I did mine over concrete and it made rust, but I was able to remove the rust later from the concrete!

Be very careful not to over spray in the battery compartment. Usually there are many electronic controllers located in these compartments, and if they get watered, they will short out. Like the aforementioned posts....remove batteries, or flood and wipe

a lot of good info here. Purple protector stuff? what are the ratios for baking soda and h20 mix and baking soda & vinegar? If I may ask.

My choice is baking soda and vineager on the on the terminals. Let it do it's
thing and hose the area down afterwards. Usually spray with WD40 after.works for us.
Sometimes we over think things.

I have removed the rust color from concrete, but it's a chore. I would not pressure wash as noted above it can hit the exterior paint and do damage, why do I know? guess!

I have 6 batteries in my compartment. I use a hose with low pressure/flow and flood the batteries and the tray. Then I pour baking soda on the batteries and the areas of the tray i can get to. Wait 30 minutes and wash down the whole thing. Coach now 10 years old, tray and batteries look new. When the batteries dry I spray the terminals with purple protector stuff, that's it.

Just use a water hose to wash any acid off batteries.

Thanks for the tips guys I'll put my press washer away.

Old trick for top post batteries is put a penny next to each post,costly I know ,but it will keep your posts "green gunk" free.

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.

I would wait for a warm day for fast dry time.

good point. I was assuming the batteries were already taken out and the compartment is empty..:B
