Did a PVC clean today on two semi-detached houses. Sprayed hypo on the SFG gable and front and went back and cleaned them with wfp. Last bit to do I decided to try an alternative way. Sprayed hypo on SFG and then went up ladder and cleared out the gutter into a bucket on my ladder limb then cleaned the SFG with an old towel. End up getting a better result, saved on pure and it was the quickest I have ever done it.
