Mold in Shower Door: How to Get Rid of Them? (Answered)

Have you ever spotted black gross looking chunks in your shower door? They are molds. You may ask why molds grow in the shower area and how you get rid of these unwanted guests.

We’ll let you know the reason as well as the solutions here!

What causes mold in the shower door track or seal?

High humidity and moisture are mainly responsible for molds in the shower door track or seal. The shower area is more or less damp due to water splash and so molds grow there since that place lacks proper ventilation. Old and cracked seals too can produce molds as they can’t prevent water anymore. 

It’s really a matter of stress when you spot molds in different colors in your shower door or in between the seals. It surely ruins your shower experience and gives a gross feeling.

You might think about how these molds grow here even though the shower area, especially the door, is always being cleaned with water spills.

Well, that’s where you go wrong. Even if you think the water and sap we use in the shower area can keep the place neat, it actually doesn’t.

Instead, this is one of the reasons for mold build-up in your shower door track and seal. Because a moist and humid environment is what lets molds grow.

Molds love to be in a warm, damp ambiance and the shower area is one of those spots. When we take shower with hot water the closed door place traps the warm humid air as well the water gets in the door track. If the door seal is old or cracked, it also grabs some water.  

Since most of the time, our shower places aren’t well ventilated the water, moisture and humidity can’t go away. Thus the places especially the door tracks and seals become a habitat for molds.
