ive been fighting the smeary deposits on the windscreen on my Picasso for a while
even the pole's wash n wax locally does not last without all the wipe marks appearing next day
so windolene ,autoglym ,halfords, turtle wax, thinners and water , brake cleaner, newspaper,neat screen wash,
all have been rubbish
but white vinegar wins hands down ...its worked a treat
so what do you use ????????????????????????????????????
