White crusty stuff.

I found a white crusty-like substance on one the battery post to my trailer, so I cleaned it up and reattached the cable. How do I prevent this from happening again? I see where grease is applied to the post and clamp, or in older times, a penny put near it, I guess to draw the corrosion away from the post. I need a better solution. Thanks

    I use a 2 pronged approach to this that was taught to me by a Master Mechanic that was used in their shops for commercial over the road trucks and have been using it for years with very good results and no more white crusty stuff.
    After a good cleaning.

    First put down Battery Terminal Anti Corrosion Washers on each battery post.

    Then apply a good coat of Battery Terminal Protector

    You should be good for years,I know I have been.

    Auto stores have battery terminal corrosion products plus a male/female wire brush. Batteries can vent more with age/usage, consider having them load checked for current state.
