Always warm soapy water and then a rinse off with just the hose end!
That would still do it for bearings TBH. Water tends to sit there in the bearing indent, it’s a pretty inaccessible place for proper cleaning so easier for it to start rusting almost unnoticed.
I don’t mind the occasional jetwash but I’m quite anal about bike maintenance (I actually enjoy it!) and I also treat bearings as disposable items. Not really something to maintain, just take the hit whenever they need replacing. Sometimes you’re lucky and they’ll last 2-3 years, other times you might only get 6 months out of them.
Make sure when you replace them that you use the best quality ones you can get and fit them carefully with coppaslip or waterproof grease, it’ll help minimise creaking/wear etc.
