No more stains on the sofa, baking soda and glycerin remove them.

2 tablespoons of baking soda
4 tablespoons of dishwashing detergent
5 tablespoons of 9-proof cooking vinegar
2 tablespoons of glycerin
Mix the baking soda and dishwashing detergent in a container with water. Add the glycerin and cooking vinegar and stir until a foam forms. Apply the foam to the surface of the furniture using a sponge or cloth and carefully rub the dirtiest areas.
However, if you do not know what to do with it, you will have to take care of it.
