I wonder if anyone has tried the cleanse posted by Katheryn using ct. I'm sure you know c.t. is used in cooking and I have cleaned copper & brass with it. It is an acid powder (potassium bitartrate) or potassium hydrogen tartrate. It is also used in some baking pwd. The only natural source is grapes and I don't know if there is a snythetic source. What I want to know is what effect does it have on stones and has anyone used it for a cleanse and passed stones? Thanks.
