To be honest it all depends what exterior property cleaning job I'm on at the time which chems I may chose to use.
For instance on say a full render clean/house wash down would normally check & clear gutters first, clean fsg's , stone/plastiic sills, window frames, door frames, glass etc . For instant results I've found a hypo soap mix works rather well on plastic, cladding, painted wood, render, brickwork. Not to mention ground surfaces like driveways, patios, paving. decking, etc.
Anyway it looks like we are all doomed now what with the new sniper nozzle and all. lol
