I agree .... the high-pressure water can blow the grease out of the bearing housing so the bearings just grind themselves to nothing. Yes, bearings, loose or cartridge, can be replaced ... but doing something that harms the bike because you can fix it later ... we all make our choices. I do not choose that.
I use Simple Green, but any sort of soap is fine. as was mentioned, if the grease is caked and baked and won't come off with soap and a brush .... maybe time to break down everything and repair and replace in a more serious manner.
