Hi I've recently started using the wfp after 10 years of traditional cleaning. Little frustrated at the moment as some windows seem to dry lovely and others sometimes can leave spots. My technique is to wash the frames, rinse them off, then clean the glass. Is it best to leave the frames to dry a bit before I clean the glass as I just clean the class as soon as I've cleaned the frames. Is it my technique? could it have something to do with the fact that ive used soap on the window before? Sorry for all questions.
