I have taken actions like you describe and boiled them in a solution of TSP (tri-sodium-phosphate, a degreaser available in the paint dept. of your local hardware store.)

I brush them out as best as possible and boil again in clean water, blow it out and drop the whole deal into water displacing oil and let it sit overnight. Blow off the excess oil and wipe down.

My problem lies in reconciling my gross habits with my net income.
