Method 1: How to Make Grout White Again with Baking Soda, Ammonia and Vinegar. Fill a bucket with 7 cups warm water, 1/2 cup baking soda, 1/3 cup ammonia, and 1/4 cup vinegar. Stir to combine. Dip a sponge into the mixture or pour some into a spray bottle.
Baking soda is mildly abrasive so it helps to remove the dirt that is stuck in the porous grout surfaces without causing any damage.
Baking soda is a safe deodorizer, whitener, and household cleaner—and it's an effective natural grout cleaner. Because baking soda is also a mild abrasive, using it for cleaning grout lines gives you extra firepower without the risk of scratching your tile.
Mix 2 parts baking soda and 1 part bleach to make a thick paste. Spread this paste onto the dirty grout and wait 5 to 10 minutes. Scrub the grout using a stiff-bristled brush, then wait another 5 to 10 minutes. Once the time is up, rinse the paste off using water.
Christine Pyne added: “A guaranteed method that I've found is to use baking soda and water. Use the two ingredients to create a paste, making sure that its not too runny and apply it to your grout. “Then leave it for around 15 to 20 minutes and it'll come out whiter than ever.”
Saturate the grout with lemon juice, a mild disinfectant that gets rid of grout stains naturally. You can also use white vinegar for chemical-free grout cleaning. Simply pour vinegar from the bottle into the cap and pour it over the dirty grout lines. Allow the lemon juice or vinegar to sit for 10 to 15 minutes.
The vinegar combined with the baking soda will create a bubbly reaction, which will get rid of soap scum, limescale and mould. Be sure to work the baking soda into the grout lines, removing all build-up.
Q: What do professionals use to clean grout? A: whether you believe it or not, most professionals use a solution of white vinegar and water with a 1:1 ratio. This solution is often more effective than dedicated Ph-neutral grout cleaners.
Add 1 cup of baking soda and 1 cup of hydrogen peroxide into a bowl. Mix the ingredients thoroughly. Apply the mixture between your shower tiles and let it sit for 10 minutes. Wipe the mixture off and rinse the surface with some water.
Hydrogen Peroxide
Using this is a much better choice than bleach in that it leaves no firm order afterward. Pour a little bit into a spray bottle and spray it onto the contaminated area. Let it soak in for 10 minutes, then scrub.
If you're looking for ways on how to remove baking soda residue from tile, all that you'll need to do is create a vinegar and water solution, or another baking soda solution with vinegar and water. Removing baking soda residue is essentially the same as removing any other substance from grout.
If you know your grout has been sealed but it has accumulated heavy dirt or mild stains, turn to vinegar, that trusty old household staple. Fill a spray bottle with a half-and-half solution of vinegar and warm water. Spray the mixture on the grout, let it stand for 5 minutes, then scrub the surface with a stiff brush.
Use a soft small brush, sponge, or a gentle toothbrush to get into the crevices of the grout. Don't use any hard brushes or anything with harsh metals as this can destroy the grout and loosen your tiles. If you're dealing with stubborn stains after trying soap and water washes, try a pH balanced cleaner.
Did you know that toothpaste makes an effective tile grout cleaner? To remove dirt and grime from tile grout: Dab some white, non-gel toothpaste onto the grout.
To remove everyday dirt and debris, mix two parts baking soda with one part water. For stained or discolored grout, mix two parts baking soda with one part vinegar. And if you have coarse or fragile tiles, mix two parts baking soda with one part hydrogen peroxide.
For stubborn dirt, you can make a paste of baking soda and white vinegar to leave on the grout overnight, and then remove with a spray of water.
The good news is that vinegar will not corrode grout if you have taken the trouble of sealing it regularly. In such a case, vinegar should not cause an issue with the grout since it is sealed.
Grout almost always appears darker when wet than when dry. New grout can take 24 or even 48 hours before it's completely dry. It depends on the humidity and temperature in the room where the grout is installed.
Fill a spray bottle with equal parts distilled white vinegar and warm water. Give it a good shake and then spray the grout. Let it sit for 5 minutes. Once it's absorbed, give your grout a scrub down with your brush.
You can also use a mixture of baking soda and ammonia solutions which can be very useful in removing grime, dirt, and difficult-to-remove dirt. The use of such a mixture is also safe for the tiles.
Assess the Grout
Another way to check if the grout has been sealed is to monitor the water beads. If the water beads flow done from the ground, it is correctly sealed. However, if the grout absorbs the water, either the grout hasn't been sealed or the sealer has worn off.
To bring tiles up with baking or bicarbonate of soda if that's all you have, make a paste of 2-3 cups baking soda and a little water, or sprinkle directly onto the tiles. Scrub it in using an old toothbrush or a sponge to help remove tough stains.
