Top Reason Why Grout Starts to Grow Mold

Mold is one of the last things you want. It is difficult to get rid of and can cause serious issues. It can also increase asthma symptoms and upper respiratory infections. The number-one place for mold growth is in your bathroom. The moist environment makes it perfect for this bacteria to grow. Going a little bit deeper, your tile’s grout in your bathroom is where you will see mold at first. Why is it that grout and mold seem to go together? These are the top reasons why grout starts to grow mold.

Grime From Body Oils and Soap Scum

The majority of bathtubs and showers have some tile. Where there is tile, there is grout. Your shower and bathtub encounter a lot of body oils and soap scum. The body oil and soap scum that wash off your body are the perfect food for mold. When your grout comes into contact with both of these items, it starts to grow mold.

To prevent growth from body oils and soap scum, you should wash your showers and bathtubs regularly. You can use any store-bought shower and bathtub cleaner. After cleaning your shower, you will want to wipe down the shower and bathtub with a dry towel or cloth to get rid of the extra moisture.


Leaving shampoo, soap, and other items on your tile and grout can lead to a moldy growth. This type of growth can be worse if these items are wet. Items that sit on top of other wet items tend to take longer to dry and can trap water. This extra moisture can lead to bacteria growth on grout if these items are sitting on tile.

To minimize the chance of mold growing from other objects, it is best to store these items elsewhere, like on a higher shelf. It is also a good idea to make sure that the item and tile are dry before setting the item down.

Broken Grout

Broken grout can cause mold growth. When grout starts to break down moisture can easily get underneath your tile and provide the perfect environment. The best way to fix this issue is to have your grout replaced every six months. Replacing grout will help your bathroom feel clean again.

Removing Mold From Grout

The best thing you can do when you start to see this type of growth in any part of your house is to take care of it. The longer you wait to get rid of it, the more damage it can do. You can clean it yourself with a bleach and water solution. However, this doesn’t always get rid of it completely. In order to get rid of mold completely, you need to find the source. In some cases, you may be able to find the source yourself, but most of the time you will need a professional.
