Cleaning a TV remote in 6 steps: keep liquids off the buttons
The key is preventing moisture from entering the gaps around buttons. Check your model's instructions, then clean the outer surface gently.
TV remotes collect fingerprints and dust around their keys. Sony's BRAVIA 6 guidance recommends a soft damp cloth and warns against alcohol and household cleaners. That instruction applies to the specified model, so follow your own remote's manual first, particularly for rechargeable or solar remotes.
