That's perfect.
For the product, I use it on the advice of an appliance repairman for over a year on my dishwasher and my washing machine.
It's supposed to be replaced softener product of great brand which we see advertising on TV which is used in each wash.
With this product, once a month, and, honestly, for the moment I have not found change but it is more economical.
