I'm trying to clean my inside windows. I've tried Mr Muscle, Betterware,
white wine vinegar, washing up liguid in hot water, and they're STILL
smeared. Please has anyone got a sure-fired way of getting smear-free
windows?
Thanks



Go and get some AUTO GLYM car windscreen cleaner. Put it on and then rub
the haze off to leave a clear finish. It takes smoke and grease deposits
off. Or you can buy a solvent based cleaner that window fitters have.
Make sure it's not a fault with your double glazing. My neighbours had
some cowboys in who supplied sealed units that look smeared from the
outside. The vacuum must have been too great as the glass is somehow
distorted compared to everyone elses.



BTW No vacuum is employed usually in double glazing, panes are sandwiched
and just kept apart at foiled edges causing a slender airpillow (not an
airgap) and often accompanied by silica-gel granules to counteract moisture.
Bottom shims and fillers are essential when hanging/positioning the DG
module in its taller/wider framework.

Maybe somebody before you used too strong a caustic chemical
that affected its finish with a "permanent" smear.

I'll go with Windolene, which is basically white spirit and chalk I
think. The solvent shifts virtually anything and the chalk absorbs the
residue but, unless what's on the glass isn't water soluble, water would
do just as well.
