whoa....
I only use WD40 to clean the bike in the Winter!
I found out the hard way, I would never use a Hose to clean. Water and (gunk) will get in your cables, springs of your derailleurs, FREEZE! Course if you want to replace things, LOL kidding
I would wait till warmer weather before using a Hose, Pour water out of a bucket, or do as I do, NO water, just rags and WD40. Then relube.
