My cat likes to sleep on my receiver because it's warm and she must of had a hair ball attack while on top of it. I can see a little residue and a little moisture on the of the vents but the receiver is cycling on/off rapidly. I don't think a lot of liquid got in there (she'll start having a hair ball attack and she'll jump down and go hide under the bed while it's happening.) I've unplugged the receiver and I have a large fan blowing onto it to try to evaporate any liquid. Is there anything else I can do to help it?
