Shower doors make up an integral and large part of your bathroom's aesthetic. However, because they are constantly exposed to high levels of humidity and heat, they can develop mildew and mold growth on them over time, which not only ruins the appearance of your door but also poses a fairly serious health hazard. Thankfully, there are a number of things which you can do to prevent mildew from growing on your shower door.

Dry Off the Doors

Perhaps the most obvious step, but also the most effective, is to use a towel to dry off condensation and collected water on your shower doors after you use the shower. This helps prevent mildew from gaining a foothold on your shower door.

Run the Fan

Another simple way to reduce overall humidity within your bathroom and make it less likely for mildew to begin to grow on your shower door is to run your bathroom's fan after using the shower to increase the amount of ventilation that your bathroom receives. If you don't have a fan installed in your bathroom, you can increase the ventilation in your bathroom by opening a window to allow fresh air to enter the room.

Leave the Doors Open

After taking a shower, it's also a good idea to leave the shower door open to allow air to circulate into the shower – this will reduce the amount of humidity and moisture within the shower enclosure. This is especially effective if you have the fan running or the window open at the same time. In a similar vein, it's also a good idea to leave the door to the bathroom propped open to allow even more circulation to occur.


If mildew growth does occur on your shower door, you don't need to worry or replace the door entirely. Instead, you can treat it to remove it, and begin to incorporate the above prevention techniques to prevent mildew from reappearing.

Simply mix a solution of four parts of warm water to a single part of bleach in a large bucket. Be sure to wear gloves to protect your hands. Apply the mixture to the mildew on your shower door using a sponge or a brush. Scrub thoroughly until all visible mildew has been removed – you may want to use an old toothbrush to clean hard-to-reach areas, like the metal tracks and hinges of the door. For more information, contact professionals like Aladdin's Glass & Screen Products Inc.
