If it looks dirty or your flavor is off, it's time for a clean.
Additional Information: Over time, residues from concentrates can accumulate on your carb cap, affecting both its performance and the flavor of your dabs. Here are some signs that it's time for a cleaning:
Visual Build-up: If you notice a build-up of residue or a sticky, grimy appearance, that's a clear indication.
Altered Taste: If the flavor of your dabs starts to deviate from what you're used to, a dirty carb cap could be the culprit.
Smell: A strong, lingering odor on the carb cap is another telltale sign.
To clean it, you can soak the carb cap in isopropyl alcohol or a specialized cleaning solution for dabbing accessories. After soaking, use a soft brush to scrub away any remaining residues.
