I use whatever alcohol I can find(preferably 91 to 99).
I put the bearings in a good quality Ultrasonic jewelry cleaning rig.
When the timer goes off(about 10 minutes) I lay the bearings down on a few paper towels.
I use a hair dryer to dry the bearings(doesn’t take long.
Then, I lightly press each bearing onto the tip of a standard wooden pencil.
I put one drop of thin lube(synthetic/non petroleum) into the bearing.
Then I hold the pencil firmly in one hand and use the thumb on my other hand to flick the bearing several times to get most but not all of the lube out. Even a very light coating of lube will not drag down spin time and the bearing will last longer.
