Hi, does anybody know the best way to clean a brick driveway with a power washer without pushing out the sand grout? And what is the best way to seal a brick drive way? Thanks

How long has the brick driveway been there? What are you trying to seal it with?

For about 3 yrs, not sure what to seal it with though Thanks

I've never heard of sealing a brick paver driveway... it's not the sort of thing that needs to be sealed. Try washing a small section with the pressure washer and see how the grout holds up. If it remains intact after washing and you're satisfied with the washing, do the rest. The only other way would be some form of solution [bleach/water or something] and lots of scrubbing. Remember not to have the washer nozzle too close to the surface.

Try using a whirl-a-way rather than a wand. It's less directed pressure at the grout. Using hot water will allow you move quicker.
