Hi Bob,
Thanks! There actually wasn’t too much difference in colour and not much green or brown came out in the cleaning phase. I guess the previous owners were kind to it. But boy, does the water bead up nicely now! Far better than before. The water looks like little jewels against the black roof. I did take a before shot, and wills end it to you later today in case you can use it.
Best wishes,
Carolyn
