A water mark on a mirror is an inconvenient and unappealing sight in a home or car. Using glass cleaners on a watermark will only waste your time and money. Vinegar is a great cleaner for glass or mirrors. It can powerfully absorb things that can cause staining, and its cleaning power can eliminate most stains. A rag, a little water and a bottle of regular vinegar is all you will need to succeed in getting rid of the water stains on your mirrors.
Things You'll Need
Wipe down the surface of the mirror with a wet rag. This will remove any dirt or grime on the mirror's surface.
Put some vinegar on your rag. Use a generous amount. In this project, more is better.
Wipe the stained spot on the mirror with the vinegar-soaked rag. Apply slight pressure, as it does take a little force to make the spot come out.
You will probably have to repeat the steps about three to five times to remove the spot.
