Hosa DeoxIT Contact Cleaner Spray — 5% 5 oz Aerosol, Removes Oxidation & Protects Contacts

Designed for technicians, audio engineers, and hobbyists, this 5% DeoxIT contact cleaner from CAIG (distributed by Hosa) removes oxidation and corrosion from metal surfaces to restore reliable electrical connectivity. Itʼs a multipurpose aerosol suitable for connectors, switches, potentiometers, and other small metal contacts where improved conductivity matters.

How does DeoxIT D5S-6 improve electrical connections?

DeoxIT chemically reduces oxides and corrosion that block electrical paths, then leaves a thin protective film that helps prevent re-oxidation. Unlike plain solvents that only clean, DeoxIT modifies the contact surface at a microscopic level to lower contact resistance.

• Breaks down oxide layers for improved conductivity
• Leaves a protective, non-gumming film
• Suitable for gold, silver, copper, and plated contacts

Where and when should I use this contact cleaner?

Use this spray on exposed connectors, audio jacks, PCB contacts, relays, and mechanical switch points when you observe intermittent signals, noise, or increased resistance. Itʼs ideal during routine maintenance, troubleshooting, or before long-term equipment storage to reduce future corrosion.

• Audio and video connectors, instrument jacks, and patch bays
• Electronic switches, potentiometers, and relay contacts
• Periodic preventive maintenance and repair situations

How do I apply DeoxIT safely and effectively?

Apply briefly and directly to the target contact; allow the solvent to evaporate and the protective film to set. Use in a well-ventilated area, avoid overspray on plastics when possible, and follow standard ESD precautions for sensitive electronics.

• Shake can, spray short bursts from 3–6 inches away
• Wipe excess with a lint-free cloth or brush for stubborn build-up
• Test on inconspicuous area if concerned about plastics or coatings
