I have been using it in my locations. Also printed up big posters saying the games are sprayed with it. It does leave a film on the machines (my guess is this was the active killing agent that is reactivated). I spray the games everywhere someone might touch routinely (buttons, start button, coin door, ect) let it set 2 minuets then wipe it off with a clean rag. I then remove the lock down bar, clean the glass with regular cleaner, and wipe under the lock down bar as i have found the biocide will run down underneath it.
I will say it also cleans really well, my towel was black/dirty after scrubbing the machines down with it.
