Using a Hanna ph tester (digital readout) what would be the reading if I checked battery acid? :?: It's supposed to be 33% acid, and the rest being water.

Okay, I'm going off the top of my head, but 33% sulphuric acid is probably going to be around 0.3 pH. I'll look up the Kpa, but the take home lesson is that your wash shouldn't be anywhere near that low...
