Found an online article that says you can convert Baking Soda to washing soda this way:
pour baking soda onto a cookie sheet or glass pan, spread it out very thin
Heat in the oven at 400 degrees for 15 minutes
remove it, give it a good stir around
Bake another 15 minutes
take it out let it cool...boom PH UP
I might try that tonight..I have some baking soda I don't need but do need about 1 cup of ph up/washing soda
to get my ph at 7.5 (accidentally put too much acid in...sitting at 7.2 temporarily )
