ᐅ Removing sand from paving stones

Hello everyone, I have a question that seems easy to answer but actually isn’t that simple. Last year we paved everything and then brushed yellow sand into the joints for compaction. We had the sand left over from the house construction. Now the stones look like they were freshly blasted from a quarry. I have cleaned them once with a pressure washer and swept them ten times. No change. Even using the full jet on the pressure washer doesn’t completely clean the stones. Scrubbing doesn’t make much of a difference either. Even a surface cleaner attachment on the pressure washer doesn’t help. The stones no longer look like the original ones; they are much lighter and just dirty.

What do you recommend to remove the sand but without damaging the stone too much?
I keep thinking about a cement film remover, but isn’t that quite aggressive?

To meet your requirements for "cleanliness," or better said, "consistency," you will need a specialized cleaning company that will seal the paving afterward. This should then be done every 3–4 years.
I find the condition completely acceptable in terms of what can be expected.

The following sentence is not meant to be offensive:
But have you looked at my pictures?? There is a difference like night and day.
We paved 200 sqm (2,150 sq ft), which was quite expensive, and now the stones really look like they were just blasted out of the quarry.
That’s really frustrating for me, especially in the early phase after the new build.
And yes, it might sound a bit petty when I say that this stone was used all over our neighborhood and it looks there exactly as it should.

If the stone looks like that after 5 years, well, so be it. But ours never looked new or even reasonably clean (except when it was delivered and still on the pallets).
I could have just bought cheaper stones somewhere else and laid them here myself.

See, I’m not fat either — just a bit puffed up...

.. do you have the same supplier as your neighbors? Apart from appearance, do the bricks differ in quality? Are they rougher? Do the cut edges look different?
