ALWAYS put any cleaner (whatever type) on the cloth/tissue.......
NEVER ON THE SCREEN.
Personally, I rarely use anything other than a good
"HUHhhhhhhhhhh" (like you're fogging a window) and then rub gently with my shirt-tail, kleenex, TP.......whatever is handy.
The few times I've found something really stubborn, I've used an
alcohol prep pad squeezed till it's no longer dripping.
