100% Indian Nuts Natural Cleaner Laundry Detergent (Soap Nut) . The organic Indian soap nuts can be used to wash many times; at a 30°C temp – 4 times, 40°C- 3 times, 60°C – 1 or 2 times and once at 90°C. Unlike chemical detergents, Indian washing nuts do not dissolve the dyes in the fabric so you can mix different fabric colors without fear. As long as the nuts continue to produce foam, they still contain saponin. The gentle cleaning features of these nuts help in maintaining the color of clothes longer. You can use the soap nuts for hand wash and machine wash effectively and they can be used for both white and colored fabrics (between 30° and 90°).
