Unhappy white powder substance build up from battery

I notice after a couple of weeks of turning on my car that it started to have a white powdery substance on the top of the horn brackets in the engine Bay. I washed it off and removed both horns. A week went buy and it didn't appear there anymore(the car had been started 2 to 3 times). When i went to attach sump grill underneath the car a few weeks later I noticed that the bottom of the sump had this white powdery substance built up on it.

Ive seen this powdery substance around battery terminals.

Just wondering if any body's has had this problem and how and if they fixed it?

my thoughts
- maybe earth wire on car isn't touching bare metal (scratch of paint around this area)
- not a good enough connection between stater motor and battery terminal

Clean all grounds and maybe add another ground wire from engine to frame. Use a dielectric grease at the connections.

ground = earth

Good luck!

I realize this is an old post and you surely took care of it but if it's battery acid corrosion a bit of baking soda and water in a spray bottle will take care of neutralizing it.
