DeoxIT D100L-2DB｜D-Series Contact Cleaner (7.4 mL brush bottle)

The D100L-2DB is the same D-Series formula in a larger 7.4 mL brush bottle, ideal for audio enthusiasts who treat several contacts at once. It targets visible oxidation and contact noise on older gear, restoring conductivity and fixing level fluctuations.

Where to use it on high-end audio:

• Annual care of a full system's RCA/XLR cables, loudspeaker plugs and power connectors.
• Tube pins and sockets on tube amplifiers and preamps to cure channel imbalance.
• Volume pots, source selectors and headphone outputs on analog components.
• Phono cartridge leads, RCA signal cables and ground lugs on turntables.

How to use:

1. Power off and unplug the connectors, tubes or open the control panel.
2. Brush the product directly onto the contact and work it several times.
3. Wait two minutes, wipe away residue, and repeat until the cloth stays clean.
4. Follow with Gold G-Series indoors, or Shield protection in demanding environments.
