The spray in the conference room

Does anybody know what the spray (not the one you use to clean the buttons next to the door to the security room, the one next to it) does?

I once saw that Ashley gave it to Mike, when he left to look after Richard, but I never saw him using it.

So is the only purpose these few extra lines or does the spray have any special use later on?
