Why a remote control fails
Remote controls work with simple circuitry that responds to button contact. With use, it is normal for residues to accumulate, for plaque to rust or for buttons to lose sensitivity. In addition, ambient humidity or liquid spillage can affect its internal functioning.
What you need:
WD-40 (preferably contact or multi-purpose)
A small screwdriver
Soft bristle swabs or brush
Dry cloth
Gloves (optional)
Step by step:
Disarm the remote: Remove the batteries and carefully open the case using a screwdriver.
Clean up the residue: Use a dry cotton swab to remove visible dust or dirt.
Apply WD-40: Spray a small amount onto a cotton swab or directly onto rusty areas. Don’t overwhelm the components.
Brush gently: Using a small brush, gently scrub the areas with dirt or corrosion.
Dry and reassemble: Wait a few minutes for the excess product to evaporate. Then, reassemble the controller.
Test its operation: Insert the batteries and verify that all the buttons respond correctly.
