Proper care extends the life of your power cord and ensures safe operation:
- Cleaning: Disconnect the cable from all power sources before cleaning. Wipe with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Storage: When not in use, coil the cable loosely. Avoid tight coiling or kinking, which can damage internal wires. Store in a cool, dry place away from direct sunlight.
- Regular Inspection: Periodically check the cable for any signs of wear, cuts, or damage, especially near the plugs. Replace immediately if damage is found.
