If your banger is broke, you need a new one.
If your banger is looking white (called chazzed), this is from overheating the banger with oils in it. The carbon from the burnt oils actually start to become part of the quartz glass, making it weak.
If your banger is black, you can clean it in a super soaker and some alcohol.
Even a chazzed banger will still work. If you like is clear, do not overheat and learn more about cold start dab.
