The area between my house and garage is mostly all 3/8" crushed blue stone except for a ~3' perimeter out from the house and garage where there were flower beds. I want to run the stone right up to the house and garage, nix the beds (long gone). I will dig out the dirt 3-4" and fill that in with stone. The existing stone has been there quite a few years. Filled with decayed leaves/flakes, dirt, etc. Any good way to restore the existing stone? I'm going to put a thin layer over the existing to build it up in some areas, but, I'd like to get it cleaned out. I wish I had a screen contraption to wash the dirt/sand out of the piles of crushed stone I have sitting off to the side!
