WD40 can be used to clean windows.
WD40 works to clean almost anything off of windows when the regular window cleaning solution doesn't work.
Spraying WD-40 on glass or windows will enable you to safely remove almost anything -- stickers, tape, the stubborn adhesive of price labels -- from a surface.
WD-40 works on all glass surfaces, including windows, mirrors and tables.
Just be sure to wipe it off after using on glass to prevent streaking and staining.
You can also clean windows and glass with vinegar and water as vinegar and water make a nice window cleaning solution.
Ammonia and water can also work to clean windows as well.
WD-40® Multi-Use Product is great when it comes to mirror cleaning and water spot removal.
It is easy to use and all you have to do is spray the liquid on to the affected area and wipe it clean with a clean cloth.
It will leave your glass windows and mirrors sparkling clean and as good as new.
