How much does it cost to get a carpet washed?

There are companies, such as carpet shops that do not have the possibility to weigh the carpets and companies that wash the carpets in the machines, which calculate the cost of cleaning by the square metre. In the Craftsmen’s lists, instead, the cost of washing is calculated by the Kg, we stick to these and thus we calculate washing by weight. For antique rugs that are very light an estimate is made at the time of the withdrawal so that the customer can accept it or not.
