[TenTec] On Contact Cleaning

[Dr. Gerald N. Johnson, P.E.]

Best I can detect, a little WD-40 only wastes the money it cost to buy
it. At the worst if it leaves a film to gather dust it can compromise
the insulation of a switch wafer and introduce abrasive dust to the
contact area.

One should be careful of carburetor (trichlor) in closed spaces. It can
give the user a euphoric high that is very rocky to come off of. Been
there. Felt like falling into a limestone quarry just after it had been
blasted.

73, Jerry, K0CQ
