I had heard of these walnut shells that have a power washing, but I had never taken into account, I take a long-standing ecological detergent for washing machine .... But it will also be environmentally friendly (I am not so convinced) but there are still plastic containers and disposed of, I tried the soap grated and dissolved in boiling water, but even that I was not very satisfied, after grated cooked, I found myself at the end with solid soap .......
These nuts are a plant that grows in India " Sapindus Mukorossi ", are an 'alternative to normal washing detergents, are 100% biodegradable, are inexpensive, come from renewable sources ..... I tried them and I must say I am very satisfied, Heads are very clean and soft ..... with a bag of 250 gr. which costs 4 € you do about 50 washes, I am very satisfied and they do not pollute because when they go throw them in the compost .....
