I soak mine in alcohol for about 5 minutes then I let it dry over night. Only problem with this is that it leaves the atty bone dry the next day, which is good, I guess but it makes it hard for the wick to soak up the juice when I load another cart onto it. So what I did was drop a couple of drops of juice right onto the atty and then put on the cart. That seemed to work fine. Also, I've heard of people removing the paint on their atty using alcohol. I haven't had a problem with it, personally, but it's something to consider. I think it has something to do with how long you soak the atty in the alcohol, which is why I only do it for 5 minutes.
