Do you know of any commonly available solvents that will dissolve or soften the hardened residues on router bits? I know cleaners are available there [in the U.S.], but not here in Israel.
Kevin Hancock: Naphtha will clean off most residue on router bits. It is the main ingredient in lighter fluid.
John Brock: I’ve had good luck with Simple Green® for removing residue on router bits and saw blades. It may only be available in the U.S. and Canada.
Carol Reed: Here in the States, some household cleaning products are reported to be satisfactory, such as Simple Green. I use CMT Bit and Blade Cleaner which works extremely well. CMT is an Italian company. Surely you can get some via mail order.
Michael Dresdner: Lacquer thinner, acetone, and methyl ethyl ketone, all of which are commonly available solvents, will also work, as will most nonaqueous paint removers and refinishers.
