vinegar is about a 3. milk is about a 6.5. However, values can very by 0.5 or so. The only exact way is to eventually get some ph 4.0 and 7.0 (or 10.0).

distilled water will actually change in PH when exposed to air. It can go down to 5.5 range, just a heads up.

you get a bottle of water & pop it open it will not sway in ph within the that time frame. I know some people may have different methods of storing water but I only drink bottled & it will not change ph in the time it takes to test ph / calibrate. I am not sure if it differs from state to state, but my purified water has always been 6.9-7.1 & I am sure my meter was to blame for being off 1 point those times it was not 7.

Thanks for the info, I tested some white distilled vinegar and it came out around 3.1, saved me from having to buy the solutions for right now.
