You might try methyl alcohol (methanol). A great solvent when used properly.
Where gloves use as little as possible. I did this with a 4'x6' white board
and found no problems.
Now, where to get the methanol? VWR, Fischer, Columbus chemicals. Get the
least expensive, all grades increase price significantly because the
contaminants are detrimental for analytical chemistry uses.
Properly label and use the skull and crossbones. No drinking, it will lead
to attack of the retinal or optic nerves and destroy sight.
I know it's not friday yet, but for trivias sake, what is the emergency
response for methyl alcohol poisoning?
