Contact cleaner spray K2 W125 400 ml – electrical contact cleaning aerosol

K2 KONTAKT SPRAY W125 is a 400 ml contact cleaner aerosol formulated for safe and effective cleaning of electrical and electronic contacts. The spray removes grease, oxides and other contaminants from switches, connectors, relays and printed circuit board contacts without leaving conductive or sticky residues. Designed for use in workshops, automotive maintenance and electronics servicing, the product helps restore reliable electrical conductivity and reduces the risk of corrosion and intermittent contacts.

Advantages

The aerosol delivers rapid evaporation and a residue-free finish, allowing cleaned components to be returned to service quickly. Its solvent blend dissolves oils and oxides while being safe for most metals and many plastics commonly found near electrical contacts. The targeted spray format enables precise application to confined connectors and contact points, minimizing overspray and waste.

Suitable for

• Cleaning switch contacts and connector pins
• Maintenance of relays and contactors
• Removing grease and oxides from PCB contact areas
• Automotive electrical system maintenance
• Workshop and industrial electrical troubleshooting

Key specifications

• Form: aerosol spray, 400 ml container
• Application: contact cleaning for electrical and electronic components
• Evaporation: fast-drying, low-residue solvent system
• Compatibility: suitable for most metal contacts and many plastics (test on sensitive plastics before use)
• Performance: removes grease, oxides and common contaminants to restore conductivity

How to use

Ensure the equipment is powered off and, where possible, disconnected from any power source. Shake the can briefly before use. Apply short bursts to the target contact area from a distance of 10–20 cm, allowing the solvent to dissolve contaminants. For persistent deposits, repeat application and use a soft brush or lint-free cloth to assist cleaning. Allow treated components to dry completely before reconnecting power or returning the device to service.

Usage recommendations

Use in a well-ventilated area and avoid inhalation of spray vapors. Keep away from open flame and hot surfaces; the product is flammable. Avoid prolonged contact with painted surfaces and sensitive plastics; test on an inconspicuous area if necessary. Follow local disposal regulations for empty aerosol containers and used cleaning residues.
