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

If you're treating a stain on a piece of fabric or clothing, stretch the fabric over a large bowl. Position the stain in the center and wrap a rubber band around the outside of the bowl to hold the fabric in place. Bring a kettle of water to a boil and slowly pour the hot water through the stain and into the bowl.  The hot water can loosen the stain and force it out of the fabric. If you're cleaning a fabric stain on a couch, you'll need to remove the cover or cushion to get to the stain. Get out a small bowl and pour in 1/4 cup (60 ml) of gentle dishwashing liquid. Stir in 1/4 cup (60 ml) of hydrogen peroxide until it's combined. Apply the solution to the stain and let it just soak in for 20 minutes. Once the stain looks like it's lifting, wash the material in the washing machine. Only use the brightening dish soap solution on light fabrics since it can lighten dark fabrics. Another way to lift stubborn stains is to coat the stain with white vinegar. Take a few spoonfuls of liquid laundry detergent and rub the soap in. This should loosen the stain. Wash the fabric in hot water to completely remove the stain. If you don't have very many materials to make a deep cleaning solution, just spray club soda mixed with equal parts of white vinegar over the stain. Use paper towels or an old towel to blot up the mixture. You can repeat spraying and blotting until you see the stain lifting.

Summary:
Pour boiling water through the material. Apply a brightening dish soap solution. Apply vinegar and liquid laundry detergent. Spray and blot up a club soda and white vinegar mixture.
