Not that you would take a mop to your television, but there are definitely ways to, and ways not to, clean it properly. All the tips you should need are below.
Cleaning the screen
Cleaning the frame and body
If you'd like to clean your screen and keep it dust free for a while, try this little-known trick:
1. To be safe, unplug your television before cleaning.
2. Wet a soft cloth in a mixture of lukewarm water, and a little liquid fabric softener or dishwashing detergent.
3. Wring the cloth until it's almost dry, and then use it to wipe the screen.
For removing dust and dirt from the rest of your television, we recommend a soft, dry, lint-free cloth. With some models, LG provides a special cleaning cloth, right in the box. Never use a wet cloth on these portions of the television.
