In one sentence, describe what the following article is about:

Open a bottle of white wine. Pour it liberally over the stain. Do so in order to neutralize the red wine’s pigments and possibly lift the stain out entirely. Of course, you may not have white wine on hand, or you may not be too keen to waste any more on top of what you spilled. In that case, pour distilled white vinegar over the stain instead. This will also weaken the red and purple pigments and, like the white wine, could possibly remove the stain on its own. This may be easier to do with a partner, so ask someone for help if you can. First, boil some water. Once it’s ready, hold your jeans over the sink and pull the stained area taut between your two hands. Then have your partner pour the water onto the stain from a height of roughly 12 inches (30 cm) to wash the stain out. Wear rubber gloves while doing this so you don’t scald your hands. With sparkling water, don’t worry about boiling it as you would with plain water. Also, don’t worry if it’s gone flat and lost its carbonation. Simply pour it over your jeans to lift some or all of the stain out. Pouring the liquids above works best on fresher stains, so if yours has already dried into your denim (or if you spilled a lot of wine over most of your jeans), don’t worry if that didn’t get the job all the way done. Fill a container with enough vinegar, white wine, or club soda to soak the stained area, and let your jeans sit in it until the stain fades. Don’t use boiled water to soak your jeans. Warm water can actually make the stain settle in faster if your jeans are just sitting in it.
Neutralize the red wine with white wine. Do the same with white vinegar. Pour boiling water over the stain. Pour club soda over the stain. Soak large or dried stains.
