Hi everyone,
got a major problem...I clean 2 new build houses to day which had lead windows, the first house the owner asked me to used water only! The second a mixure of fairy and glass gleam...on the second house it was going fine until the last two windows I was applying water and squeging off the excess and buffing up the window with a microfibre. Seconds later there was a white smear all over the windows I as hard as I tried it would not go! Can anyone tell me why this is?? I feel awful about this as they are a good customer!! Many thanks, Henry
