Flush points and frame saver

Hey all! With the snow and salt finally gone, I’m looking at flushing my frame and trying to insure all the nastiness of winter is gone. Anyone know of a good spot to shove the hose or whatever. Literally anything, small spots, hard to reach, any known common areas to help get rid of any remaining corrosives. Also looking to get some good chassis saver stuff, and salt removal sprays. Honestly just flood it with whatever you think works. Trying to get an idea so I can get it all done before it gets too hot outside.
