I retry my chance after the first time, this time I scrupulously respect the prescribed doses, I still have problems with the concentrates. I must admit that the fragrance is very nice, and the product is stable, I mean, I mix the concentrated product with water in a spray to use it on the tables and plans work, and that the mixture remains. The same product thinned remains ready for use immediately. Not suitable on glass surfaces, such as a cooking surface, it leaves traces, for the rest good cleaning, resistant perfume, at least on soils with less diluted product!
