Touch Screen

I have Windows 10. They tell me that Win10 is touchscreen enabled. But I have been trying to play chess by touching my screen and all I get are fingerprints on my screen! And this is not pretty because I eat a lot of greasy food and now my screen is so filled with grease that I can bearly see the chessboard. Can someone help me? I am a paying member and I submitted this question to staff but they just laughed at me. 

I had same problem but solved it like this:

Game 1: use fingers

Game 2: use tongue

Game 3: use fingers

Game 4: use tongue

And so on. It never gets really greasy that way.

You need to use Sharpie permanent markers to enable the Touch Screen abillity of your Windows 10.
