First Briquez bubbled for longer

I tried this first in the cunette circular enamelled shower tray, the latter tending to fade, because of dirty soapy water discharged daily. After bricked abrasive soap to scour well, I have fully sprayed and wiped with a cloth attached. The gloss is back with a slight satin sheen. I proceeded in the same way in two sinks and faucets, shiny guaranteed after wiping with cleaning cloth.
When the second magical effect (major effect in reality), that relating to the prevention of dirt by the character "water repellent" of the product, it seems obvious on sloping surfaces with rapid removal of the liquid, less obvious on the receiver shower where the slope is obviously much lower. This shower receiver does not seem to me either be transformed into ice which would not suit me more. So before you say "I love" (4 stars) I prefer to use the dimension (-1 star) = I expect to see.
I am convinced, in fact, when the laughs will remain bright satin for at least two weeks without having to wipe the slate clean with an abrasive soap.
If this is the case, I would add a star, if I will live longer with 5 stars to announce the triumph of chemistry on the slow trickle of dirty water, and finally one of brick First that it shines durably and we can laze long.

One week later:

I must admit that sinks and shower tray remained clean and shiny with hardly look after a shower hit here, a rough rinsing by hand without rubbing there and everything remained nickel. It is true that here the water is very calcareous but the effect of this is significant and deserves one star, 5th next week?

15 days later:

the repellent effect begins to run out, though he will not break for at least 10 days, just give a sponge and spray again, it's over. The test is actually successful, I think it is an excellent investment, great home, also for professionals such as hotels for example.
