Introduction: How to Clean Electrical Connections

Video tutorial on how to clean an electrical contact. Dirty or corroded contacts will cause conductivity issues, causing errors or interferences whether it be on computers, audio equipment, controllers, switches, connections, etc. This method can be applied to gold, silver, rhodium, copper, bronze, nickel, and other types of precious metals.

Tools/Supplies Needed:

  • contact cleaner
  • lint free cloth
  • can of air
  • brush

Step 1: Remove Loose Debris

Here I have an OBD1 Ford diagnostic tool and as you can see the contacts are dirty and in need of cleaning. First the part you are cleaning must be disconnected from the power source and possibly removed from it’s location depending on the application. Ensure the item is free of any loose debris, use the supplied cleaning brushes to remove the loose debris. A can of air can also help blow off the area.

Step 2: Apply D100L

Apply the D100L solution to the surface using the supplied brush. If you are working with a switching type device, it may required to operate for maximum cleaning action, wait a minute, then wipe off the surface, using a lint free cloth or swab. For excessive oxidization or corrosion, more solution may need to be applied and left over night, re-cleaned the next day. The cleaning tools can be used as an assist in cleaning as well. Wipe the surface off with a lint free cloth.

Step 3: Apply G100L

Now we are ready to apply the G100L solution. Same process, use the supplied brush and apply it to the contacts. The G100L solution is intended for maximum protection.

Step 4: All Done!

Wait 2 minutes before operation and now the equipment you have cleaned is now ready for usage.
