BW-100 Electronic Contact Cleaner Spray 4oz (114g) Pack of 3 — Non‑Flammable, Fast‑Evaporating

BW-100 is a fast-evaporating, non-flammable electronic contact cleaner spray designed to remove dust, grime and contaminants from connectors, switches and circuit boards without leaving residue.

Designed for delicate electronics, BW-100 cleans contact points and moving parts safely and quickly. The formula evaporates rapidly to minimize downtime and reduce the risk of shorting, while being compatible with many metals, rubbers and plastics. Each 4 oz (114 g) aerosol includes a precision extension straw to reach tight spots, and this listing includes a convenient three-pack for routine maintenance or workshop use.

How does BW-100 improve electrical connections?

By dissolving and clearing dust, oils and oxidation from contact surfaces, BW-100 helps restore reliable conductive paths. It leaves no sticky residue, so moving parts like switches and relays can return to smooth operation.

• Removes common contaminants that impede conductivity
• Rapid evaporation reduces risk of moisture-related faults
• Precision spray targets connectors and contact points
• Safe for routine preventive maintenance

Where can I safely use this contact cleaner?

Use BW-100 on metal connectors, printed circuit boards, relay and switch contacts, potentiometers, and joystick assemblies. Avoid spraying onto screens, keyboards, or adhesive bonds; always test on a small hidden area if compatibility is uncertain.

• Ideal for PCBs, connectors, switches, and mechanical contacts
• Compatible with many plastics and rubbers—spot test recommended
• Not intended for LCD/OLED displays, sealed keybeds, or glued joints
• Extension straw reaches recessed or clustered components

How should I apply BW-100 for best results?

Work in a well-ventilated area and power down equipment before spraying. Use short bursts, allow the cleaner to evaporate fully, and actuate switches several times to dislodge loosened deposits.

• Turn off and unplug equipment before cleaning
• Hold can upright and use extension straw for precision
• Spray brief pulses; allow complete evaporation between passes
• Operate contacts after cleaning to help remove residual debris

What precautions should I take when using this spray?

Although non-flammable, BW-100 is a chemical aerosol—avoid inhalation and prolonged skin contact. Keep away from open flames and excessive heat, and store cans upright in a cool, dry place out of reach of children and pets.

• Work in ventilated spaces and avoid breathing fumes
• Wear gloves if prolonged contact is expected
• Do not spray on screens, adhesives, or energized circuits
• Dispose of empty cans according to local regulations

Who is this for: BW-100 is aimed at electronics technicians, hobbyists, AV installers, gamers maintaining controllers and joysticks, and anyone who services small electronic equipment. If you need a quick-drying, non-flammable cleaner to maintain reliable electrical contacts without residue, this three-pack of 4 oz aerosol cans offers a practical, workshop-ready solution.
