It looked very good after the clean. After few weeks, they saw some black marks appeared where they cleaned! What could have caused the black mark to be visible like that?
The reason for that is: the portable machine they used was not powerful enough to remove the cleaning product from the carpet. The detergent that was used attracted the dirt and voila!
It is really important to use the right cleaning product and the right equipment if you want to avoid marks like this one!
