Clean and shiny, what more could you want?!
In its August issue (08/2016), the German consumer magazine Stiftung Warentest tested dishwasher detergents in various versions - containing phosphates and phosphate-free - powder as well as tablets.
The classic phosphate-free dishwasher tablet recipes from Thurn also achieved good results with the grades 1.9 and 2.1. Congratulations!
