Some carpets require gentle care, and I would not recommend removing anything from them this way. Not everyone knows that a unique approach to cleaning is necessary depending on the rug's composition, the type of dyes used in it, and the way it is made.
We had a very beautiful, expensive rug in the chief's office. One day one of the employees spilled coffee on it and tried to remove the stain. Good thing we stopped her in time. And we contacted commercial cleaners, and they were able to carefully remove the stain.
