Hello everyone,
In the summer of 2022, we paved the courtyard and paths of our new build with concrete pavers. During the winter, we salted the area 3-4 times due to severe icy conditions, and since the beginning of this year, these unsightly stains have appeared (see attached photos). Despite several attempts, I haven’t been able to remove them. I tried using a high-pressure washer and also applied a soda solution twice (100ml per 10 liters of water). While there was some slight improvement, I can’t get the stains completely or at least significantly removed. It really bothers me. Do you have any suggestions, or does anyone else know this problem?
I would appreciate your feedback very much. Thanks in advance.

Standard concrete pavers shouldn’t normally be that susceptible. Salt is still not good for them, of course.
Have you already tried scrubbing with a brush? Yes, but so far only by hand with a scrubbing brush and a simple brush, though I gave up quickly when I realized it wasn’t working. I might try now with a brass wire wheel attachment on a drill...
