I had made some case lube from 90% rubbing alcohol and some RCBS case lube in place of Lanolin. The problem was not the lubricity but the clean up. Tumbling with stainless pins resulted in dingy dull and dark shells. I had been out of lemishine so I used some lemon juice and dawn soap. I repeated this only the second time without the lemon juice. The shells came out looking no better. The crud wiped off with Rem Oil. This must have been the lube. I ended up rinsing and draining the entire lot in kerosene then running them in walnut media vibratory tumbler. Seems the dawn soap was unable to break down whatever was in the lube.
