Rediscovered a bucket of pickle from my first time tanning sitting around. It's been there for a very long while- i pulled out a LOT of salt/citric acid (presumably) crystals beforehand. It's only maybe a gallon or two but it's incredibly acidic. I've been trying to neutralize it by pouring in baking soda, waiting, checking pH then pouring in more as needed but ive used my entire bag and it's only raised from about a 1.5 to maybe 3.5. I just want to be able to dispose of this stuff but it's eating baking soda for breakfast- is there something I'm missing or is this normal?
