How to remove clay dust from concrete paving

Moinsens,

with us, after almost three years, there is still an increasingly deteriorating construction road. Last year, we laid 90% concrete paving on our driveway ([Baustraße] should actually no longer exist for 2 years). Because the [Baustraße] is getting worse and worse and clay is now coming to light, we have now driven a nice track of clay onto the driveway. According to the manufacturer, it is virtually impossible to get the clay out of the stones.

Do you maybe have an idea?

Best regards

I would try using a high-pressure cleaner and a surface cleaner first. If that doesn't help, try the spray lance, and if that still doesn't work, use the dirt grinder.

I once had clayey excavated soil lying on interlocking pavement for a long time. Sometimes even driven over with the car. Once the excavated soil was gone, I went over it with the surface cleaner, and where it was almost gone. The final touch was done with the spray lance.

Concrete paving and high-pressure cleaners do not go together.

That is why I also mentioned the surface cleaner since it does not have that much power. In addition, the pressure that the high-pressure cleaner exerts on the surface to be cleaned also depends on the distance of the nozzle to the object.
