Using A Vinegar Solution
Types Of Water Spots And Stains
Normal Spots
Typical water spots are sometimes formed whenever hard water leaves a mineral residue on the windows of your vehicle. These minerals are usually magnesium, calcium, or something similar.
Unfortunately, water from any source can cause these spots, including rainwater, sprinkler water, or even water from certain car wash services! Over time, the deposits of these minerals form sort of like line scale and end up causing a lasting water spot that doesnt go away without significant treatment.
Etched Stains
Etched water stains aren’t caused by regular mineral deposits. Instead, these stains are caused when puddles or small pools of water are exposed to intense heat or high amounts of sunlight over long stretches. As the temperature of your cars windows gets higher and higher, the water spots can eventually become etched into the glass. This is one of the reasons why its important to thoroughly dry your vehicle after washing it you really cant just leave it out in the sun to dry.
Etched stains are among the most difficult to remove, and may require professional help or abrasive removal techniques like wet sanding.

Will Rubbing Compound Remove Water Spots
Rubbing compound is a great solution for removing difficult water spots 0n your windshield. Rubbing compound is a mild abrasive that will wear away the mineral deposits that water spot removers are unable to break down.
You can use a rubbing compound by hand or you can use a random orbital polisher to take a lot of the manual labor out of the job.
Some people even use polishing compounds to remove fine scratches from automotive glass.
Whether you use rubbing compound by simply applying it to a microfiber polishing pad or a dual action polisher, it should make fairly short work of difficult water spots.
I wouldnt recommend this as your primary method of removing water spots on glass but it is a great alternative for difficult spots. Its especially good if you already have a polisher and compound handy.
