Sky remotes are manufactured to work with Sky Digibox digital cable television systems. After using your Sky remote for an extended period of time, grime and dirt can build up on and around the buttons, causing them to stick when you press them. Clean this build-up to get your remote working properly again.
Pour some alcohol in a small bowl or container.
Dip a cotton swab in the alcohol. Make sure the cotton swab is not too wet. If it is too wet, press it against the bowl or container to release the excess alcohol, or squeeze some of the alcohol with your finger.
Clean the buttons using the cotton swab. Rub the cotton swab gently to avoid rubbing off the numbers or letters. Clean on and around the edge of each button to get at the grime that makes your remote sticky when your press the buttons. Use as many cotton swabs as necessary. Ideally, use a new cotton swab once the one you are using gets too dirty.
Rub a dry cotton swab on the areas you have cleaned to dry any excess alcohol and to remove the rest of the grime.
Clean your Sky remote's buttons regularly to avoid build-up; if there is no build-up you can use water instead of alcohol. The longer you wait to clean your remote's buttons, the more tedious the cleaning task will be.
