New terrace wall efflorescence everywhere!

Ours are from Weserwaben the Trendline long (for us also rather in the higher price range) ... are about 25 m approx. 500 stones. Painting would be the last solution for us.... Everything is nicely in the field of vision and we can enjoy it every day

Conversely, only concrete stones that were fired and have some paint splashes in them....

I looked at them

You could have taken some from OBI as well, they probably would have been cheaper,

Do you have a construction supervisor?

I'm more interested in solutions or experiences, maybe there's someone with exactly the same stone... Can I treat the stones with water using a street broom or brush, or does it spread even more? Of course, we could have chosen others... we picked according to our taste and hoped for a nice terrace wall... without a construction supervisor

I already asked, are they filled with concrete? If yes, it takes years for the lime to effloresce. I have even tried the cleaner from the manufacturer, even hydrochloric acid, it does not help.

Are filled with [Trasszement] and each individual stone is additionally glued with construction silicone. Acid is out of the question for us regarding the surface.

There is no point in using acid since it blooms from the inside. Get used to it or remove it.
