I have had some crystallized gear in the past. Old cat named BL was trying to make high dose gear, but it kept crashing and therefore crystallizing. Do you know why yours is crystallizing?
What I did:
1. get a pot 2. fill with water low enough that you can put the bottle down in the water and it not cover the top of the bottle. 3. Boil the water 4. Remove the pot from heat source 5. let the boiling stop and get some of that hot hot heat off of it. 6. get a clean needle and put it in the top of your bottle so it can vent. 7. get some tongs and put the bottle in the hot water. (not your open pin, you don't want water in your gear) 8. Occasionally pull it out and swirl it around. 9. Rinse and repeat until the crystals are all gone. 10. Once it is cool enough to shoot remove the vent pin 11. Clean your bottle with alcohol, get a new pin, draw it, shoot it.
Good-luck!
