Ran across this set ever the weekend, Plan to restore, Cleaned them up some over the weekend. My question, Got the great majority of old dirt and oil out of the drawers, but want to know what is the best product to finish cleaning up oil/grease that's left. Want something that won't leave a residue so can paint. The only rust is just thin surface patina, nothing major or deep,Can deal with that no prob. Got all the drawers freed already.
