This product will etch the concrete; that's what it was designed for. It's not a concrete cleaner, and the vapors, even through they're far less than our regular Muriatic Acid puts off, could still be too dangerous to use indoors. If you need to clean the concrete use a concrete cleaner, not Muriatic Acid. If you need to etch the concrete so it will accept a sealer, use a less harsh acid like Klean Strip Phosphoric Prep & Etch.
