60 Wash Persil Bio Washing Powder with Biodegradable Ingredients This washing powder can be used for both machine washing and handwashing. If washing clothes by hand, follow the instructions on the pack and dissolve the washing powder completely in water. Always test the colourfastness of any newly coloured clothes before laundering and wash light, dark and coloured clothing separately to avoid fading or colour run. For heavily soiled laundry items that need a deep hygienic clean (such as bed linen, towels and underwear) wash at higher temperatures of 60C or above to help remove germs - please refer to the garment's fabric care label first. This powder is brilliant at removing tough stains like grease, oil, mud, grass and chocolate ice cream. With an effective formula for stain removal and long-lasting fragrance, Persil biological washing powder is a great washing powder to have in your cupboard, especially if you have kids around.
