How to use

Before application, disconnect power to the equipment and, if possible, remove batteries or isolate the circuit. Shake the can well and apply short bursts of spray directly onto contact surfaces from a recommended distance of 10–20 cm, avoiding prolonged application on a single spot. Allow solvents to evaporate completely before re-energising the equipment. For persistent oxidation, repeat application and, if necessary, actuate the connector or switch to help dislodge deposits.

Usage recommendations

Use in a well-ventilated area and avoid inhalation of fumes. Keep away from open flames and hot surfaces; do not smoke during use. Test on an inconspicuous area if compatibility with plastics or coatings is a concern. Store the aerosol upright at room temperature and follow local regulations for disposal of empty cans.
