So tell me, just how do they clean then? Explanations on a postcard please.
Short answer is that they do not remove half the detrious that the normal wash process does, but it sounds good. It's like the detergent-less washer, yeah they work, if you pre-treat like crazy with (shock) chemicals.
As I said in that thread (more or less if not exactly) the best thing for people that suffer from a delicate skin is extra rinsing, more water and proper cleaning. The proper cleaning gets rid of stuff that will irritate the skin, the water level higher allows the detergent to work correctly and be in a decent ratio with respect to the fill and the rinsing removes the detergent. It's not rocket science.
Reduce the detergent, you lose the cleaning
Reduce the water, you concentrate the detergent which you still need to achieve the performance.
Reduce the rinsing and you leave detergent in the clothing.
Eco-balls et all work on the "rock" principal where, in the stonge age and still some Third World countries, you wet the laundry and slap it off rocks loosening the dirt until it is "clean". How clean is up for debate. However, this is carried out usually in a flowing body of water, like a river, where there is loads of water to carry off the dirt, if of course it's clean, if it's not then it's pretty much a waste of time.
This is the very principal on which Zanussi's Jetsystem is based where little water is used yet the clothing is still soaked and then effectively "slapped" off the drum to loosen dirt. Some swear by it, most people wouldn't know the difference.
Simple chemistry (Chemistry 101 if you like) dictates that to remove staining, grease and other nasty stuff requires three components...
Water, to provide a means to hold the dirt in solution.
Heat, to loosen the dirt and activate the detergent.
Detergent, to attack the dirt, loosen it and then hold it in the solution.
It's why you wash dirty dishes in hot water with detergent and I've yet to see anything defy that simple physical law. And whilst all these things claim to be better,more eco-friendly or whatever I tend to regard them as snake-oil until scientifically proven.
This subject really cracks me up at times as I've seen so many things that claim to be God's Gift nd on analysis they turn out to be total tosh. The topper for me is additives like Vanish etc., talk about snake oil! :roll:
