How Sony recommends cleaning TV remotes: damp cloth, then dry cloth
Sony recommends a cloth moistened with diluted neutral detergent, wrung thoroughly, followed by a light wipe with a dry cloth. Keep liquid out of button gaps.
Spraying cleaner directly onto a remote can let liquid seep between its buttons. Sony's TV-care guidance calls for using a properly wrung cloth instead. Voice, rechargeable or specially sealed remotes may have different materials and instructions; check the model manual first.
