Electrical Parts Cleaners for Contacts

Less harsh than general purpose electrical cleaners, these cleaners are suitable for the delicate contacts in electronics and printed circuit boards. They remove oxidation and corrosion from metal surfaces, giving your components long-lasting protection and reducing connection failures.

Pens

Pens have a round tip that can be used to precisely clean delicate contacts. They also contain an additive that improves conductivity. These pens are small enough to fit in your toolbox or carry in your pocket.

Aerosol Cans

NSF Registered K2 and NSF Registered P1—Cleaners that are NSF registered K2 or NSF registered P1 can be used in food-processing environments.

Flip-Up Straw—Aerosol cans with a flip-up straw have a straw that’s attached to the nozzle so it won’t get lost. Raise it for precision dispensing; lower it for storage or to dispense cleaner as a spray.

Cannot Be Sold To—Product labeling requirements and/or PFAS regulations restrict sales to the listed jurisdictions/areas.

Electrical Parts Cleaners for Fiber Optic Connectors

Clean plugs or adapters on fiber-optic cords. These handheld cleaners remove dust, dirt, and grime with a lint-free fabric so cords can send data without disruptions caused by debris.

For Plugs—Plastic Case

Cleaners with a plastic case have a cleaning window for wiping debris off of plugs. Slide the cleaner to feed a fresh piece of cleaning fabric across the window.

For Plugs and Bulkhead Adapters—Plastic Handle

Cleaners with a plastic handle have a cleaning tip for plugs and adapters. Flip open the cap to clean a plug, or remove the cap to clean a recessed adapter. Click the tool to push the cleaning fabric through the tip—each click pushes through a fresh cleaning surface. They also have an extendable nozzle, which lengthens them by an extra 1.5 in. to clean deep ports or crowded panels.
