I have to brag about the fantastic carpet cleaner I found.
This was my carpet this morning, after the boys got fresh black shoe polish on it (!) and after I spritzed the cleaner on it.
This is the carpet cleaner I used - spritz on, wait 30 seconds and then dab off.
This is my carpet after.
I love it! It's like a miracle product. I can't remember where I bought it, but Google "Chem Dry Stain Extinguisher" and I'm sure you'll find a place to buy it. It's invaluable, especially when you have kids in the house!
