Sorry if I gave out bad info. I just posted about my own experience.
I used to find rust inside my wheel bearings after less than a season of riding and was spending a bunch of $ replacing them as insurance against a failure, which would likely happen during the rare instance that I was actually doing well in an enduro.
I don't use a pressure washer on my bike, btw
Since I started (8-9 years ago?) adding more grease I haven't had any failures nor have I found any rust inside when I clean and repack them (with regular Bel-Ray blue grease). I've been getting 3-4 years (1500-2000 mi.) out of a set. ymmv

Fwiw, I ride mostly tight, rocky/technical, often muddy, trails and creek beds so maybe the low speeds don't allow heat to create the problems that you alluded to.
