Add all ingredients to a squeezable bottle or small mixing bowl.
Shake well or until all ingredients are mixed together. There shouldn’t be any clumps.
Squeeze the DIY Grout Cleaner on grout or tile. If you don’t have a squeezable bottle, just use a small spoon to coat the grout. Let sit for 5-10 minutes.
Use a soft sponge, cleaning brush, or old toothbrush to clean the grout.
Dip a soft sponge or microfiber cloth in water, and wipe away the Grout Cleaner.
For hard stains, you can repeat this process and let sit for another 5-10 minutes before wiping away the cleaner.
