Last time, we discussed how to prevent hard water stains on your windows and shower doors. The old saying “an ounce of prevention is worth a pound of cure” really applies here. If you have particularly hard water and aren’t diligent about removing the spots early, they can actually etch the glass making them nearly impossible to remove. Although, if it’s too late and you already have these unsightly stains, there are some non-caustic home remedies worth trying before hitting the hardware store for a cleaner that uses a lot of harsh chemicals.
One popular option is a 50/50 mixture of white vinegar and water. Put the mixture in an empty spray bottle and apply to the glass. Let it sit for a few minutes and wipe off with a clean cloth. This method works well for minor stains and spots.
For tougher jobs, a paste made from baking soda and water may be effective if left on the glass for about 15 minutes then wiped off with a wet towel. But beware, this method requires significant elbow grease! Applying this paste and completely removing it so there are no foggy areas can be a strenuous process.
If the home remedies haven’t removed the spots, it may be time to talk with your local glass company about a more robust commercial product. Typically these are pastes that have stronger chemicals in them and they really do the trick. To stay safe, you should wear rubber gloves and carefully follow the manufacturer’s instructions on the containers. Lastly, there are companies that specialize in water stain removal from windows and shower doors. The cost is definitely less than full replacement of the glass but results can be mixed.
