Updated April 17, 2017

All summer long, you take care of your plants by watering them and ridding them of any pests that may want to stay. When you move your plant, you find underneath the pots are water stains on your concrete floor. A power washer will help remove the stains, but many people do not have one of those. Using a home remedy not only saves you money, but also is more earth friendly.

  1. Wash the area with water and scrub the stains with a brush. This may remove the stain. If it does not, proceed to the next step.

  2. Pour liquid dish soap or sprinkle dry detergent on the stain. Allow this to stand for five to ten minutes. Pour on some hot water and scrub the stain away with a hard bristled brush. Be careful not burn yourself with the hot water. You may have to do this several times if the stain is stubborn. If this does not work, proceed to the next step.

  3. Pour straight vinegar onto the stain and leave it to penetrate the area for an hour or two. Add more vinegar if necessary so the area does not dry out. Using a brush, scrub the stain away. You may have to do this several times. If your stain is still there, proceed to the next step.

  4. Mix 1 part oxygenated bleach with 2 parts hot water. Pour this solution on the stain and allow it to penetrate for five to ten minutes. With a brush and hot water, scrub the area. Repeat if necessary. If this fails, continue to the next step.

  5. Mix 1 cup of trisodium phosphate with 1 gallon of water. Pour this solution over the stain and leave it to work for 15 to 20 minutes. With a brush and hot water, scrub the stained area. Repeating the procedure if necessary.

  6. Tip

    If none of these methods work, you may have to hire a professional cleaner to do the job. To prevent water from staining your concrete floor in the future, place your pots in a container or saucer that will catch the water. Be sure to have some pebbles or something similar in the bottom of the container so your plant will not sit in water and rot.


    If using vinegar, do not spill any on your plants. Vinegar can kill them. If using bleach or trisodium phosphate, keep kids and pets away from the area. Use rubber gloves when scrubbing the stains to protect your hands.
