I have just seen that you have a whole range of new dishwashing detergent creations in the store (Migros Neumarkt Oerlikon), but they don't convince me at all because they contain all kinds of additives that only have a negative effect on me. I hope you keep your classics like Manella and Handy.
What I do find questionable is their combination of cleaner/dishwashing liquid that has an extra warning for eye irritation on it. I actually liked the idea because the Potz Orange leaves the surface more sticky than clean, but if they have an eye irritation warning on the bottle, I wouldn't want to wash my dishes with it. Maybe you can find something more convincing.
Kind regards
