We asked Jolie Kerr if seltzer treatment for wine stains is truth or myth:
"It works for sure! … It can work for basically any stain and the reason that it works is because you’re getting to it immediately with some water. It’s not so much that seltzer is so totally magic. The difference that seltzer has that flat water doesn’t have is that it has some sodium in it. Sodium is a pretty good stain-killer. … Salt is the go-to when you have a red wine stain. When you have a red wine stain, pouring a whole bunch of table salt on it will suck it right up. It has to be a fresh stain. … Just plain table salt [no water]. … You can go pour some wine on your carpet tonight and try it out!"
