Cleaning a block paving driveway?

callmechar

Our driveway been down 2 years. Now got a lot of weeds in it and is dirty. Wants to clean it, prob with a pressure washer (which I want to buy). However, have read different things online and not sure if I should use a pressure washer.

We intended to replace the kiln sand between the bricks but not to compact it again. I know the sand will get washed away. Is this ok? Some things online said it will need compacting again.

Should we get a pressure washer with a patio attachment for cleaning the drive? Is this better or a lance?

Thanks

Done my driveway once a year for 7 years and no issues with a pressure washer. Not every year but a couple of times i have replaced some of the sand with a yard brush. I tried a patio attachment they dont clean good enough. I have a Nilfsk pressure washer

No problem, but one of those patio joint scrub brushes with the V metal bristles first to clean the weeds out . just spread the sand and brush it into the joints after jetting.
