Is citric acid better?
I believe at this time that citric acid is the most effective, and we need more data. Mix the citric acid 1 to 10 with water. That’s a 10% citric acid solution. One way to make it is to use a level tablespoon full of citric acid in a glass and then add 9 tablespoonfuls of water. When using this 10% citric acid solution, use 5 drops for each one drop of MMS.
