Herschell Switch Cleaner is a high-performance, fast-evaporating solvent cleaner specifically formulated for the maintenance of delicate electrical and electronic components. It is designed to remove oil, grease, tarnish, and oxidation from contact surfaces to restore electrical continuity without leaving any oily residue behind.
Technical Specifications
- Base: High-purity hydrocarbon solvents
- Evaporation Rate: Rapid (seconds)
- Residue: Zero (Leaves a clinically clean surface)
- Dielectric Strength: High (Safe for most sensitive electronics)
- Volume: 400ml Aerosol
Key Features
- Oxidation Removal: Effectively chemically breaks down the "carbon tracking" and light oxidation that causes "scratchy" volume knobs or intermittent signal loss in switches.
- Plastic Safe: Generally safe for use on most modern plastics, rubbers, and resins found in electronic housings (though a spot test on vintage equipment is always recommended).
- Non-Conductive: Because it evaporates completely and has high dielectric properties, it reduces the risk of short-circuiting when the device is powered back on.
- Precision Application: Usually comes with a directional straw (extension tube) to reach deep into multi-pole switches, potentiometers, and tight circuit board clusters.
Common Applications
- Audio/Visual: Cleaning "crackling" potentiometers (volume sliders), guitar pickup switches, and amplifier inputs.
- Automotive: Cleaning MAF (Mass Air Flow) sensors, spark plug boots, fuse boxes, and ECU connectors.
- IT & Computing: Cleaning RAM slots, GPU connectors, and mechanical keyboard switches.
- Industrial: Degreasing relays, solenoids, and contactors in control panels.
Usage Tips
- Power Down: Always turn off and unplug the equipment before spraying. Never use on live circuits.
- Short Bursts: Use short, targeted bursts rather than a continuous spray to avoid over-cooling the component (which can cause moisture condensation).
- Mechanical Action: After spraying a switch or knob, toggle or turn it back and forth several times while the solvent is still wet to help mechanically "scrub" the contacts.
- Wait for Dryness: Allow 2–3 minutes for the solvent to fully evaporate before reconnecting the power to ensure no trapped vapors remain.
