Pressure washing the batt compartment

What kind of batteries? I can (and have) power washed my AGM's and my sealed gel cells but I would be concerned about a wet cell battery bank. I don't pay much attention to my AGM's these days as they are in a separate compartment but I wash my starting batteries on a regular basis. I also periodically (once a year or so) remove the brass nuts, clean, and reinstall. I use no special sprays or compounds but it things go sideways for some reason I so use some baking soda and water to clean up all of my connections. This is generally unnecessary with sealed batteries but needed more frequently with wet cells.
