Excessive battery terminal corrosion

What else can you recommend? I tried the anti-corrosive spray and I believe it's worse than before. Your opinion please.
Don't think my son's battery got that bad...
Before:
After:
After was still charging.
I did take a wire brush to the hold down and then paint it. The after picture was after a couple of hours of charging. I let the paint dry for 2 hours and I let it charge a bit more as the newest battery Wal*Mart had was, as you see, 9/17.
I failed to get a photo before I removed it, but you can see the residue on the old battery that is indicative of the state. I believe it was ~5 years old when removed.

I grease the terminal post and then smear the clamps with whatever I have on hand. A old trick I learned at the dealership.
My parent's van even with a PCM-controlled alternator will cause batteries to outgas and spray out acid mist - Toyota was starting to phase that in. That van gets a quick spray and hose down every year. It's seen only Costco batteries, the OEM one was replaced by a group 35 Kirkland and then with a 24F.

I think we have a new "Best Of":
Um. Wow. New battery and new cables pronto. Pull that battery and wash everything down with a baking soda solution. Check the voltage regulator because that battery is gassing like crazy and it’s probably from over-volting
I didn't read all 4 pages so if someone posted this I am agreeing. Check the alternator/voltage regulator for overcharging.
