MG Chemicals 401B-140G, Nu-Trol Control Cleaner, 5 oz., Aerosol, Case of 10
MG Chemicals 401B-140G — Nu-Trol Control Cleaner, 5oz Aerosol, Case of 10
MG Chemicals 401B-140G Nu-Trol (SKU: 401B-140G) is a unique blend of high-purity solvents and lubricating mineral oil formulated for cleaning and lubricating delicate moving parts in electronic controls. Nu-Trol dissolves flux residue, oxidation, oils, and contaminants from potentiometers, rotary switches, slide controls, relays, and electrical contacts — then leaves a thin lubricating film to restore smooth operation and reduce wear. Safe on most plastics. Supplied in 5oz (140g) aerosol cans, case of 10.

Key Features
- Cleans and lubricates in one step — high-purity solvents dissolve contaminants while mineral oil leaves a protective lubricating film; no separate lubricant application needed
- Restores noisy or scratchy controls — removes oxidation, flux residue, and debris from potentiometers, rotary switches, and slide controls to restore smooth, quiet operation
- Safe on most plastics — formulated to be compatible with the plastic housings and components common in electronic controls
- Precision aerosol delivery — aerosol format with extension tube for targeted application inside controls, switches, and connectors without disassembly
- Reduces wear — lubricating mineral oil film reduces friction and wear on moving contact surfaces, extending control life
Frequently Asked Questions
What is the difference between Nu-Trol and a standard contact cleaner?
Standard contact cleaners (like MG Chemicals 801B) are designed to clean and evaporate completely — leaving no residue. Nu-Trol is specifically formulated for controls and moving parts: it cleans like a contact cleaner but intentionally leaves a thin lubricating mineral oil film to reduce friction and wear on potentiometers, rotary switches, and slide controls. Use Nu-Trol when lubrication is needed; use a residue-free contact cleaner when lubrication is not desired (e.g., relay contacts, PCB connectors).
What types of controls is Nu-Trol designed for?
Nu-Trol is ideal for potentiometers (volume controls, trim pots), rotary switches, slide controls, faders, variable resistors, and other mechanical controls in audio equipment, test instruments, industrial controls, and consumer electronics. It is also suitable for relay contacts, electrical connectors, and switch contacts where light lubrication is acceptable.
Will Nu-Trol damage plastic housings?
Nu-Trol is formulated to be safe on most plastics commonly used in electronic controls. However, some aggressive plastics (such as certain polycarbonates or ABS formulations) may be sensitive to solvent-based cleaners. Test on an inconspicuous area before full application if you are unsure about plastic compatibility. Refer to the MG Chemicals TDS for specific plastic compatibility data.
How do I apply Nu-Trol to a potentiometer or rotary switch?
Attach the extension tube to the aerosol nozzle and insert it into the control’s opening or vent hole. Apply a short burst of Nu-Trol while rotating the control through its full range of motion. Repeat as needed. The solvent will dissolve contaminants and the mineral oil will distribute evenly across the contact surfaces. Allow a few minutes for the solvent to evaporate before returning the control to service.
