Pressure Washing a House.

Hi guys, I have been asked to quote to pressure wash a house from top to toe and patio and conservatory, but am unsure which chemicals to use to remove moss and stuff from house walls. All help greatly appreciated. Cheers. Kev.

look up soft washing chemicals that might help.... soft washing gets bio stuff off walls etc.

i use chloras or hypo as its known in the uk , its available in swimming pool suppliers or farming co ops thats for removing the moss and algae from the walls or the patio or concrete paths etc . for any upvc including connys i use ubix 2000 from clover chemicals , for the roof you can manually scrape it off or low pressure wash it off . we could give you some idea of price if you got a pic
