You can use comet but then use denatured or 91pct isopropyl  alcohol to clean the soap residue off the board.
Then use a clean 3M pad to rough up the board.clean again with alcoholuntill no reside on the paper towel..

The last board I did, I only gave the copper a good scratch with some 
old sandpaper. Seemed to work quite well: I'm a long way from being 
certain, but I am working up to the belief that the toner needs a 
rough surface to get a grip on more than it needs a whole lot of 
solvents thrown at the copper. If I ever get certain, I'll sing out 
but I thought I'd share.
