I tried and tested this simple trick to clean and remove spilt red wine from your carpet. The biggest mistake most people make when trying to remove a spill from their carpet is rubbing on the spot with a rag or paper towel. The only thing this will do is to push it further into the carpet, and it may penetrate the fibers down into the dye site. This is a problem, because the majority of carpets used in residential homes are made of nylon.
The problem with red wine, which makes it even trickier is that it contains dye naturally. Blotting the spill (which is what you should usually do on any spill) does not always remove all the red wine. Now what I found as a good way to remove red wine, is to cover the spill with corn starch (which you’ll find at your local supermarket). You need to push the corn starch down into the carpet, all the way to the bottom of the carpet, using your hands or feet.
Now you need to leave it like this for at least 24 hours. During this period, the corn starch will absorb all the red wine. After 24 hours, vacuum the carpet to clean up the corn starch. Most of the time, there will be no permanent stain on your carpet.
It is important to remember that you need to do this before the spill dries out on your carpet to obtain the best possible result. This trick also works with other types of spills.
