I stand by my recommendation Miden a little WD40 in the pot will clean it. I've used it for this for years with no problem. I believe the solvent in WD40 is fish oil based, regardless it works well. Air will just move the dust around. You don't spray it into the keyboard. You use the red tube and just spray a little directly into the pot. And yes you need to use resin core solder.
No problem Tom...different strokes etc..
I thought I would post this little excerpt though just to clarify:
WD-40's formula is a trade secret. The product is not patented, to avoid completely disclosing its ingredients.
WD-40's main ingredients, according to U.S. Material Safety Data Sheet information, are:
51% Stoddard solvent (essentially White Spirit)
25% liquefied petroleum gas (presumably as a propellant; carbon dioxide is now used instead to reduce WD-40's considerable flammability)
15+% mineral oil (light lubricating oil)
10-% inert ingredients
The German version of the mandatory EU safety sheet lists the following safety-relevant ingredients:
60–80% heavy naphtha (petroleum product), hydrogen treated
1–5% carbon dioxide
