Tips To Prevent And Remove Mold From Grout Lines

House Cleaning Techniques : How to Clean Bathtub Grout & Mold


What does it take to keep your bathroom sparkling with cleanness at all times?

Its a well-known fact that mold thrives best in warm, moist areas with poor air circulation. This makes bathrooms, kitchens, laundry rooms, and basements ideal places for mold to develop humidity is always high and air flow is usually limited. Therefore, it is very common to see mold in these rooms on walls and ceilings, on caulking and between tiles, etc.

Tile grout, however, is where mold is most often found. There is a good reason for that tiles are typically used in areas where moisture is abundant and the porous nature of grout makes it particularly susceptible to mold growth.

When mold builds up on the grout, it not only makes your kitchen or bathroom look old and dirty, but also poses serious health risks to you and your family and compromises the integrity of your home.

To prevent such troubles and save yourself a lot of money and nerves, you need to find an efficient way to keep mold at bay remove it from the grout as soon as you notice it or, even better, prevent it from developing in the first place.

Mold And Bathtub Materials

Bathtubs are made from different materials and you need to understand how to clean without damaging the bath. You should use a commercial cleaning removal solution on a porcelain enameled steel tub. Do not use bleach or vinegar. When cleaning an acrylic tub you need to use a soft cloth and plenty of water. These tubs usually only require a gentle cleaner and should be dried completely, especially around the drain. You can clean a fiberglass tub using a variety of cleaners. Use the vinegar solution for removal of mold and grime and rinse with water. When cleaning enameled cast iron, you need to be careful so you dont discolor the surface. A mild commercial cleaner will work well the removal of stains and be sure to rinse completely and dry.

Eliminate The Mold Triggers

Removing the mold is just half of the job done. If you will not change the environment in the shower, it is a matter of time until the mold will form again. For this reason, it is essential to detect what was the cause of mold growth and try to limit it.

Here are the two essential factors that might be the cause of the mold in your shower: humidity and pH.


If you have mold in your shower, you are probably dealing with a hydrophilic mold type such as Stachybotrys , which needs high water activity to grow. Because of that, it is essential to limit the moisture to a minimum. Here are a couple of tips, how to achieve it:

  • Install a bathroom exhaust fan above the shower. It should help to remove the humidity from the bathroom.
  • Take cooler showers to limit the steam. It is a money-saving and healthy option.
  • Use a squeegee to remove water from the walls after you take a shower. It will help the walls to dry quicker, which should hinder the molds growth. As a bonus, you will decrease the amount of soap scum that might build up on the walls or shower doors.
  • pH

    As it was stated earlier, mold thrives in pH 3 7. Changing the pH of the grout will help you to create a hostile environment for the mold. For this purpose, from time to time, pour a solution of baking soda and water onto the shower walls where the mold used to form. This way, you will protect the grout from the potential future mold build-up.

    Purify The Grout Area With White Vinegar

    Vinegar is a natural cleaning agent and also doesnt cause discoloration of grout like chlorine. Spray white vinegar on the moldy shower grout and allow it to settle for 30 minutes. Then scrub the grout with a stiff brush. Again spray white vinegar and keep it for 30 minutes on the grout. Now rinse the shower grout with warm water. If it is necessary then repeat the process to clean the area thoroughly.

    How To Prevent Shower Mold

    Mold is more likely to start growing the longer water is left standing on bathroom surfaces or stays soaked into porous materials such as bath mats and towels. Proper cleaning, ventilation and drying practices are crucial for keeping mildew or mold from forming in a shower.

    Make sure your bathroom has a functional exhaust fan rated for the size of the room. Ventilation fan performance is measured in cubic feet per minute. For home bathrooms, 1 cfm per square foot of floor space is a good rule of thumb for selecting a fan with sufficient power to draw out moist, warm air. In bathrooms larger than 100 square feet, add 50 cfm for each toilet, shower, bath or combination installation.

    Always run the fan after bathing or showering to speed up drying. Fungi thrive in environments with consistent sources of moisture and nourishment that are not frequently disturbed. Regularly spraying on a mixture of vinegar diluted in water and lightly scrubbing and wiping bathroom surfaces and grout can keep mildew or mold from gaining a foothold.

    If a mold problem keeps returning in spite of DIY cleaning and prevention efforts contact a remediation expert near you. Professionals trained in the latest remediation standards can address the causes of mildew or mold growth and keep an infestation from spreading throughout a home or workplace.

    Ways To Prevent Shower Mold

  • Practice good ventilation. Open the bathroom window when showering. Turn on the exhaust fan when showering and leave it on for 30 minutes afterwards. Keep the bathroom door open when showering if possible.
  • Shower drains contain biofilm and cellulose materials such as soap scum, body hairs, and oils and lots of moisture so they can be a breeding ground for black mold. It is important to keep drains open and clear of cellulose materials. Remove any hair after showering and pour a little vinegar down the drain weekly to keep the drain clean and prevent mold spores from developing.
  • After showering wipe down the entire shower including all your shampoo and soap bottle.
  • Once a week spray the shower with EC3 Mold Solution Spray to kill any new mold spores that may be trying to root.
  • Clean your shower from top to bottom every 14 days at a minimum. Weekly is better but no one has time for that! So shoot for every two weeks.
  • If possible, DO NOT USE one of those suction cup non-slip mats in the shower. Those are a mold magnet.
  • Treat your shower with Endurance BioBarrier every 6 months to prevent mold growth. You can read how and why Endurance BioBarrier works here.

    Does This Leave Residue

    I have ever had issues with residue in all the ways I have used this solution, but a reader commented recently she had to rinse it many times to get the baking soda haze off. If you are using this on a different type of grout that isnt sealed or is much more grainy, just follow up with hot soap water. Or you can also spray rubbing alcohol on the area. Each time I use this solution, there is almost nothing left after I scrub the area. If there seems to be a little pigment left from the baking soda, dont worry, it also can wear off even just after a few hours.

    I just wanted to add this tip in there if anyone had concerns about this.

    Here is a very common thing to see. My old mid-80s white tile in my guest shower and bathroom has accumulated black mold over the years. And of course, I have been lazy at cleaning it, and my roommates I had didnt clean it either.

    Normal shower and bathroom cleaning mold and mildew removable sprays would not work. All the scrubbing in the world wouldnt work.

    To use the gel, remove the cap, and then squeeze a bead of gel over the moldy areas. The gel will stay put. Then all you do is allow it to work its magic. Allow it to stay on the black mold for at least 5 hours, you may need to let it stay even longer.

    This black mold spot on my shower tile had been there for many years. So I left the gel on for about 8 hours.

    The results were absolutely remarkable. Years of caked-on hard-to-clean, stubborn black mold, gone. Next, all you do is wipe it off with a damp paper towel or washcloth and then rinse it really well.

    There you have it, method 1 is a super success for this particular type of black mold situation.
