I tried it on my other HP laptop that had some weird water marks on it that I couldn't take off.

Purchased this product to see if it would help clean it, and apart from a few stubborn marks it more or less made my screen look brand new

This screen cleaner really removes stubborn greasy marks from the flat LED screen, used on 65" it really made it spotless.

I finally tried this one, and with a single spritz and a few circular screen wipes, the nasty mark had disappeared forever from the middle of my LED-cluster

With just a single spritz of this stuff and a quick wipe down my screen looked as clean as it did the day I bought it
