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

Don’t reach for a cloth towel because the red wine will stain the towel. A degreasing dish soap works best. The salt should soak up the wine, preventing permanent staining.  Leave for 30 minutes before rinsing with clean water.
Use a paper towel to blot any excess liquid from a fresh spill. Use a paper towel soaked in dish soap and warm water to scrub the stain. Pour table salt onto the stain and allow it to sit for 30 minutes. Pick up salt with a paper towel and rinse the area with clean water. If color remains after the salt application, place hydrogen peroxide in a small spray bottle and spray on the affected area.
