Ah. The 2220B has a manual tuner in it. I assume it does something nasty to the rubber?

I just don't like breathing the stuff, and do worry about instantly removing all facial hair in a mini fireball.

The De-Oxit spray from Caig.com works wonders on older equipment. I resurrected an old Sanyo amp / reciever I had from the 80's...and an old Nikko for my neighbor across the street. You have to open the case and using the extension tube, find the pots small openings, spray some in and rotate a number of times from extreme to extreme. After it evaporates, fire it back up. You'll be suprised at the improvement...Been my experience...

Whoops, was going to respond to this earlier and forgot... I just wouldn't try cleaning a manual tuner with anything stronger than isopropyl alcohol... if they slip, the dial becomes useless, kind of finicky things.
Best results for cleaning is IPA (isopropyl alcohol) @ 100%; off the shelf "rubbing alcohol" is 70% IPA/30% de-ionized water usually... but sometimes can contain ethanol in some volume, not sure if it IS detrimental to electronics but I won't take the chance of using Russian vodka to clean my pots.

Methanol, ethanol and 2-propanol (aka isopropyl alcohol) are all fantastic cleaning chemicals with extraordinarily similar properties.
The longer carbon chain, yet still polar propanol makes it slightly better for removing grease type substances. It is also slightly less toxic than methanol if i remember correctly.
Ethanol should not bother your components although it is best consumed orally rather than poured onto cleaning rags for the wasting.
Save the Russian Vodka for the $20 speaker set with the shrilly high end. It might help tone down the high end a bit with a slightly laid back slur. The more you apply, the more laid back it gets!

Frightens me that the two guys from Manitoba are posting the most about ethanol and denatured alcohols.

As long as I can spray it, no problem. But I don't have the skill to take it apart very far. I'll try out the isopropyl, though. Thanks!

[nitpick]
It's impossible to have 100% isopropyl alcohol. As soon as it's exposed to air, it dilutes by absorbing moisture.
