How do you brighten white ornamental stones to look white again?

The stones around my lawn are dull and I want to make them look brighter and whiter.

    Are these stones large enough to be pressure washed? Are they small enough to be put in a bucket with some Dawn and peroxid? Can you scrub them with a toothbrush and soap? If all else fail, a can or two of pearly white paint might be pretty. TeresaC

    Thanks for the ideas. They are small enough to put in a bucket to wash but we do have hundreds of rocks. Maybe I can sprizt them with Dawn and peroxide and let them air dry. What do you think about spraying bleach over them?
