Cleaning scale from brick patio?

Hi,

Our patio has developed scale over the years. I am able to get the surface areas clean with good old soap/water scrubbing. However, I cannot remove the scale between the bricks.
Purchased a Drill Brush for some added scrubbing power & neither vinegar or CLR have made a dent. Someone suggested a power washer but I'm not ready to go that route yet.



I assume this is calcium buildup?
Any suggestions appreciated.

Thanks
