Contact cleaner spray Amtra CONTACT CLEANER 250 mL — electrical contact cleaner

Amtra CONTACT CLEANER 250 mL is a spray formulated for cleaning electrical and electronic contacts. It removes dirt, oxidation, grease and light corrosion from connectors, switches, relays and circuit board contacts to restore conductivity and reduce contact resistance when applied according to instructions. The aerosol format provides controlled application to small and hard-to-reach contact points without the need for full component disassembly.

Advantages

The cleaner evaporates quickly and leaves minimal residue, allowing rapid return to service for cleaned components. Its formulation targets contaminants such as oils and oxidation while being safe for use on most metals and common electronic materials. The compact 250 mL aerosol is convenient for maintenance and repair use, providing precise spray action and good nozzle control for targeted treatment.

Suitable for

• Cleaning connectors and plug contacts
• Removing oxidation from switches and relays
• Maintenance of printed circuit board contact points
• Preventive care of automotive and industrial electrical systems

Key specifications

• Form: aerosol spray, 250 mL
• Intended use: cleaning electrical and electronic contacts

How to use

Before use, disconnect power to the equipment and, where possible, remove batteries. Shake the can well. Apply short bursts of spray to the affected contact areas from a distance of approximately 10–20 cm, avoiding prolonged soaking. For heavily contaminated contacts, allow a brief dwell time then reapply and, if necessary, use a lint-free cloth or soft brush to remove loosened deposits. Allow the treated area to dry completely before restoring power.

Usage recommendations

Use in a well-ventilated area and avoid inhalation of spray mist. Do not apply to energized circuits. Test compatibility on an inconspicuous area if in doubt about plastics or coated surfaces. Store upright in a cool, dry place away from heat sources and open flame.
