It's citrate who is required to solubilize oxalate.
120 ml lemon juice could do the job, mixed with 500 ml water.
The lemon juice has citric acid. Need to mix with baking soda to produce sodium citrate. I mix 16ml lemon juice with 1g baking soda to make sodium citrate. It's sodium though, but I don't mind as it's the citrate I want.
I had a bad experience with using industrially made potassium citrate. It is made by black molds. See haidut's thread on RPF.
Soon after that thread was started, I developed a really bad infection and when I recovered, I went back to my logs and realized I had taken potassium citrate for increasing by blood flow (via increasing zeta-value) and I had also unintentionally taken it while I was using tetracycline to treat infection causing my high BP.
I connected the dots and realized that the trace of aspergillus from the potassium citrate made the cell wall deficient bacteria (morphed from using tetracycline) morphed further into a more virulent fungal parasites.
Since then, I have been very cautious about using industrially made potassium citrate.
