New terrace wall efflorescence everywhere!

Plant a hedge in front of it, you don't want to see such a massive wall all the time, it's never nice.

The stones already looked like that before installation and to our knowledge it disappears due to weathering... And I am looking for a way to accelerate it

The wall is intentional and cannot/should not be covered... I am here looking for experiences, for example, whether it helps to water the wall more often during the week/to simulate rain or brush with soaps... the stone should not be damaged in the process. Maybe there is someone who has had exactly such a problem. Thank you

But what is strange is that the pattern runs from the topmost stone all the way down. So it has run down from the top row of stones. How can these be efflorescences that only affect the top row?

It happened during outdoor storage, since they were freshly produced, salt/lime deposits (I’m avoiding technical terms, I have no idea either) formed during the rain and ran down from the top.... We are satisfied with the moisture, probably need to install a waterfall fe

It looks as if the stones were filled with concrete; if this was applied too wet, the water appears as concrete streaks at the joints. As a rule, such streaks are water-soluble. I would try on 1m² to remove it with a Kärcher.
