I bought a Broadex hose reel when I set my system up and after using it for the second time I noticed orange spots on the window? Being a novice I presumed I was doing it wrong,I asked friends that use the pole if its possible that the reel could rust but got a funny look ? Well I've stripped it down and the steel elbow that's connects the pipe is full of black grim and rust ? Is this an isolated problem ? Just didn't expect problems like this with all new gear !!
