Windows can accumulate hard water stains over time, especially if you live in an area with hard water or use hard water, such as well water, to water your lawn. Hard water stains are caused by minerals in the water, such as calcium and magnesium, which can leave unsightly spots and streaks on your windows. Fortunately, there is a simple solution for removing these stubborn stains: Barkeepers Friend.

Barkeepers Friend is a powerful cleaner that is effective at removing a wide range of stains, including hard water stains. It contains oxalic acid, which is a mild abrasive that can break down and remove mineral deposits from glass surfaces. Here’s how you can use Barkeepers Friend to remove hard water stains from your windows:

1. Prepare the Window: Before you begin cleaning, make sure your windows are free from loose grit or dirt. Rinse or wipe away surface dust so you don't grind grit against the glass.
2. Apply Bar Keepers Friend: Using a damp non-scratch pad, sponge, or cloth, apply a small amount of Bar Keepers Friend to the wet glass. Work in small, shaded sections so the cleanser doesn’t dry on the pane before rinsing.
3. Scrub the Surface Gently: Using a white non-scratch pad or soft scrubber, gently polish the mineral-stained glass in circular motions until the calcium and magnesium deposits dissolve.
4. Rinse Thoroughly: Rinse the glass completely with clean (preferably pure RO/DI) water to remove all traces of the cleanser.
5. Squeegee and Detail Dry: Finally, use an Ettore squeegee and a lint-free surgical huck towel to dry the glass and frames completely, preventing new water spots from forming.

In conclusion, Barkeepers Friend is a highly effective cleaner that can be used to remove hard water stains from your windows here in Florida.
