In reference and addition to this question, I was wondering if there is a good recommendation for water spray nozzle after foam cannoning... I have a gas powered pressure washer that has taken wood off a deck if not used properly and I would hate to damage my paint but am really looking forward to getting a foam cannon!! (obviously I wouldn't spray it at my paint in a way that could take wood off a deck but was just hoping for any suggestions for best pressure/safe cleaning) - thanks!
