I have some brushes (brushes for shaving--I'm a barber) with wood handles
that I need to sterilize in a pressure cooker (autoclave) on a regular
basis. Is there a wood preservative product that will protect the wood
from the steam?
There are coatings and finishes that may help, like epoxy, but how do you
get it around the bristles? It is not just the handle but the base also.
Wood is not allowed in any area that I know of that must be sterile. Check
the knives of your local butcher and they will be plastic handles.
And check your good knife handles if you run them through the dishwasher. True,
part of that is chemical action of the detergent, but part is also the very hot
water. IIRC, it takes about 6 to 8 passes to remove the finish and start
turning the wood to something nasty.

Soaking them in oil from time to time seems to keep them pretty happy
though. I've started soaking the knives in vegetable oil (because it's
there, not because it's ideal) and it seems to have helped considerably. I
soak them whenever they start to get white looking.

Can't do it. Wood loves water, expands when it gets it. Finish doesn't.
Then there's the rules on what may be considered sterile. Seems barbers
always use the UV boxes. Not sure what "stylists" use, 'cause I refuse to
pay double the haircut price.
I doubt it. Repeated steaming of wood will weaken it, although there
are some kinds of woods that will hold up better than others. I'd
replace the brushes with ones that have metal handles. I'd think
placing the brushes in a dry 180-degree oven for an hour or dipping
them in 91% alcohol would kill any (harmful) living thing.
