So I was constantly having to clean and put corrosion resistant grease on the battery terminals to keep them from corroding, and I started to do some research. I found that alternators, putting out high amperage, could cause the corrosion. I tested it and it was over 15 which is definitely high. So I swapped alternator and cleaned it again, and now it's pretty fine.
