It is recommended a lot of 2-5 grams per liter of water (depending on the degree of calcification).
At first I found using a watering the approximate amount of water of the washing machine, which were with us around 15 liters up to the lower edge of the drum opening.
I have 75 grams of added (preferably in a dosing ball for liquid detergent) starts and the 95 ° C wash program.
Apparently quite a wash cycle has sufficient because since are no residues in the fluff filter.
For other Entkalkungaufgaben the powder is very effective.
I gave and decalcified 1 teaspoon powder in our 1.7 liter stainless steel kettle.
After that he was a mirror finish.
During descaling, there is no pungent fumes but be careful when handling!
Even the smallest amounts of particulate matter (eg when transferred) irritate the mouth and nasal mucosa immediately.
And necessarily keep away from children, as the screw without Parental Control is!
Conclusion:
Very powerful and productive descaler.
I highly recommend him.
