This Waschei was one of the most rewarding investments at all. For several years we only use Ökowaschmittel. This protects the environment on the one hand, but on the other hand brought a slightly musty smell after washing with it, which was otherwise covered by the perfumes in the conventional detergents and often came out again only when sweating. Vinegar rinse, 60 degrees, airing and washing out of the machine, no storage times of the washed items in the machine - all this has not been a resounding success. But since we with Ecoeeg and about 30 grams Ökowaschmittel (without I have not yet dared) wash, this smell has gradually disappeared after entirely. The laundry is softer. And it is clean. Stronger stains I have anyway always pretreated with enzyme prewash short, because the well only creates the chemistry club, but not Ökowaschmittel. And the great thing is Ecoegg which are supplied by the mineral balls several refills. You can open the egg and so the balls vent every now and then also times and let it dry properly. So from me a total purchase recommendation! Important to know more: the manual is completely in English.
