I have spent the whole of today cleaning leaded windows. My practice is to applicate the windows, squeegee, wipe off the water with one fine weave micro fibre and then buff up with another fine weave. I have noticed that some of the fine weave micro fibres that I have recently purchased from paragon and unger dont glide easily across the glass.....they seem to stick and have friction.Some of the older micros that I have glide so easily across the windows which makes cleaning leaded windows so much easier. I wash them all the same way, in the washing machine with washing powder.....I know fabric conditioner is a no no. Does anyone know of a fine weave micro that slides and glides across the glass with ease.
