Who lets their knobs get dirty? Wash you hands first! Some of mine are from
the early days of NorCal and Elecraft. Maybe I don’t have much oil on my skin!
Ha! I have bought some used gear from the 1950’s and 60’s and sprayed them
with WD40. Rub til clean. Then dish soap and toothbrush if
UNinstall the knobs CAREFULLY. Wash in warm water with Dawn dishwashing
liquid and perhaps a toothbrush if soaking doesn't work.
Use compressed air to make double sure they are dry before
re-installation. Be CAREFUL with the set screws...

Dave,
+1 on Don's suggestion. I usually use some warm water and a mild dish
soap and let the knobs soak for awhile. Then I use a soft toothbrush to
remove any crud. I have done a whole bunch of K1 & K2 knobs like this
and it always works pretty well.

Dave,
I would suggest removing the knobs and clean them with dish washing
liquid, water and an old toothbrush.
Dry fully before putting them back on the K3.
