ROWE HIGHTEC CONTACT SPRAY is a specialist cleaner that restores reliable performance to electrical contacts. It removes oxidation and dirt that cause resistance, improving conductivity and ensuring clean signal transmission. A protective film then shields the contacts against moisture and helps prevent recurring faults.

Purpose and specifications

This spray is designed for electrical connectors, plugs, switches, relays, fuse boxes and circuit boards in vehicles, electronics and household equipment. It removes oxidation and contamination from contacts, improves conductivity and protects against moisture to prevent contact faults. It is a universal service product with no OEM viscosity approvals, intended for the maintenance of electrical connections.

• 0.400L aerosol can with a fine spray for precise contact cleaning
• Dissolves oxidation and dirt to restore low-resistance conductivity
• Ensures reliable signal transmission across plugs and connectors
• Leaves a protective film that guards contacts against moisture and faults

When to use / change?

Use it when you encounter intermittent electrical faults, corroded plugs, flickering lights or poor connections, and as preventive care during electrical servicing. There is no fixed change interval; simply reapply when cleaning or protecting contacts. It works reliably across a wide ambient temperature range from roughly -30 C to +50 C. Unopened, the can keeps for approximately 5 years when stored cool, dry and away from direct sunlight.

Frequently asked questions

Is it safe on plastic connectors?
Yes. It is formulated for use on common electrical connectors, but test on a hidden area first if you are unsure about a sensitive plastic.

Should the circuit be switched off?
Yes. Always disconnect power before cleaning contacts and allow the spray to dry before reconnecting.

Will it fix a flickering connection?
If the cause is oxidation or dirt on the contact, cleaning with this spray often restores a stable connection; damaged wiring still needs repair.

Always read the directions on the can and verify suitability for your application before use.
