DeoxIT Contact Care Kit G100L + D100L 1.6ml — Two-step cleaner and gold conditioner with precision brush applicators

DeoxIT Gold G100L and DeoxIT D100L are a two-step contact care kit: DeoxIT D gently removes contamination while DeoxIT Gold conditions and protects precious-metal and plated contacts for improved conductivity and lasting performance.

Keep connectors, switches and plated contacts working reliably with a compact pair of 1.6 ml brush-top vials. DeoxIT D100L is a fast-acting cleaner that dissolves oxidation and contaminants on metal surfaces; DeoxIT Gold G100L follows as a low-action conditioner that restores conductivity and lays down an anti-tarnish barrier on gold, silver, rhodium, copper and other precious metal surfaces. The brush applicators make precise, controlled application easy for delicate electronics, audio gear, and precision connectors.

How do these two liquids work together on damaged or dirty contacts?

Use DeoxIT D first when visible tarnish or corrosion is present; its stronger cleaning action breaks down oils, oxidation and grime. After the surface looks clean and dry, apply DeoxIT Gold to fine-tune conductivity and deposit a thin protective film that reduces future oxidation and intermittent connections.

• DeoxIT D: quicker-cleaning action for visible discoloration and heavy contamination.
• DeoxIT Gold: low-cleaning, high-conditioning formula for plated and precious metals.
• Brush applicators give precise coverage without overspray or wasted fluid.

Which connectors and metals are best treated with this kit?

The duo is formulated for a wide range of metal contacts: gold-plated pins, silver contacts, copper traces, nickel- and bronze-plated terminals, and delicate multi-pin connectors. DeoxIT Gold is especially suited as a final step on plated or precious-metal surfaces where only slight cleaning is needed and long-term protection is desired.

• Gold and silver-plated audio plugs, RCA, XLR, and instrument jacks.
• PCB edge connectors, card-edge fingers and low-current signal contacts.
• Precision switches, mechanical relays and sensor terminals.

Will these solutions help reduce noise, arcing or intermittent signals?

Yes—the combination targets the common causes of electrical noise and intermittent connections. DeoxIT D removes conductive contamination that causes poor contact; DeoxIT Gold then enhances metal-to-metal conductivity and leaves a thin anti-tarnish layer that reduces arcing and signal degradation over time.

• Reduces intermittent connections by removing oxidation and restoring metal contact.
• Helps decrease arcing and RFI by improving stable conductivity at mating surfaces.
• Forms a protective film that withstands temperature ranges typical in electronics.

How do I apply the products safely and effectively?

Work in a well-ventilated area and use the brush applicators to gently coat the contact surfaces—DeoxIT D first for any heavy contamination, then DeoxIT Gold as the finishing step. Allow each application to dry as recommended; small vials and brush tops make spot treatments simple without flooding sensitive circuitry.

• Apply DeoxIT D to visibly tarnished or dirty contacts; wipe away loosened residue.
• After cleaning and drying, brush on DeoxIT Gold for conditioning and protection.
• Avoid excess fluid on open circuits; test equipment after treatment.

Who is this for: technicians, audio engineers, instrument repairers, AV installers and hobbyists who maintain sensitive connectors and want a compact, two-step solution for cleaning and protecting metal contacts. This kit is ideal when you need a small, precise application—the brush-top 1.6 ml vials are portable and suitable for spot repairs, routine maintenance, and critical low-current signal connections where improved conductivity and long-term protection matter.
