Iron Out Carpet Stains

Pinterest got me again!!
I was looking through Pinterest on household tips and I came across a tip to get carpet stains up. I even snapped some before and afters of my experience with this.
We bought a cheap iron for $6 at Walmart and some white cloths. You mix 1/2 and 1/2 ammonia and water. The ammonia ended up being too strong for me so I used Vinegar. Spray the stain liberally with the mixture, lay the white cloth over it and iron the stain with the iron set on steam. After a few sprays and irons this is what I got.

I have to say I was very pleased with the results and went about ironing stains out of my carpet all day. That real dark stain had been in my carpet for months.
