vinyl.

And don't rub too hard on your vinyl!! They work great!

those things are the shiz-nit, I used a couple yesterday
