You might feel like your shower curtains are beyond repair when discovering mold however, you can save them. Heres how to clean shower curtains:

Baking Soda

Common Causes Of Bathroom Mold

As previously mentioned, bathroom mold is often caused by a high level of humidity, which happens when you take a shower. However, humidity is not the only cause of bathroom mold.

Poor ventilation is another one. Most people close their bathroom door when they are showering. By doing this, they trap all the moisture-laden steam produced by a hot shower.

Since there is no airflow during shower time, moisture then attaches itself to the floor, walls and plumbings, giving mold the perfect conditions to grow.

The fact is that bathrooms are the wettest areas in a house, except maybe the basement. Even if you ventilate your bathroom properly, all the dampness caused by the water in showers, sinks, and even toilets, will eventually cause mold to grow. There is, of course, some extra water in bathroom mats and towels, which can easily become small mold heaven.

Last but not least, deteriorating caulk is another common cause of bathroom mold. When grout begins to crack, moist air from a steamy shower can easily find its way into the sides and back of your tile. With paint as a source of food, darkness behind the tile and now moisture, you might have a new pet hiding.

Dealing With Poor Ventilation And High Humidity

Since humidity is actually the main cause of mold, the first thing to be concerned about is ventilation. If you dont already have bathroom fans, now is the time to get and install them. Keep your fan on for up to 30 minutes after each shower. Opening the door and windows will do the same trick if, for any reason, you cannot afford this investment right away.

We have already mentioned that keeping the bathroom door closed while showering can increase the chances of mold growth in your bathroom. In case you still do not want to shower with the bathroom door open, or it is too cold to open a window, you should opt for a strong and effective exhaust fan that will compensate for this. Mechanical exhaust is crucial in controlling and expelling excess humidity caused by showers.

Of course, leaving the window open will not help you if you live in a humid climate. If this is the case, you will have to rely on dehumidifiers to prevent mold. They are often inexpensive and freestanding, which lowers the installation costs. It is very important to keep in mind that mold needs as little as 55% humidity to grow, so do make sure that your dehumidifier is set right or you may still have a problem.

Bathroomsespecially shower stallsare a perfect breeding ground for mold. They are humid, often dark with poor air circulation, and there is food readily available from soap scum and body soil. What can begin as a tiny mold colony creeping along a grout seam can grow into a moldy ceiling.

Before you begin, it is important to determine what type of mold is growing on the bathroom ceiling. Molds are classified into three categories:

  • Allergenic molds can require removal by a professional, but most allergenic molds can be removed with home disinfecting products.
  • Pathogenic molds can be controlled with disinfectants but large colonies require professional removal.
  • Toxic molds are the most harmful and require a professional to kill the mold and dispose of any affected materials.

Once you have discovered and identified the mold, it must be removed. If the mold infestation is deemed to be toxic or covers 10 or more square feet, then a professional should handle the removal. Local public health departments can offer advice on mold testing and refer you to an expert mold remover.

Tip 7 Install A Bathroom Fan

Remove black mold from bathroom ceiling and walls fast!

Most of the time, mold on bathroom ceilings is caused by typical bathroom humidity. Mount a bathroom fan thats linked to your bathroom light fixture. That way, when you switch off the bathroom light as you leave, the fan automatically kicks in. This is especially helpful for night-time showers. Its also useful if you frequently forget to turn on the bathroom fan.

The fan should have a timer to avoid power wastage. Your local plumber or hardware store attendant can guide you on the right fan size, speed, and brand for your bathroom. Deciding factors include physical size, the number of people who share the bathroom, and how often the bathroom is used. Does mum enjoy her daily soak or does everyone take 10-minute showers?

If the bathroom is used frequently and shared by more than four people, invest in a constant-flow fan. It runs throughout the day so its more effective for a high-traffic bathroom. Some of these fans have intermittent timers so the fan will consistently switch itself on and off. It could be speed-based or moisture-based and it goes on or off depending on how wet the bathroom is.

How To Clean Mold From Bathroom Tiles

Scrubbing with vinegar or a borax solution is a great way to clean mold from bathroom tile. For small applications, mix 2 tablespoons borax into 2 cups warm water and funnel into a spray bottle. Spray the solution on tiles and let it sit for a few minutes. As noted earlier, you can also make a large-batch tile cleaning solution with 1 cup borax and 1 gallon of warm water. Use a mop or sponge to scrub away the mold. Whether you use vinegar or borax, there is no need to rinse the solution. However, you will want to dry the floor so the moisture doesn’t encourage the mold to return.

To clean mold from bathroom tile grout, use the same borax or vinegar solution as before. Apply it directly to grout lines and let it sit. Use a toothbrush or another small bristle brush to clean mold from bathroom tile grout. For hard-to-remove stains, mix two parts baking soda with one part vinegar to form a paste. Apply it to the grout and let it sit a few minutes before scrubbing away mold. If desired, you can also use a commercial grout cleaner.

Editor’s Tip: Check your tile material before using one of these solutions. Vinegar can be damaging to some tile materials avoid if you have marble, slate, granite, or stone tiles.
