Chain Lube Saves The WD-40

So, OK, I was watching Diff'rent Strokes and suddenly my AC starts squealing again. WD-40 only lasts a short while. It's great for loosening something, but it's the Fargle Blork as a permanent lubricant. So I took my can of chain lube (Did I mention I drive a motorcycle?) and sprayed it where I had sprayed the WD. The fan started right back up. Now I have to figure out how to clean chain-lube out of the cooling vanes.
