Hard-water deposits can leave cloudy marks on shower glass after the water dries. Regular wiping helps limit the buildup. To remove existing marks, choose a cleaner that is compatible with the glass, coating and nearby finishes.
What causes hard water stains on shower doors and screens?
Before you can get rid of pesky hard water stains, it’s best to know what’s causing it. In short, hard water stains are caused by hard water. Hard water is essentially water that’s full of minerals like calcium and magnesium. Those minerals are what leave the cloudy film on a shower door. Other minerals like lime can build up too, which are more difficult to remove.
Stains occur with the onset of turning on your shower. As the water streams down the glass, minerals and residue from pipes can be left behind. As the glass dries, these deposits get left behind, leaving the infamous hard water stains. These stains can be problematic for the glass mostly due to aesthetics, but when it comes to the hardware, can lead to dullness and corrosion. Overtime, hardware parts like hinges will have to be replaced due to corrosion caused by hard water.
How to prevent hard water stains on glass and shower doors
When it comes to preventing hard water stains on glass and shower doors, prevention is the best method. There are a variety of methods to help keep hard water stains at bay and make prevention manageable. Below are 3 common methods.
Method 1: Squeegee after each use. This method requires an intention, yet brief routine of removing the water from your glass and shower doors after each use. When the water is wiped down after each use, it’s more difficult for minerals to build up on glass, so you can enjoy a shiny clean shower for longer.
Method 2:Use a daily shower cleaner. There are daily shower cleaners on the market that are gentle enough to be used after each shower, yet strong enough to be effective against hard water stains. After using the shower, spray the glass with a daily shower cleaner. Follow the instructions on the bottle and squeegee or wipe clean with a microfiber cloth.
Method 3: Install a water softener. This prevention method does require an investment, however for those with particularly hard water, it can be worth it. A water softener removes much of the calcium and magnesium from the water, so fewer mineral deposits are left on the glass as it dries.
What to do if stains persist
Sometimes stains do persist. If this is the case, consider the following:
- Reevaluate your water softener calibration.Water softeners are generally effective once installed. If you notice stains returning or persisting, consult your water softener technician. Your water softener may need to be recalibrated or replaced. If you have a water softener that requires salt refills, you may simply need to adjust the amount or frequency of salt that is added.
- Use products specifically for hard water. Not all commercial products work on hard water stains. If stains are stubborn, you may want to try using professional cleaning products and services designed to address these stains.
- Use gentle yet effective cleaners.It’s important to use non-abrasive and non-acidic cleaners on glass and frameless shower doors. Using cleaners that are too acidic or too abrasive can damage the glass and dull the finish on your shower’s hardware.
Methods to avoid
The internet has a lot of information available for removing hard water stains from glass showers. Not all of these methods are effective or even advisable.
Some methods like using abrasive scrubbers like steel wool are harmful because they can scratch the glass.
Other methods, such as using dryer sheets and soap-based cleaners, are ineffective because they’re often not strong enough to dissolve the stains. You’re likely to end up with a waxy, soapy mess and partially cleaned shower glass. Worse still, using lemon juice or highly acidic cleaners can be harmful. The acid from the lemons or the wax from the dryer sheets causes build-up and can negatively affect the look and longevity of your shower’s hardware.
If you need to tackle hard water stains on your frameless shower doors, don’t go at it alone.
