Vinegar (containing C4H4O2, solution PH typically 2 - 3) and baking soda (NaHCO3, PH typically 8.1 – 8.6) are traditional, readily available, and cheap.
It’s often handy to increase PH (decrease acidity) with “buffering” agents, such as solid wood or charcoal washed in the solution. This can limit acidity (low PH) without producing excessive alkalinity (high PH), and doesn’t require PH to be measured first.
