There are many benefits. The most important thing is that if you or your family suffer from washing powder-related symptoms, such as skin problems and/or breathing difficulties, you owe it to your health to switch to a non-chemical alternative.
From a financial point of view, you should be able to save hundreds of euros a year on washing powder. You could save even more if you skip the rinse cycle, as it is no longer necessary (which would also save 20 to 40 litres of water per wash, which is good for the environment).
You’ll save time, reduce the effort involved in doing your laundry and avoid having to lug black bottles or packs of washing powder home from the shop every time. Your wardrobe (which is a considerable investment) can last much longer thanks to the reduction in harsh chemicals. It makes your home “greener” and also more child-friendly by reducing the amount of toxins in your home.
It can have a huge impact on the environment by reducing the use of chemicals and our reliance on imported petrochemicals (Yes, detergents are petrochemicals derived from crude oil).
Etc., etc.
