test drove today on first house a bit awkward, lots of fumbling around did upstairs and down on one house then whent back hour later to check, few tiny white run marks so polished off with micro fibre looked a treat. As i only plan on using on dodgy windows to start i don't think i will get complaints and further cleans will improve so everyone wins. The house i tried on taday is a bit of a knee wobbler so better for me as i am a bit more nervouse following my fall, anyway sleet stopped play so will try again tomorrow
cheers simb0
