I was looking for a (washing) means that the smell of the laundry improves. I've tried many, cleaned the machine, tried different detergent and nothing has helped. The laundry always smelled musty. After a short search I then hear about this product. The smell has definitely improved. Only 2-3 very thick garments sometimes gets even by the old smell. Otherwise, the laundry smells pleasantly fresh. Nevertheless, I do not give 5 stars because this agent is very expensive and yet, if you stick to the dosage, you have the bottle washed Ratz Fatz empty. But but I expect then that really smell all garments fresh again. I'm going to similar products that are less price-intensive to try and surprise myself sometimes. I can recommend it anyway.
