Coil Cleaning – What is it in Vaping?

Coil Cleaning

Definition

Coil cleaning is the process of removing built-up e-liquid residue, sweeteners and carbon deposits from the metal heating element (the coil) inside your vape atomiser or cartridge. By restoring the coil’s original surface area and electrical resistance, cleaning extends coil life, improves flavour clarity and prevents the burnt taste that signals a “dead” coil. Regular cleaning is a cost-saving, eco-friendly alternative to frequent coil replacement and is especially valuable for high-performance Clapton coils used in cloud-chasing setups.

Technical Details

Cleaning works by dissolving or mechanically lifting the gunk that insulates the coil wire, allowing heat to transfer efficiently to the surrounding cotton. Typical rebuildable coils (0.15–0.5 Ω Kanthal, Ni80 or stainless steel) can be cleaned 5–10 times before metal fatigue sets in. Two main methods are used:
Dry-burn & rinse: Pulse the device at 15–25 W until the coil glows evenly, then rinse under warm water or a quick alcohol dip to flush away ash.
Ultrasonic bath: Five minutes in 70 % isopropyl alcohol with gentle agitation removes stubborn residue without stressing the wire.
After cleaning, re-wick with fresh organic cotton and check resistance; a change of more than ±0.02 Ω indicates structural wear.

Usage & Tips

  • Frequency: Clean every 10–20 mL of sweet e-liquid or when flavour drops.
  • Beginners: Stick to simple spaced round-wire coils; intricate Clapton coils trap more gunk and need finer brushes.
  • Common problem: coil still tastes burnt—replace the cotton even if the coil looks clean.
  • Safety: Never dry-burn while the cotton is still inserted; ensure the coil is fully cool before re-wicking to avoid hot spots.

History & Context

Coil cleaning became common around 2014 as rebuildable dripping atomisers (RDAs) gained popularity among Australian cloud-chasing enthusiasts. Rising coil prices and environmental concerns have since made cleaning a mainstream maintenance habit across sub-ohm tanks and pod systems alike.
