I thought I'd share this... I had a Dillon powder measure for over 20 years. the plastic hopper got so dark from the powder that I couldn't see the powder level. Tried using alcohol, dish soap, bleach solution and a few others cleaning products to no avail.
had a bottle of Goo Gone for removing dried grease and sticky film from tape. Tried it and was amazed. It works extremely well on carbon build-up on revolver cylinder flutes and faces too. just a wet patch with finger pressure will do the trick. Smells nice afterwards.
However, it is flammable as indicated on the label so use it in a well vented area and away from heat/spark sources.
