How to Change Grout Color, the easy way!


There are tons of recipes out there for homemade grout cleaner, but I wanted an effective one that wasn’t too hard to make. I ended up with this grout cleaner recipe which only has 2 ingredients, and it worked great!

Homemade Grout Cleaner

  • 30 minutes (time spent doing stuff)
  • 15 minutes (time spent waiting around)
  • 45 minutes (total project time)
  • Tools
  • a scrub brush or an old toothbrush (this DIY scrub brush for your drill works great; let the drill do all the scrubbing work!)
  • rubber gloves
  • respirator
  • safety glasses
  • Materials
  • 3/4 C baking soda
  • 1/4 C bleach


This is what the grout looked like when we moved in. Gross!!!

Mix the baking soda and bleach together in the bowl until it forms a thick paste. Apply the paste to the dirty grout lines and let it sit for 30 minutes.

The bleach will do most of the work just sitting there, but after 10-15 minutes, scrub it with your scrub brush to really work the cleaner deeper into the grout.

Wait another 10-15 minutes and then rinse the cleaner off. If you have a handheld shower head, use that; otherwise just use a damp rag and rinse it out often as you wipe the cleaner away.

Remember, grout does sometimes turn darker when it’s wet. So if you’re not totally impressed with how sparkling white your grout is right when you finish rinsing it, wait a few hours until it dries!

I am so happy with how CLEAN everything is now!

Just a few important notes:

  1. You’re using bleach. Make sure you are wearing old clothes or something you don’t care about. I figured it wouldn’t splatter so I didn’t change before doing this, and now my jeans have white spots all over them! There is a surprising amount of splatter, even if you’re careful. So just change first.
  2. Wear rubber gloves to protect your hands from irritation.
  3. Open a window or wear a respirator to protect your nose, mouth, and lungs.
  4. Wear safety glasses to protect your eyes from irritation.
  5. And if you use a washcloth or rag to wipe the cleaner off, make sure it’s something that’s okay to be bleached.
