Have also come across the odd enthusiastic homerowner with their new toys i.e karcher type pressure washers, garden sprinkler systems, home diy projects, bbq oil/grease spots/marks, diy attempts of FSG cleaning ...... all of these I do now charge for and have on one occassion charged 20 euros to clean one pane of glass because the kid had been out over the weekend and puked and that was on the glass....what else do you charge for ?
