I have hard water stains all over my window, I have already tried cleaning them with vinegar, does anybody know of any products which could remove them?
I live in a very hard water area, and when my glass shower screen needs cleaning I use Lime lite. It's one of the best products I've used for this purpose.
You can buy it in most supermarkets in a 500ml spray bottle.
The only thing that puzzles me in your question is, if the hard water stains are on the outside of your window how did this happen, as rain always falls as soft water?
Using of vinegar is the best solution for window cleaning and after applying the cleaners you can clean the window by using the paper. Rubbing the paper on the window screen smoothly can remove the dirt.
