Hi all...having recently moved into a new terraced house with a small backyard which is currently laid with large white stones. They aren't in the best of shape and they're pretty dingy-looking, but our problem is that we don't have any access to the rear garden except through the house itself, so it would be extremely difficult (not to mention expensive) to replace all the stones outright. Can anyone think of a way to neaten up the look of the ground out there? My hubby has suggested soaking all the rocks in a bleach solution, but I'm not sure that would work, as well as being quite time-consuming. I don't imagine pressure-blasting would help either. Any ideas?
