Can I use baking soda to clean oil stains on concrete?
Baking soda is a popular DIY solution for cleaning oil stains on concrete. While it can be effective, it’s essential to note that baking soda alone may not completely remove the stain. The effectiveness of baking soda depends on the type of oil, the age of the stain, and the porousness of the concrete.
For fresh oil spills, baking soda can absorb the oil and help lift it off the surface. Mix baking soda with water to form a paste, and apply it to the stain. Let it sit for about 30 minutes to an hour before rinsing with warm water. For older stains, you may need to repeat the process several times or combine it with other cleaning agents to achieve the desired result.
How do I mix baking soda with water to clean concrete?
To create a paste for cleaning concrete, mix 1 cup of baking soda with 1 cup of warm water. Stir the mixture until it forms a smooth, thick paste.
