Cleaning Grout with Vinegar

I'm totally embarrassed to show you this, but here it is... a mildew or mold spot on the grout in my shower.

I have had the hardest time trying to get it out. I've used my normal bathroom cleaner and bleach. Nothing has worked so I decided it was time to bring out my secret weapon... the vinegar. Mr.Perfect says I'm obsessed with vinegar. Maybe? I just love that I can feel comfortable using it because it's not toxic and it won't stain my clothes.

Here's another picture of the infamous spot that won't go away.

I poured about an inch of white vinegar in a measuring cup with an old tooth brush.

Next, I started to scrub that horrible spot with the vinegar covered toothbrush.

And scrubbed... and scrubbed until....

it started to go away.

And soon I noticed that it was almost gone.

At this point I was yelling down the stairs to Mr.Perfect that the vinegar had removed the spot.

Then I hear Mr.Perfect yell back,
"OK crazy Vinegar Lady!"

Well done Vinegar, well done!
