How to clean uPVC windows?

uPVC windows are generally made to require virtually no maintenance at all. In case you want to clear the dust off once in a while then you could go for the special uPVC window cleaning solution that’s readily available in the market or you could stir up a solution with 1 cup of vinegar with 4 cups of hot water. Just spray it on the window & wipe the dirt off. Then just gently buff the window with a dry cloth but vinegar might reduce the life span of the window as it contains acetic acid so ready-made window clean solutions are suggestable.
