Pinterest Tested: Grout Cleaner

Nothing like the in-laws coming to town to motivate me to get my house squeaky clean. I noticed a few weeks ago that the 50 year old white grout in my bathroom was looking pretty dingy. I knew it was the perfect time to test a PIN I had seen a while back. The photo was pretty impressive, so I thought I’d give it a try.
Homemade Grout Cleaner
7 cups water
1/2 cup baking soda
1/3 cup lemon juice
1/4 cup vinegar
Mix all ingredients together in a spray bottle (watch out—it foams!). Spray on the stained grout. Let it sit for an hour or two. Use a scrub brush to wipe away the dirt.
How did it work? Great! Here’s what my floor looked like:

I loved this cleaner. I hardly had to scrub at a ll. There was little-to-no smell. It was a non-toxic, kid-friendly cleaner. I got it on my hands and didn’t have to worry about chemical burns. The ingredients are all inexpensive and I had them all on hand already. And most importantly, my grout is white again! Yippee!


  1. Can you use it on marble tiled shower or bath floor? Same with the tub cleaner, I don’t know if it could be used on natural stone. There are some things you can’t use on them I trying to get all 9 bathrooms in our bed and breakfast ship shape to sell it. I have been ill, so things got behind a bit. Only family has stayed in our rooms of late. 🙂

    • I would use extreme caution on materials like natural stone and marble. Marble etches easily and I believe the vinegar in this recipe would ruin natural stone.
