A little air shooter fluid in a pci lane

When I was using an air shooter to get the dust out of my pcie lane for some reason it shot a little of its fluid into the pci lane. Luckily the can was far away from the pci lane, and the motherboard was unpowered and unplugged. Would it be best to just leave it like that for a couple of hours or something so the fluid can evaporate?

that is what the can looked like, but not the actual can
