When they get clogged up, I have been putting them in vodka for about 10 minutes max. Then blowing them out with comp air. In general it is not a good idea to let anything electrical sit while wet. Rubbing alcohol is denatured with pyridine, which has an awful taste and high bp. Absolute ethanol (100%) would be ideal, but it is very hard for a nonchemist to get. Used to be you could buy in a liquor store everclear, which was 95% alc. I don't drink so I haven't been to one lately, and haven't looked for everclear since my younger days!Someone else mentioned warm water. Thing is, most everything that gums up an atty is water soluble, and also ethanol soluble. Just blowing it out is sometimes not enough, especially when you are new and inexperienced and do all the wrong things.
As I think about it, acetone might be a good solvent. No water, dissolves the gunk, and dries fast and completely with some air. Not sure if there are any plastic parts that might dissolve however.
Not really making a point here, just discussing details...its just chem chat to me!

I have used canned air but no longer do. The force is such that it could dislodge wicking, metal mesh on the bridge, even break a wire. Plus it has a bittering agent that could coat the metal:

I use Galen's 151 vodka pure grain, charcoal fiter - @$12. To clean the shipping fluid, which is straight PG, from the atty I'll soak for 10 minutes and blow it out by mouth. For cleaning I'll soak for an hour or two and blow it out three ways - batt end, cart end and cart end closing off center hole to clear the intake holes. Dry on paper towel. Since I rotate attys, I'll put three drops of unflavored, no nic PG and store in a ziplock, bleeding the air out. 4 months and haven't lost one although I have one weak atty where I pulled out a strand of the bridge wicking.
