The Hidden ROI of Residue-Free Dielectric Decontamination: Why 'Near-Clean' Is Still a Failure
Many maintenance teams use generic hardware-store contact cleaners or petroleum degreasers during switchboard servicing.

Within weeks, this tacky film traps airborne dust at 3× the normal rate, turning into a conductive sludge the moment humidity crosses 60% RH.
