How to remove red wine from carpet a dry cleaners guide:

1) Get to it sooner than later, a fresh stain is much easier to remove than an old stain
2) Mix 3 parts water to 1 part white vinegar and pour it over the stain
3) Put a clean towel over the stain and iron with steam
4) Repeat until you are happy
5) Treat with hydrogen peroxide to correct any remaining color

The goal here is to use the vinegar to counteract the tannins in wine and the heat from the iron to draw up and transfer the stain solution mixture (water and vinegar) into the towel.

I hope this helps Happy cleaning
