> Then you must do a slapdash job squeaky.
i can not see how a dirty green conservatory , complete with gutters , and windows can be done in 1 hr , esp. when there are dirty run marks on finials , cross bars , and gutters, that will not come of with wfp , even hot , without using a chemical of some sort.
if you can do them in 1 hr , it is not that dirty to begin with, or your defination of clean , is not the same as mine.
