Muriatic acid is also known as hydrochloric acid. This chemical can be purchased from pool supply stores and home improvement stores and is used to clean pools and remove stains from concrete. Muriatic acid is a hazardous chemical and should not be poured down a drain unless it has been properly neutralised.

  1. 1

    Wear safety goggles and protective clothing, including rubber gloves. This will help protect you from the acid if it bubbles over the container or spills.

  2. 2

    Slowly add the baking soda to the container of muriatic acid or sprinkle it onto the acid spill. Avoid pouring the baking soda in quickly as it will cause the acid to foam up, which could be dangerous.

  3. 3

    Continue to add small amounts of baking soda until the acid stops foaming. This indicates that the acid has been neutralised.

  4. 4

    Pour the neutralised acid down the drain to dispose of it. If you are neutralising a spill, you can now rinse away the acid safely with cool water.

Tips and warnings

  • Be extremely careful when handling muriatic acid, as it can cause burns and is harmful if inhaled, swallowed or touched.
