Here's an ugly problem...I am told. Wall grime. I am also told that it's hard to remove with products that won't hurt the paint and that the products that will remove it easily will also remove the paint. Those people bought GreaseMaster after I tested it on some wall grime. Click image to enlarge.

Even at 400:1, GreaseMaster easily removed the grime on this wall with nothing more than a paper towel. I followed up with a damp towel to remove any residue, although I couldn't feel anything once it dried in this application either. Click image to enlarge.
