After reading about Folex on here I got some a couple months ago. I used it in our living room where there was a light stain that we suspect was soda pop that someone neglected to tell us about at a party. The stain had been there for a couple of years, and after some Resolve and a few steam cleanings had gotten pretty light where you only saw it during the day in good sunlight. Well that stupid Folex made me second guess my decision to use it because it made the stain worse. My only thought is that the Folex had drawn up the soda that had made it's way to the bottom of the carpet because it wasn't discoloring the carpet, but every time the paper towel I used would be light brown (I'm guessing Pepsi or Coke). Finally after about 8 applications the stain is pretty much gone.
