My mom got this surf excel easy wash washing powder last year and realised it whitens off yellow turned clothes and brightens colors in a whooping single wash. It gives the old fainted clothes new life and softens clothes after washing. The clothes which your old detergent turned hard and liveless after drying will also look good and will become soft.
A small amount ( about 2 gms) of powder is enough for 1 bucketful of clothes ( 10 to 15 clothes) and not even a handful or palmful of powder is required so a pack lasts really longer even a 4kgs go for 2 months. Price is little more as compared to other detergents but little powder is enough so one pack lasts longer and atlast if your clothes are handled with care and their quality is preserved for long what else anyone will want. This powder does all of these. Do try it once for better results.
