I have an RO system which I don’t think has been cleaned in many years and I would like to give it a clean. I have read an article from this forum which recommends cleaning using citric acid and then an alkaline cleaner followed by a clean with peroxide. I would like to use this sequence on our system but unfortunately the article didn’t mention the concentrations of the chemicals. I have a concentration for the peroxide solution but not for the others.
If anyone would have any information on concentrations I would love to hear them.
