Contact Cleaners

During their lifespans, contacts, connectors and controls are exposed to a wide variety of contaminants, so they become corroded and wear out. This causes their connectivity to weaken and diminishes the performance of the electronics equipment they serve.

MG Chemicals’ contact cleaners are specifically formulated to clean, lubricate and protect these vital components, which restores and prolongs their conductivity and performance.

Is contact cleaner the same as WD40

They’re similar products so it’s possible WD40 might work in some applications like a contact cleaner since they help prevent oxidation. WD40 however, does leave oil behind so if cleaning connectors or contacts, you’d need to remove the residues whereas some contact cleaners contain fast drying solvents that do not need further cleaner after use.
Can I use contact cleaner on energized circuits

This is not recommended as cleaners are flammable so a spark may ignite the liquid. The cleaners are non-conductive however this does not mean they carry no charge so depending on the voltage and amperage, there is the potential to cause a short even with non-conductive materials.
