Spilled fluids on screen

If the cushions are removable look on the back for a zipper. Carefully remove the fabric most manufacturin tell you not to wash them. Why do you put him on a gentle cycle and let him air dry it won't hurt them

take out each toner and look at the drum, are there line on them? if yes (most likely) than that is the problem the toners are leaking. If not clean inside with dry cloth, might just be some toner spill.

You gotta clean it with ethyl alcohol. (take the battery off first) and let it evaporate well.

One way to remove all types of stains and fingerprints is Windex and a soft rag. That is one of the cheapest and easiest way to do it.

A better approach to it is to use monster cleaner. It is a special spray to clean tv screens, laptop screens, and even windows. It comes with its own cloth that works amazingly well. I have used it for years and has worked for me every time.
