Ah laundry detergent, those famous adverts and the very smelly detergent dispenser! It can sometimes be a headache to find the detergent that's right for you (suitable for your clothes/sensitive skin, perfumed but not too much, with ingredients that aren't too allergenic or bad for the environment...). The problem is that the ingredients listed on detergents and cleaning products are very limited: you'll often find "contains ionic and anionic agents", but it's hard to find anything more vague than that! Especially as commercial detergents are often expensive, and organic or ecological detergents are no more transparent about their composition (even if some claim to contain 100% natural or plant-based detergents). In any case, buying commercial detergents means producing a lot of waste, especially if you use plastic bottles, tablets or cans. In this tutorial, I'll show you a quick, easy and economical way to make your own 100% biodegradable washing powder!
Advantages: Single-ingredient, can be made without heating, natural fertiliser, no odour and doesn't obstruct drains, free because you can use a "waste product" from wood fires. Unlimited conservation thanks to the basic pH.
Disadvantages: not suitable for delicate laundry, tends to make white laundry dull in the long term (can be made up with percarbonate), for the garden be careful because pH basic.
The large majority of detergents used are based on products containing sodium as the active agent, which once released into the environment is not only alkalinising (increases the pH) but also salinising in the long term. One of the great advantages of ash detergents is that the active ingredient is potash (the ionic form of potassium, the K in the famous N-P-K tryptic of agricultural fertilisation). Even if the discharge from your washing water continues to be alkalinising, it will fertilise your environment with an element that is often forgotten by gardeners and is harder to provide than nitrogen !
How does it work ? After stirring, the liquid is loaded with potassium salts. In the washing machine, when it comes into contact with the grease on the dirty clothes, this potash is transformed into soap. Basically, the more grease there is, the better it washes !
Once the ash has been collected, take the time to screen it over a bucket to eliminate anything that is not ash and could float ( charcoal, wood) or sink ( metal from the crates etc).
Be careful, the fine dust from the ash can irritate the eyes and lungs. You can wear a mask and goggles if you feel uncomfortable. For your own comfort, try to stand outside in a place sheltered from the wind.
Pour into a large bucket or bin with a lid (to prevent rain and other outside elements from falling in).
Stir well and leave to macerate for at least 48 hours, stirring occasionally if possible. You can forget about this maceration for several days/weeks/months, as it will continue to concentrate until it stabilises.
Cette étape n'est pas obligatoire, vous pouvez très bien utiliser le seau de macération et prendre le volume de lessive dont vous avez besoin à la surface, en veillant à bien avoir laissé décanter la cendre au fond.
Si vous souhaitez filtrer, prenez un linge propre, des gants, et un seau. Après avoir filtré dans un grand seau/casserole il est plus facile de transvaser la lessive dans une bouteille/bidon avec un entonnoir.
La couleur peut varier suivant le filtrage : transparente, ou jaune/brune. Il suffit de laisser décanter et bien éliminer les restes de charbon avant de mélanger à l’eau.
