Please help! I made fizzy bath salt last weekend (1/2 cup epsom salt, 1/4 cup baking soda, 1/8 cup citric acid, WSP bath bomb powder, 8 drops of EO). I used it yesterday and there was no fizz and it had solidified into a blob (used a spoon to scoop it out). It was stored immediately in a glass jar with a tight lid after I made it. Any advice is greatly appreciated!
