Well, SWIM ground up one box of Pair Ego 120 (exp 8/06) in his grinder, and rinsed it out with xylene. The grinder has a plastic lid, which contains a mechanism to trigger the grinding. SWIM then rinsed out his grinder with xylene.
When the xylene dried, SWIM was surprised to find a white crust on both sides of the plastic lid! It did not help to soak the lid in tap water for two hours. After that, it did not help to soak the inside of the lid with xylene for 1 hour.
Any idea what I can tell SWIM to use to clean the plastic lid? Is the white crust actually disintegrated plastic?
SWIM has never ground pills before, so he has no experience from which to draw. Thanks for any help, even if its just some search terms I didn't think of!
