In an Italian forum with many Nuavia fans and with more than three hundred messages on the subject of Nuavia soap, the method for obtaining a good foam is written.
There it is written that the right amount of water and soap for Nuàvia is respectively four and seven grams, precisely four of Nuavia and seven of water and there is nothing written about the two phases therefore in one fell swoop. the method used by fans of the 4H47 party!
I have never used Nuavia, although it seems you wrote that the instructions on the soap are written a little differently, i.e. three grams of soap and seven grams of water.
There are those who have tried using this method with other soaps and write that they like them, but four grams of soap is a lot of marketing strategies to consume more soap and finish the bowl quickly.
It did not work. It makes no sense to take the scale and the syringe to the bathroom to measure the grams of soap and water.
nonsense
