Shower grout mildew is among the most common problems homeowners have to face. While this type of mildew can be a pain to get rid of, there are a number of effective ways to prevent it from forming in your bathroom. Below are the steps you will need to take to ensure that your bathrooms remain mildew-free.

Step 1 - Let Moisture Escape from Your Bathroom

Moisture given off by hot showers is the chief cause of mold and mildew formations in bathrooms. Thus, one effective way to prevent shower grout mildew is to allow the moisture to promptly exit your bathroom, and there are several easy ways to go about this task. First off, you can leave your bathroom door partway or fully open while showering. This, in turn, will provide the moisture with an easy path through which to exit the bathroom. Another simple way to go about this is to open up one of your bathroom windows whenever you're taking a hot shower, as this will have essentially the same effect as leaving your bathroom door open. However, opening up a bathroom window is only advised if you live in a safe neighborhood and a warm-weather environment.

Step 2 - Force Moisture Out of Your Bathroom

If you have a propensity for taking long, hot showers, simply leaving your bathroom door or window open may not be enough to get rid of all the moisture. With that in mind, it is generally a good idea to force the excess moisture out of your bathroom. One of the simplest ways to do this is to place a fan in one of your bathroom windows and set it to exhaust whenever your shower is in use. Alternatively, if your home features a bathroom-based exhaust fan, it is recommended that you run them whenever a hot shower is underway.

Step 3 - Limit the Amount of Time Spent in the Shower

While it may seem fairly obvious, placing a limit on the amount of time you and your family spend in the shower each day is another good way to prevent shower grout mildew. In addition to saving you a fair amount of money on water and heating bills, making sure that showers, particularly hot ones, last no more than 5 to 10 minutes can go a long way in impeding the formation of shower grout mildew. This method of combating mildew is particularly effective when combined with steps 1 or 2.

Step 4 - Regularly Clean Your Shower Grout

Even if you utilize the previously discussed steps, regular cleanings are the most sure-fire way to prevent the formation of shower grout mildew. Once every week, take care to spray your shower grout with a commercial grout cleaner and vigorously scrub it with a small scrub brush or expendable toothbrush. If your bathroom features an exhaust fan, however, you may be able to get away with biweekly cleanings.
