Remove the batteries from the remote control. This will eliminate the risk of damaging the batteries or accidentally changing the operation of the TV during the cleaning process.
Dip a cotton swab into a bottle of rubbing alcohol or some other type of cleaning solution. Do not fully immerse the cotton swab -- just get a little of the solution on the tip.
Rub the cleaning solution around the entire front of the remote. Get in between all the buttons on the front. Let the remote dry for up to to five minutes.
