Stain removal (mostly for handmade carpets)
- To remove a fresh and shallow outward stain, we first try normal natural detergent and water. If the stain became steady and solid, first we verify the source of it then we use an ingredient of few Chemicals and materials (Sodium Hydro Sulfate and Natural Bio Yogurt are used in most of cases) in the form of a mild acid and apply the stained area for a very short time and let it dry. This can continue for several till few dozens of times till the stain is completely removed.
- For oil-based stains we use Petrochemical substances.
