Q&A for How to Remove Red Wine from Carpet

It is extremely unlikely that a wine spill will still be damp after 4 weeks. It also seems unlikely that your guest spilled a bottle under your bed. You may want to hire a professional to take a look at what's going on underneath the carpet. You could have a leak of some kind or mold growing in the carpet. A normal wine spill should be totally dry after 4 weeks.

It's worth a shot, but it can be extremely difficult to get dried wine stains out. You may need to use a bunch of different solutions to get the stain out slowly over multiple attempts. At the end of the day though, you may just need to live with a little discoloration. Some wine stains can't be totally removed.

The thick loops in berber carpets can hide dirt and stains from the surface. Over time, as you walk over the carpet or drag objects across the surface, the fibers can bend slightly to make it look like the stains are reappearing. You may just need to clean it multiple times.

Salt will just make a bigger mess. If the stain is gone, let it sit for a bit and then repeat - using less dish soap and a little more water. If you use too much dish soap, it will "track" later back to the stained area and you will notice more stains in that location.

Try Vanish carpet stain removing foam. Apply several sprays of this and leave it on the carpet for a bit, then vacuum. You may need to repeat the process two or three times for dark stains.

Some linens require a solvent-based cleaner, others are fine with a water-based one. Always check the manufacturer's instructions before using anything on linen, as it might cause shrinkage if you use the wrong product. For solvent-based I recommend Spot Shot (royal blue can with an orange cap), and Wine Away red wine stain remover.
