I need help soucing a certain product used to clean grease marks and scuffs from matboard. One of my customers said she used to be able to get this product in a spray bottle, which produced a white powder that you wiped off the matboard. Can anyone help?
If the scuffs are on one of the culprit matboards like certain dark greens and black, you can use those "dry cleaning" pads that Bill mentioned if the scuff is only on the surface. These board colors scuff by simply dragging another board across their surface (as in the warehouse guys pulling one out of a bin and dragging the corner over the adjacent board).
Greasy fingerprints are best minimized by washing your hands before touching a board. (That wasn't meant to be sarcastic.) Sometimes the dry cleaning pads will pull out most of the grease mark but not always. Sometimes naptha will work but not always. Sometimes Unseal will work but not always. Sometimes you have to bite the bullet, admit that you pulled out that board after downing a Big Mac and fries and use another board.
I remove scuffs from matboards by wetting a Q-tip with some distilled water and wringing it out so it is moist and swiping it the length of the scuff. I let it dry and, usually, it is gone. If not completely gone, I'll swipe again. Swiping is lightly done verses rubbing or scrubbing.
A scuff is a slight burnishing of the fibers and slightly wetting it raises the fibers. Most times it works just fine.
Grease (oily fingers), on the other hand SOMETIMES comes out with a little unseal. Usually not, tho. At that point, I figure I've already ruined it so I might as well experiment on it.
