My blower was doing the "low speed chirp" so I took it out. I figured it was chirping because the bearings were dirty. So, I literally dunked it in a bucket full of soapy water and spun it around a bit. Lots of crap was left in the water. Let it sit in the sun and dry a bit, reinstalled and ran it for a little while so it could heat up and let all the moisture evaporate.

The reason I didn't try lubing was because, like others mentioned above, it would only attract more dirt.

It was already making noise, so I planned to replace it anyway. But why not try cleaning it first? If the water fried it I would have shrugged and moved on. As of now the blower is whisper silent. Might be worth a shot. Dunk at your own risk though.
