Removing salt from paving bricks - How do I get it off?

hello dear forum,

I have a huge problem. I spread salt on my ABC paving bricks in winter and now I have residues everywhere. The clinker turns really white when it is dry. I have already tried to get it off with a high-pressure cleaner, with Mellerud nitrate remover, and a scrub brush. Even when I turn them over, it still draws back to the surface.

Is there any way to get it off?

Please help me.... I would rather not replace all the bricks.

Best regards

Are you sure it is salt? Some (dark) artificial stones effloresce after a certain time. However, this usually subsides after months/years.

Yes...I am...it's only where salt was also spread

Clinker bricks can bloom, it is no different with clinker paving. With bricklaying clinker as a wall it is even "normal," because the salt bound in the mortar is transported outward through moisture. It washes off over time. With me (wall clinker), after almost half a year, it suddenly bloomed heavily on the shutters, it was really white. After a few days/weeks, it disappeared again due to the rain. You have now spread salt (isn't that even forbidden in Germany? If so: Karma^^), instead of the salt coming from the mortar. As Nils said, it should decrease over time. You can also try to reduce it by brushing and rinsing. With a high-pressure cleaner, I could imagine that the salt is just pushed further into the stone. Chemistry probably doesn't help or only makes it worse due to its salt content. I suspect you will only get rid of the salt if the salt can dissolve in water and run off. If the water only evaporates, the salt remains again. In other words, the only things I can think of are gentle watering and rain.
