It is not usually recommended to use glass or window cleaner on your TV screen, although some professional cleaning products may be safe to use. Make sure to check the label of the cleaning agent before using it on your TV.
Most modern TVs, such as LCD, plasma and rear-projection screens can’t handle wet cleaning. Parts may become damaged, and cleaning products can also damage the anti-glare coating on some screens.
You can remove dust and light marks from your TV using a simple dry cleaning method. You’ll need a microfibre cloth and a slightly moistened wipe that is specially designed for use with electronics. Give the screen a light dust and spot clean any stubborn marks or smudges using the moistened wipe.
If you are using glass cleaner, make sure you avoid spraying it directly onto the screen, as this can damage your TV.
