Cleaning Dead live rock (color wise)

[Grimreefer89]

Is there any way to lighten up the color on these rocks. I know they shoukd all purple up but until that happens its gonna drive me insane. Ive bleached and pressured washed them any suggestions. I know you guys have some tricks up your sleeve.

Bleach and sunshine. You can’t take away the natural shades of white/tan/grey...they look pretty clean to me from this pic.
