Newbie here and I hate to make my first post going against the grain, but I disagree.
Acetone does not expand the cellulose into a gunk like consistency like methanol does, it leaves it in a powder form. And it does not leave behind any residue either. Acetone is very nice to work with IMO.
Residue on Evaporation,
g/ 100 ml. (max.)= .004
acetone is less toxic then methanol.
About 2 to 3 milliliters per kilogram for children may be considered a toxic oral dose.
if you like methanol better that's fine, but nothing wrong with using acetone.
