Dry is good, wet can be bad
A crucial factor in cleaning a rug is the question of whether it gets properly dried after the washing. You can do a wonderful job of cleaning the built up dirt, but if you don’t properly dry the rug, you may be creating a new problem.
After washing, every effort must be made to remove the excess water left in the rug. Once this has been done, hang the rug in a dry, warm room with constant air circulation. At the Hadeed plant in Springfield Virginia, there is a state of the art drying room with a full system to keep dry air flowing on the rugs.
