The most effective way to whiten your tile grout is with a simple homemade grout cleaner made of 4 ingredients. If your tile floors were installed with white grout, there is a good chance that it is stained with dirt. Using household products that are usually stocked in your kitchen, you can whiten your tile grout without any chemicals!

I first used this solution on the tile floors in the mudroom of our last Denver home and the transformation was epic.

Our new home has three retro bathrooms with the original tiles. I breathed new life into the master bathroom shower and floor tiles by whitening the grout with this baking soda and vinegar solution!

Slowly add water to create a paste-like consistency. I did not do any measurements, I just eyeballed it.

When the baking soda paste is finished, you have the option to add a few drops of Dawn dish soap for an extra kick. Mix it together with the baking soda paste.

Fill the spray bottle with vinegar. You don’t need to fill the entire bottle, just enough for the surface you are cleaning.

Step 2 | Spray Grout with Vinegar

Spray a section of the tiles and grout with vinegar and let it sit for 1-2 minutes.

Step 3 | Scrub Grout with Baking Soda Paste

Dip your toothbrush into the baking soda paste and with a small scoop, begin scrubbing the grout on the vinegar-soaked section of the tiles. I worked my way from the top to the bottom of the enclosure.

Step 4 | Rinse Away the Solution

For the floors, take a damp rag and wipe up the dirt and baking soda remnants. Repeat these steps until you have cleaned the entire surface. Here is the floor afterward. The image below shows the floors when they were still a little damp, the grout lightened up even more once it was completely dry.
