If you've already blotted it, I'm not sure the salt solution will work. I hadn't ever heard of that, and then red wine got spilled on my cream carpet at bunko one night.

One of the girls grabbed my big salt container from the pantry and smothered the big red spot in tons of salt. We let it absorb, then vacuumed it up. It was very faded. After that, we were able to use regular blotting and carpet cleaner to get it the rest of the way out. You can't see it any more, but you can kind of feel a rough spot in the carpet.

Good luck! I will never have cream carpet again - what was I thinking?? Kids, dogs, bunko...
