8 powerful ways to clean dirty grout naturally

If you have a mold problem in your grout, say in the bathroom, this is the solution you’re looking for. You should take 1 part hydrogen peroxide (3 percent) and 1 part water, and combine in a spray bottle. Spray over the grout and let it sit for about 45 minutes to an hour. After that rinse it and reveal clean grout.
4. Salt
Salt has antibacterial properties, so it’s great for disinfecting, cleaning and scrubbing that stubbornly dark grout. In fact, the salt will literally suck the water out of the mold and kill it all together. Simply rub it into the grout with a damp cloth, let it sit overnight and then next day, you’ll smile to see your see your grout looking good!

5. Citric acid
You’re probably already aware that citric acid helps lighten things–like when it’s used in beauty products to help fade dark spots. Well, you can use it for your dirty grout, too. The acid will kill off any mold and mildew, but if you really want to get a clean look, mix it with some baking soda when you rub it in.

6. Borax
Borax works similarly to baking soda in that it cleans, disinfects and deodorizes. So, use some of this natural mineral product like you would baking soda–rubbing it into the grout with a damp cloth–to make it look good as new.
7. Steam clean
Now, steam cleaning won’t lighten your dirty grout, but it will disinfect it and loosen any dirt that’s gotten trapped. This is the ideal all-natural solution to help get rid of germs and mold, and it’s easier to use any of the lightening or cleaning solutions above.
8. Liquid castile soap
This all-natural soap is made from plants, so you don’t have to worry about harsh chemicals here. Use the liquid version mixed with water and baking soda to disinfect and lighten up your grout. This is a great all-purpose investment you can use to clean many parts of your home.
