I have two of those magic fans that sit on the wood stove & just spin for no apparent reason. Anyway, they have slowed down in recent days. They were barely spinning even when the stove was running full bore. I removed the electric motors, soaked them in a shot glass full of gas line antifreeze (methyl hydrate) for about 5 hours. They runs supper fast again, even on a cool stove. I suppose isopropyl or rubbing alcohol might work better as they have a lubricant mixed in.
Edit: I forgot to mention I put a dab of 3 in 1 oil on the shaft as well.
