That's due to the soda and calcium build up residue of it, many manufacturers tries to replace STPP with Soda but obvioulsy with crappy results for ones having medium to hard water, I've tried these new ones and totally sucks IMO! They now have them made in Germany from a different manufacturer, the old ones were made in Luxemburg. I've not experienced the chalky residue strangely, I do have very hard water here, they just didn't wash at all! The dishes were so dirty....I still had dishes full of dried mustard and sauces from last day BBQ and always do the heavy soil cycle 65°c for everything.
A total S**t!
I will no buy them anymore. But I found very good the ones sold at Eurospin (an italian discount chain), both tabs and powders do have STPP and are way cheaper than Lidl's ones, actually LIDL increased so much the prices over here and you do not save anymore a dime by going there, so I think I'll no longer shop there so often, as I was saying I though discovered this italian discount which have really low prices and even more quality than Lidl for certain types of merchandise ( such Cheeses,sliced meats, pasta and pretty much all the italian classics) also have a greater selection of each product category than LIDL, plus an internal butcher that cut and cure fresh meats, makes rolls, meatlofs, burger patties daily and pack them, a thing I never saw in a discount like that.
Also laundry detergents from LIDL looks changed, , both Formil and Maxi trat they're selling now looks they're overloaded with soda and fillers,also they does not have the scent they used to, are almost scentless. They didn't wash well like I remember they used to in the past, they are different and more expensive.
First I've noticed this difference in the XXL Saturdays boxes promotions they used to do, but I thought it was because of this XXL promotion trick and that they did put a lower quality product to upset the XXL 100 scoops size promotion for the same cost of the regular one, but the new regular powder box I bought recently was identical to the XXL one, so they changed them.
Also the Formil express handwash powder that I was used to buy more often did disappear from the shelves for some reasons. Also, Formil liquid now comes in the new concentrated form, once it was 2,99, now is 3,99 and is not paragonable to the previous regular liquid, I finished my bottle so quickly as it is not really concentrated and does not wash good, just Maxi trat comes in the regular bottle where formil once used to come.
Lidl lost so much points lately IMO, glad I found the Eurospin!
