said by CylonRed:No - it is not the same: "Prepares concrete for painting and staining. Citric acid powder is safer than muriatic acid"
Chemicals can have many different and perfectly acceptable uses. I have muriatic acid that I bought at Lowes that's labeled for etching concrete -- that I use in our swimming pool to lower the pH level. I have phosphoric acid here at work that's for cleaning concrete, stone, etc that we use for cleaning stainless steel (per our chemist's recommendation).
