dish soap. If you are cleaning in a small apartment without a big sink, a 16-quart storage bin works nicely for most pedestal fan blades. If your fan is small, even a clean bathtub can work in a pinch, though I put down a towel first to prevent scratches.
For especially busy families, I suggest making this a “set it and forget it” chore: start the soak after breakfast, wipe the blades down while lunch is cooking, and reassemble in the afternoon. It is the kind of job that fits
