Hello,
Last year, we had our driveway paved with red brick pavers.
The joints were filled with stone dust.
Unfortunately, since then, there has been a grayish haze on the stones and small hard residues on the bricks.
The contractor told us that it would wash off with rain. However, a year has passed, and there is hardly any improvement.
How can we clean the stones now?
What works best?
Best regards
Michael
