I’m always a bit surprised when ‘miracle’ cleaning supplies actually work. Perhaps it’s from being jaded from being exposed to too many infomercials as a kid. I picked up some Folex Instant Carpet Spot Remover recently, and when I tried it on a month old stain, it actually worked. That was a pleasant surprise.
Footnote: curiousity sent me to Google Groups. Looks like Folex is well known and generally recommended. Now, about cleaning those venetian blinds…
