Contact Cleaner Spray Technicqll 300 ml — Technicqll 5563-uniw, universal electronic contact cleaner

Technicqll Contact Cleaner Spray 300 ml is a universal electronic contact cleaner designed for maintenance and repair of electrical and electronic systems. Presented in an aerosol can for precise application, the spray removes dirt, grease, oxides and residues from switches, connectors, relay contacts and circuit components to restore reliable electrical contact and reduce contact resistance.

Advantages

The formulation evaporates rapidly without leaving conductive residues, enabling quick cleaning and immediate return to service. The aerosol format allows access to tight or recessed areas and provides controlled delivery for spot cleaning. Compatibility with common metal contacts and electronic materials makes it suitable for a wide range of applications in workshops, service centers and field repairs.

Suitable for

• Cleaning switches, relay contacts and mechanical contacts
• Maintaining connectors, pin headers and sockets
• Removing grease and oxidation from electronic circuit components
• Preparing contact surfaces prior to inspection or repair
• Routine maintenance of audio, video and communication equipment

Key specifications

• Volume: 300 ml aerosol can
• Application: electronic and electrical contact cleaning
• Evaporation: fast-drying, low residue
• Material compatibility: suitable for common metals and plastics used in electronics (consult manufacturer's guidance for sensitive materials)
• Delivery: spray/aerosol for targeted application

How to use

Before use, power down and unplug equipment. Shake the can well and apply short bursts to the contact area from a distance of 10–20 cm. Allow the solvent to evaporate completely before restoring power. For heavily soiled contacts, repeat application and wipe loosened contaminants with a lint-free cloth or brush. Avoid spraying onto powered circuitry, battery compartments or heat-sensitive components.

Usage recommendations

Use in a well-ventilated area and avoid inhalation of spray. Keep away from open flames and heat sources; ensure compatibility with plastics and coatings on delicate assemblies by testing on a small area first. Store the aerosol in an upright position at recommended temperatures and keep out of reach of children.
