I soak all my bearing in White Lightening, its a Chain lube for Bikes. It has Teflon in the mix. When it dries out the teflon is left. It works really well for me, because it doesn't attract dirt. I'll clean them and do this about 4 times. Then never have to touch them again. I did this with my Nitro buggies, until I found the Blue Sealed bearings. With these I never have to touch them from the Get-Go... My Nitro On-Roads I just started using the Blue Sealed bearings, so I'll never have to go through the Clean relube thing again.
If your looking for the Bearings a Guy sells them on EBAY look under "Mugen, Serpent, or Yokomo". I think there called TeamBlueStar???
With the Blue Sealed Bearings, you'll never have to do the Clean/Lube thing again!!!
Keep the Rubber(or Foam)on the Road!!!
