Most vapers should replace coils rather than clean them. Stock pod and sub-ohm coils use a cotton wick that scorches with heat, so cleaning buys a day or two at most before flavor fades again.
Cleaning makes sense for rebuildable atomizers, where you replace the cotton and dry-burn the wire. For those, soak the coil in isopropyl alcohol, scrub the metal with a soft brush, rinse, and dry fully before re-wicking.
| Coil Type | Typical Lifespan | Cleanable? |
|---|---|---|
| Mesh sub-ohm (0.4-0.6 ohm) | 14-21 days | No, replace |
| MTL coil (1.0-1.8 ohm) | 3-4 weeks | No, replace |
| Pod coil (1.0-1.4 ohm) | 2-3 weeks | No, replace |
| Rebuildable (RDA/RTA) | Weeks with re-wicking | Yes, dry-burn and re-wick |
Replace the coil when you notice burnt taste, dark liquid in the tank, or weak vapor. Those three signs matter more than any calendar. If a device keeps misbehaving after a fresh coil, run through our vape troubleshooting guide before buying a replacement.
