This product is suitable for all washings, effectively complexing calcium, magnesium and iron ions in water to prevent graying and yellowing of cloth.
Prevents the fabric from yellowing due to iron content in the water (as low as 0.2ppm). If the water hardness is particularly high, the product can be added during pre-washing to dissolve the soap scale on the fabric.
Soaping on the dissolved fabric: 2-3 ml per 1 kg of fabric helps to remove the soap scale on the fabric, thus reducing the fabric ash.
Hard water treatment: 0.5-1 ml per 1 kg of fabric is washed and/or 3 times over water to improve the washing effect and prevent fabric ash from being caused by calcium and magnesium deposition.
