Use a similar wand on the hose ,fortunately our water pressure is fairly high so no need to get a p/washer out. Also there are a number of fords around here with nice fresh water flowing so after salt spreading has finished a trip or two through one will get the worst off until a more thorough job can be done. This one we use regularly is good because it is Irish bridge style and has no gravel or slimey stones to worry about.
