Be sure to unplug the TV from the main wall outlet.

Carefully lay the TV screen down on a clean flat table with the back side facing you.

Using a #3 Phillips head screwdriver, remove the screws holding the back cover on.

Thoroughly clean the cover and boards using a damp towel (I like to use 91% isopropyl alcohol) and if heavily soiled use a vacuum with a brush.
