## Key points

- Keep standard WD-40 away from electronics.
- Its residue can attract grime and pose electrical hazards.
- Use contact cleaner, isopropyl alcohol or compressed air instead.

## Summary

Standard WD-40 should not be used to clean sensitive electronics, because its petroleum-based formula leaves residue that can attract dust and dirt. The residue is also electrically conductive and flammable, creating a risk of short circuits or, in extreme cases, fire if it reaches internal components.

The article says WD-40 Specialist Contact Cleaner is designed to dry quickly, leave no residue and be nonconductive. For routine device cleaning, it suggests 90–99% isopropyl alcohol for dirty components, compressed air for fans and keyboards, and a good-quality microfibre cloth.
