Cleaning & caring for stone / concrete driveway

[ElBarto619]

Hello,

I've started using my pressure washer to clean the outside of my house and use it on the driveway and walkway I have which is a mix of concrete and stone I think (have attached a photo) but I noticed some of the stones came loose using the pressure washer. Should I stop using it? Or it is it the case that those stone were likely already loose? Also does this kind of driveway need any maintenance or care that I should know about?

get a round patio washer for your pressure washer - it whizzes round under a cover so cleans more gently and thoroughly Karcher T350 or T400
