How to Repair Remote Controls with WD-40

Use a screwdriver to carefully remove screws and open the remote.

Take note of button placement to ensure correct reassembly.

Step 2: Clean the Contacts

Dip a cotton swab lightly in WD-40 (do not soak it).

Gently rub the metal contacts on both the circuit board and buttons.

This helps remove oxidation, grime, and sticky residue that prevent proper contact.

Step 3: Dry and Wipe Excess

Use a dry cloth to wipe off any extra WD-40.

Let the remote sit for a few minutes to ensure no moisture remains.

Step 4: Reassemble and Test

Put the remote back together, replacing all buttons correctly.

Insert fresh batteries and test functionality.

Extra Tips

For sticky buttons, WD-40 can also help restore smooth pressing.

Avoid spraying directly into the remote—always use a swab or brush.

Repeat the process every few months for remotes that frequently lose connection.
