Hey, thanks again Rob, I wouldn't have thought of that. Usually those Draino/Liquid Plummer products say leave it in the drain for 30 min. or so before flushing. So would you suggest brushing it on and leaving for 30 min. before hosing off? Or would it need to soak maybe overnight? If better to soak, any risk that it would be too caustic and eat the metal? Many thanks.
