  2. 2

    Plug the drain

    Pull up on the stopper or install the drain cover. For combination strainer/covers, close the strainer so no water flows through.


    If your drain cover is missing, you can make one using plastic wrap and a saucer. Lay a large square of plastic wrap over the drain, then set the saucer over the plastic wrap to seal the drain.

  3. 3

    Mix the bleach and water solution

    Use the measuring cup to add 1 gallon of cool water to the sink, then add 1/3 cup Clorox® Disinfecting Bleach


    You can mix the solution in a plastic bucket if you prefer. This is a good option when cleaning multiple sinks at the same time.

  4. 4

    Wipe sink surfaces

    Use the scrubber sponge to wipe the sink bowl and the fixtures with the bleach and water solution. Re-wipe as needed to keep surfaces wet for 6 minutes to disinfect.

  5. 5

    Drain and rinse

    Remove the drain cover and allow the bleach solution to drain away. Rinse the sponge with clean water before using it to wipe the sink and fixtures with clean water.
