One method that works well for me is to soak the bearings in Stoddard solvent if you can find it or Mineral Spirits then blow the old chunks of grease off the bearing with air. A small paint brush can aid as well. Do this for a few cycles changing the solvent to a fresh batch after the bearing looks clean.
Resist the urge to "spin" the bearing with the compressed air only move it with your fingers. Make sure to blow the air between the rollers until there is no longer grease coming out from around the grease seal. After the bearing is clean, blow off the bearing really well to dry it off ... then repack the bearing with grease.
