Kerosene, mineral spirits, or any solvent that says it contains petroleum distillates WILL leave a residue....
Grease is also a "petroleum distillate" and is fully compatible with any minor residue that kerosene or mineral spirits leave behind. There is no need or value to scrubbing the bearings with alcohol, acetone or anything else. The only residue you must avoid is water.
Electrical contacts have much different cleaning requirments than bicycle bearings so the comparison isn't valid.
