Okay, before you judge me for having black grout, let me clarify that this is not my kitchen floor. We rent our townhouse and this is what the floor looked like after our most recent renters moved out. If this is what the grout looks like, you can imagine what the rest of the place looks like. Pinterest to the rescue!
- 1/2 cup baking soda
- 1/3 cup household ammonia
- 1/4 cup white vinegar
- 7 cups warm water
1. Combine ingredients in a gallon container starting with the water.
2. Shake mixture well, then pour into spray bottle.
3. Spray on grout and wipe with a towel or scrub brush.
Do not use this with bleach!
Note: This makes 8 1/2 cups so I suggest cutting it half if you want just enough to fill a spray bottle.
I was pretty impressed with this stuff. What I wasn’t impressed with was the fancy grout sponge that I thought would be great to clean the floor with. It wasn’t. Don’t waste your money.
I switched to a rag because I didn’t have a scrub brush with me, and I was surprised by how well the rag worked. A scrub brush would definitely be your best bet though. The grout on this floor is a darker color to begin with, so you won’t see the stark contrast between clean white grout and nasty black gunk, but you get the idea. This stuff works! The left side is before and the right is after.
