Toluene

[Frank Evan Perdicaro]

Printers, real ones with big presses, need printing 
blankets to deal with the fact that ink has to be pressed
into paper.  These are not things that you put on your bed, but
another use of the term 'blanket'.

These things can get inked up, and are sometimes cleaned with 
generic toluene, "toluol".  Find the supplier for you local 
big-city newspaper.  They will probably have the stuff in 55 gallon
drums.

In eastern Massachusetts, the supplier is POSCO on the Wilmington/
Andover line, right next to route 93.
