Genny asked: Hi, I am wondering if there is something I can use to remove grass stains from my sidewalk. My grass looks beautiful, and the sidewalk bright and white, except where I ran over it with the lawn mower, green wheel marks up and down the sidewalk – very unsightly. Thanks in advance.

Grass stains show up everywhere, on shoes, clothes and even sidewalks. Fortunately, they can be removed with a little scrubbing and the right cleaners. Follow the guidelines below to get your sidewalks looking white and bright again.

Removing Mild Grass Stains

You Will Need:

  • Washing soda or detergent (do not use soap)
  • Water
  • Bucket
  • Scrub brush or stiff broom (depending on size of stain)

Steps to Remove the Stains:

  1. Begin by sweeping away any loose grass or dirt.
  2. Combine the washing soda or detergent with water in the bucket.
  3. Pour some of the sudsy water on top of the stained area.
  4. Scrub smaller areas with a scrub brush. For larger areas, it will be helpful to utilize a sturdy broom with stiff bristles to scrub.
  5. Apply more washing soda/detergent as needed and scrub until the stain is removed.
  6. Rinse thoroughly with clean water.
  7. Allow to dry completely.

Removing Heavy Grass Stains

You Will Need:

  • Glycerin
  • Washing soda
  • Borax
  • Water
  • Bucket
  • Old clean cloths
  • Scrub brush or stiff broom (depending on size of stain)

Steps to Remove the Stains:

  1. Begin by sweeping away any loose grass or dirt.
  2. Moisten a cloth with glycerin and moisten the entire stained area.
  3. Gently rub the glycerin into the stain.
  4. Next, fill a bucket with one gallon of water, ¼ cup of washing soda and ¼ cup of borax.
  5. Pour some of the sudsy mixture on top of the stained area.
  6. Scrub smaller areas with a scrub brush. For larger areas, it will be helpful to utilize a sturdy broom with stiff bristles to scrub.
  7. Continue to scrub, cleaning your brush/broom as needed. It may be necessary to empty the bucket after a good amount of scrubbing and continue with fresh.
  8. When all the stain is removed, rinse thoroughly with clean water.
  9. Allow to dry completely.

Additional Tips and Ideas

    Took a while, but thanks for your suggestion. Parked the new riding mower on the new concrete. All the junk (molten grass, etc.) dropped on large patch. Will try the suggestions.
