CAIG LABORATORIES DeoxIT D100L Brush Contact Cleaner 7.4 mL — Restores Conductivity & Protects Contacts

DeoxIT D100L-2DB is a brush-top contact treatment that cleans, protects, and restores electrical connections to improve conductivity and reduce intermittent faults.

Designed by CAIG LABORATORIES for pro and hobby electronics maintenance, this 7.4 mL brush applicator targets oxidation, corrosion, and grime on metal contacts without leaving conductive residue. It combines cleaning action with a protective film and light lubrication so plugs, sockets, switches, and connectors operate more reliably and make better electrical contact.

How quickly does DeoxIT restore signal and conductivity?

Most users see immediate improvement after one treatment: oxidized surfaces are dissolved and contact resistance typically drops, improving audio, data, and power transfer. Results depend on corrosion severity and contact type.

• Works instantly on light oxidation and grime
• Reduces intermittent noise and signal dropouts
• Improves conductivity for analog and digital connectors

What surfaces and connectors can I safely treat?

DeoxIT is formulated for metal-to-metal electrical interfaces, including plated and bare metals commonly found in electronics. Avoid painted or insulated surfaces where solvent action could damage the finish.

• Suitable for RCA, XLR, USB, HDMI, Ethernet and audio jacks
• Safe on switches, relays, light bulb contacts, and battery terminals
• Not intended for plastic finishes or coated insulators

How do I apply the brush applicator for best results?

The attached brush lets you accurately place product on contact surfaces and into small crevices. Use short strokes to scrub the contact, allow dwell time to loosen deposits, then cycle the connector several times to wipe away debris.

• Brush onto contact area, scrub gently, then wipe excess
• Cycle connectors while drying to polish mating surfaces
• Use sparingly — small volume covers many contacts

Will DeoxIT cause shorts or leave conductive residue?

Formulated to improve conductivity without creating shorts, DeoxIT evaporates and leaves a protective, non-conductive film that reduces wear and resists moisture. Avoid over-application in tightly packed assemblies where excess could migrate.

• Evaporates cleanly; designed not to bridge contacts
• Provides light lubrication and corrosion protection
• Displaces moisture and prevents future oxidation

Who is this for: This CAIG LABORATORIES DeoxIT brush applicator suits technicians, audio/video installers, electronics hobbyists, and anyone maintaining vehicles, instrumentation, or household electronics. It’s ideal when you need precise application in confined spaces, want to restore intermittent connections, or seek a long-lasting protective treatment for plugs, jacks, switches, and other metal electrical contacts.

• Features: Removes oxidation and corrosion to restore electrical integrity
• Improves conductivity and signal quality without causing shorts
• Lubricates, seals, and protects contacts from wear and vibration
• Displaces moisture and contaminants for long-lasting reliability
• Compatible with batteries, light bulb contacts, switches, relays, jacks, plugs, wiring harnesses, grounding blocks, RCA, XLR, USB, HDMI, Ethernet, and other connectors
