ᐅ New efflorescence appearing all over the new retaining wall!

SchnubbiUnfortunately, our newly built wall has become an eyesore... Our terrace wall was supposed to be a highlight, but now I just want to look away. The manufacturer only says that we have to live with it and that it will disappear over time due to weathering. We were not aware of these issues with concrete blocks and approached the wall rather naively. What options are there? Without damaging the wall, making it look even worse, or just watching and hoping that after 3 years it might finally look like the wall was meant to...
The wall is intentional and should not be covered... I am looking for experiences regarding whether it helps, for example, to wet the wall more frequently during the week to simulate rain, or to brush it with soapy water... The stone should not be damaged in the process. Perhaps someone has faced this exact issue. Thank you

The bricks looked like that even before installation, and as far as we know, it will disappear over time due to weathering... I am looking for a way to speed up the process. What’s strange, though, is that the pattern runs from the top brick all the way down. So it has spread from the top row of bricks downward. How could that be efflorescence affecting only the top row?
Best regards,

This happened while storing them outdoors. Since they were freshly produced, salt/lime deposits (I’m avoiding technical terms here, and don’t really know them) formed during the rain and ran down from the top... We are satisfied with the moisture resistance, but I guess we need to install a drip edge or similar.

Usually, such streaks are water-soluble. I would try to clean a 1m² (11ft²) area with a pressure washer to see if that removes it.
