Method 2: Using Baking Soda, Ammonia, & Vinegar to Remove Grout

It is one of the most powerful ways I have ever found to remove strong white grout that’s turned black. You can follow the process below if you fail to remove grout in multiple ways.

  1. Fill up 7-cups of warm water in a bucket. Added ¼ cup baking soda and ¼ cup ammonia.
  2. Take an old brush and mix them properly. Keep continued mixing until it becomes mixed properly.
  3. Take a spray bottle and drop the mixer on the bottle. Spray on the affected areas and wait for a minimum of 10-minutes.
  4. After completing all the above steps, you should use a scrub to clean the areas. Use water to get the final result.

To clean grout, you can use cold or hot water in the final stage. Use this process once a time in a month so that the grout doesn’t come out in your kitchen.

Method 3: Try Oxygen Bleach to Remove White Grout Which Turns Black

The process is looked like some of the above processes. Without making any mistakes, you can follow the below guidelines properly.

  • Mixed powdered oxygen bleach and warm water on a spray bottle
  • Spray the affected areas and wait for 15-minutes so that the mixer works properly
  • If you notice that the mixer oxygen and warm water soaked up within 15-minutes, you need to spray some more mixers on the affected areas.
  • Once done, you can use a scrub, old cloth, or a brush to clean the areas and get a clean grout-free area.

Don’t use much Oxygen with warm water because it reflects a lot, and sometimes the affected areas are damaged. Of course, you need to use powdered oxygen bleach to get a better performance.
