The DeoxIT D100L-2C contact treatment is a fast-acting deoxidising solution that rejuvenates, lubricates, protects and improves conductivity on all metal based connectors that have metal-to-metal contact points.

It is perfect for use on the PlayStation Parallel Port to assist in the removal of existing oxidation or to act as a cleaner and rejuvenator to prevent potential future oxidation from occurring.

If you are having connection issues with your PSIO Cartridge, we highly recommend adding DeoxIT to the PlayStation Parallel Port.

The formulation is safe on plastics. We recommend wiping off any excess DeoxIT to leave a thin layer on the contacts. After application, if you notice a green or black discoloration (which may happen over time) this indicates DeoxIT is doing its job (IE: dissolving oxidation) and improving the connection.
