"The Medway Handyman" gurgled happily,
sounding much like they were saying:

I doubt you could force a significant amount of lubricant out of a
bearing with a 'peanut performance' DIY cold machine if you tried.

No, but you could easily force water in.

I suppose you could if you left the pencil jet in the same place for
half an hour, but in the 2 - 3 mins it takes to wash a wheel, 80% of
which time the fan jet isn't near the bearing anyway.....

Like I said - whether it's feasible is another question entirely.
