I have a white power(LOT OF IT) on the strap buckle holding the batteries in place, I cleaned it once but is back. How do I get rid/prevent it.

You can get battery cleaner spray at Autozone or the automotive isle of many
dept stores. Baking soda mixed with water applied with an old paint brush will
also neutralize the corrosion.
If your batteries are located where you can flush the tops with water, that
is a big help. Wear old clothes!! As you may already know, just one tiny crumb of
the battery corrosion on your clothes will result in holes!
OTOH some folks pay extra for jeans with just those types of holes in them!!

Clean them, flush them, clean them again.
Painting the buckle strap with a good quality paint like Rustolemum will help
also. Bare metal around batteries is going to corrode.
Paint can slow it down but it's gotta be pretty clean first.

Good Luck!

My experience with corroded battery terminal causes has been failing battery and/or loose connections.

Remove cables, clean with round file and wire brush. Apply specific anti-corrusion substance or Vasoline and re-attach. A shot of WD-40 now and then is also a deterant to corrosion.

I had the same problem with my coach. I ordered several Battery Mats (Acid Neutralizing Mat: and placed them under the bottom band of batteries covering the entire bottom of the compartment after I cleaned off the corrosion. I also put 1.5 oz of mineral oil in each cell of the battery. I not longer have the problem.

In the past I used marine grease on the terminals. Never corroded again for years. My car dealership put some kind of red colored grease when I purchased my new vehicle and no problems as well. Wd40 will work as well just doesnt last as long
