MEK, Methyl Ethyl Ketone. 10 bucks for a can at Home Depot. Go to Bed Bath and Beyond and pick up a Tea Strainer for 3 bucks. You put some of the MEK in a Mason Jar and you can keep reusing it. The Tea Strainer is a round wire mesh clamp thingy that holds all the diff parts perfectly. The MEK cuts the silicone and crud better than anything. Let the parts soak for a few minutes, swish them around and lay them out to dry. It's that easy. DO NOT put anything plastic or rubber in the MEK.
