To prepare a board for toner transfer I've had good results by first 
giving the board a really good scrubbing with green Scotchbrite and 
dishwashing detergent. I follow this with a hot water rinse. Then I 
spray it down with Orange Blast and let it sit for a few minutes. 
Next is a good rinse in hot water. Finally I wash the board with 93%+ 
Isopropyl Alcohol from the drugstore then dry the board with a fan.

I like the alcohol instead of acetone; I think it's easier on the body.
