Unplug the charger from power, then clean the connector’s outer housing with a dry or slightly damp cloth, blow out loose grit with dry compressed air, and let any moisture dry before use. Do not spray liquids into the pins, do not use metal tools, and do not use abrasive pads on the contacts. If pins look burnt, pitted or bent, stop using the connector and have it replaced.
Step by Step
- 1. Make it safe: switch off the charger’s breaker or unplug a portable unit from the wall.
- 2. Inspect: look for grit, insects, water, discoloured or bent pins.
- 3. Remove loose debris: short bursts of dry compressed air or a soft dry brush.
- 4. Wipe the housing: microfibre cloth, slightly damp if needed; mild soap on the outside only.
- 5. Dry fully: leave it to air-dry before restoring power.
- 6. Test: start a session and watch for errors.
What to Avoid
| Avoid | Why |
|---|---|
| Spraying water or cleaner into the pins | Moisture causes ground-fault errors |
| Metal picks or screwdrivers | Damage contacts and plating |
| Abrasive pads or sandpaper | Remove contact plating |
| Lubricants not approved by the maker | Attract dirt; may affect contacts |
Prevention
Keep the connector in its holster or cap, hang the cable, and do not drop the connector on the ground. Chargers such as the EVDANCE EV-ACT5006T 48A Level 2 wall charger include a holster; portable units such as the EVDANCE EV-ACS3210E 32A Type 2 portable charger come with protective caps.
Frequently Asked Questions
Can I use contact cleaner on an EV connector?
Only if the charger manufacturer approves it; otherwise use dry methods.
How do I clean my car’s charging inlet?
The same way: dry cloth and air, never liquids into the pins.
Why does dirt cause charging errors?
Grit and moisture affect contact and can trigger ground-fault detection.
