DeoxIT Gold GX100L-2DB｜Gx Extended-Temperature Protector (7.4 mL brush bottle)

The Gx series is Gold's extended-temperature formulation (about -45 to 310°C). It keeps the protection of gold and new contacts while coping with higher temperatures, wider temperature swings, or cabinet and outdoor environments. The brush bottle allows precise application.

Where to use it on high-end audio:

• Internal contacts on amplifiers and power amps that run hot for long hours.
• Sockets and plugs inside sealed, hot AV equipment racks.
• Mobile, outdoor or temporary live-sound rigs exposed to temperature swings.
• Cleaned gold contacts that need a longer-lasting, more environmentally tough film than standard Gold.

How to use:

1. Clean visible oxidation with the D-Series first and let the contact dry.
2. Brush a thin coat onto the contact and work it several times.
3. Wipe off excess; slight green or black discoloration is normal as oxidation dissolves—wipe and reapply.
4. On critical or hot-running gear, test a small area first before full treatment.
