Working on a quote for a large home that has cedar shakes. In several areas there is considable mold that the owner would like removed without restoring or cleaning all the shakes. Also a lot of the gutters, soffits, and facia is green and needs to be cleaned. Will that be possible without staning the cedar shakes of it splashes on them. My normal mix is SH/Water 50/50. and eleminator at the recommended ratio. Any comment would be welcomed.

Thanks in Advance!
