Contact Cleaner Wago 249-130 20 ml

Wago 249-130 20 ml contact cleaner is a compact aerosol solution for cleaning electrical contacts and small mechanical parts. Designed to remove dirt, grease and light oxidation, this cleaner restores reliable conductivity and improves the performance of connectors, switches and relay contacts. Its small 20 ml format is suited to occasional maintenance tasks and repair work on electronic equipment where controlled, localized application is required.

Advantages

The formulation evaporates quickly leaving minimal residue, which reduces the risk of circuit contamination after treatment. The compact canister enables precise application in confined spaces and on delicate connectors. The cleaner is compatible with common metals and contact surfaces used in electronics, providing effective removal of contaminants without aggressive mechanical action.

Suitable for

• Cleaning connector pins and terminals in control cabinets and devices
• Maintenance of switches, relays and sensor contacts
• Repair and servicing of audio/video equipment and PCBs
• Preventive maintenance on automotive electrical connectors (non-sealed)

Key specifications

• Form: spray/aerosol in a 20 ml dispenser
• Primary function: removes dirt, grease and light oxidation from electrical contacts
• Evaporation: fast-drying, low-residue
• Compatibility: designed for common metals and electronic contact materials
• Application area: targeted, localized cleaning of small components

How to use

Before use, power off and, if possible, disconnect the equipment from any power source. Shake the can lightly and apply short bursts to the affected contact area from a suitable distance to avoid over-saturation. Allow the solvent to evaporate completely and inspect the contact; repeat treatment if necessary. After cleaning and drying, restore connections and perform a functional check to confirm improved conductivity.

Usage recommendations

Use in well-ventilated areas and avoid inhalation of vapors. Avoid contact with painted or plastic surfaces that may be sensitive to solvents; test on a small area if unsure. Keep away from heat and open flames and store at recommended temperatures. Follow local disposal regulations for empty aerosol containers.
