How to Clean Stainless Steel Water Tanks

Mark O'Brien

Stainless steel water tanks provide a phenomenal way to store safe drinking water or to provide animals with a constant water source. Over time bacteria in the water can cause algae and various "floaters" in to appear. It is always a good practice to clean your stainless steel water tanks well and then treat them as needed.

  1. Unscrew the drain plug on the stainless steel water tank. Allow the dirty water to run out.

  2. Mix 10 parts water to one part bleach in a bucket.

  3. Scrub the side walls of the stainless steel tank with a rag soaked in the bleach mixture.

  4. Pour the remaining solution into the tank and allow it to run out of the drain hole to clean it.

  5. Rinse the tank out thoroughly with water. Screw the tank drain plug back in tightly. Fill the tank up with water.

  6. Tip

    As the water begins to form algae or even a smell, shock the water with a 50 ppm chlorine tablet. Use the tablets as needed throughout the year as they are safe in water consumption.


    Wear rubber gloves and safety glasses.
