How do I remove polymeric Sandthat dried on our brick pavers??

Replaced an ugly, broken concrete slab with bricks (polymeric sand is in between bricks). This was a time consuming project. We bought sealer, but can’t figure out how to remove the sand that stuck to the bricks and don’t want to seal the patio until we get the bricks clean. We have tried: hard steel brushes, vinegar, a heat gun and, of course, a power washer. The power washer also power washed out much of the sand between the bricks. Any different ideas? Our Chicago unpredictable weather is upon us. Hoping to clean the bricks now and wait for Warner spring weather to seal. Did anyone else find a solution to this problem? I’ve searched online, hence the various methods we tried and rejected. We love the patio, but knowing this last part - sealing - isn’t done takes away the total enjoyment.

Charlie especially enjoys the new patio regardless of its imperfections. Going to enjoy many years of drinking coffee outside once it is completely sealed.

      I’m sure the photos are deceptive, but they are definitely different than when we laid them and it happened after we wet the sand in between the bricks.

    Is the sand a loose sand or hard like morter? If loose, as you roll on sealer, you'll put more sand on bricks. Is the brick exterior rated brick? If so it is already sealed. Sorry, I've never sealed exterior brick and we have bad winters.

      Hi, the company sold us sealer so they must think we need it. I am hoping that the sealer also keeps the cement- like sand in the joints. Thanks for your help.

    It's very frustrating when this happens. So I came here for suggestions. My paver stones aren't sealed, and I guess that may be the reason why this happens. The worker who did our backyard told us there's no need to fill it, as it's just useless money spent. He was the professional. I trusted him. It turns out the sealing is a must. I'm thinking now to seal it. I'll call somebody else to do the job. I can't scrub it every day, hoping it would look better. And I don't want to replace it with anything else.
