Carpets, as materials of style and elegance, are known to provide actual thermal resistance, or R-value. Proper rinsing of the carpet is accomplished by using a rinse that neutralizes the cleaning solutions used to clean the carpet. Well-designed wands are in near-to-complete contact with the carpet, enabling better extraction. If there is any such requirement of stitching the carpet due to flood damage, then they will also provide stitching to your carpet. But NEVER pour the alcohol directly on the carpet as this can dissolve the backing and cause the ink to migrate toward the backing.
