I remembered pinning some grout cleaner on one of my pinterest boards, and since I had time, I decided I would try it out.
The original "recipe" called for ammonia, but I didn't have any, so I just skipped it. On the website of
the original pin, it has the original formula and also a halved and quartered version. Since my bathroom was pretty small, I used the quartered version:
1 3/4 cup water
2 Tbsp baking soda
1 Tbsp + 1 tsp ammonia (I didn't have any, so I left this out of mine)
1 Tbsp vinegar
I mixed the ingredients in my spray bottle and found an old toothbrush that I would use to scrub the grout (they make grout brushes for this purpose, but I didn't have one). I sprayed some of the cleaning mixture on to the grout lines and let it sit for a few seconds and then started scrubbing away with my toothbrush.
After I scrubbed one row, I wiped it away with a clean towel. And boy was I impressed! My grout lines weren't perfectly clean, but they were wayyyyy better than before! It didn't take me too long too complete my entire bathroom: probably only 30-45 minutes.
Here are some before and after shots of my bathroom floor tiles:
The top half has been cleaned and the bottom half has not...you can really see the difference!
Now every time I'm in the bathroom, I stare at the floor in amazement of the clean grout (is that weird?). I'm hoping to do this on kitchen tile grout this weekend if I have time. I think my kitchen grout lines are more dirty than my bathroom was, so I can't wait to see the results when I finish!
