Use only 91% or higher alcohol. Anything less has too much water content. Remove bearing shields,(very critical step) Place bearings in a gatorade bottle with the alcohol and shake to oblivion. Empty and replace the alcohol and repeat. Then use compressed air or a hair dryer (don't blow with mouth, too much moisture) and completely dry the bearings. Then apply 2 drops of bones speed cream in each bearing and replace seals.
