How To Remove Mold Mildew From Shower Grout

How To Get Rid Of Mildew

How to remove black Mold & Mildew from shower tile grout- Easy way!!!

Weve written a guide for How to Clean Mold, and now its time to tackle its ugly cousin: mildew. Mildew is typically white or gray, appears flat like a film, and feels like dry powder. While mold can grow on food and damp surfaces, mildew forms in humid and poorly ventilated areas like bathrooms, windows, attics, and basements.

Unlike black mold, mildew can easily be wiped off surfaces, especially nonporous ones. But simply wiping away mildew doesnt always fix the problem and does little to keep mildew from returning.

Thats why its important to take preventative steps and learn how to get rid of mildew once and for all. Dont worry, with a little bit of elbow grease and common cleaning supplies, youll be able to get rid of the mildew in no time. Although it may seem like the easiest solution, we advise you to avoid using bleach because distilled white vinegar does the job better without harsh chemicals.

Why Do You Need To Clean Mold From Bathroom & Shower Grout

So, is it really that important to clean the grout in your shower and bathroom? Does mold make that big of an impact or should you keep the grout clean simply for aesthetic reasons? There are actually several reasons why it is important to stay on top of the mold growth that so quickly accumulates on the grout in your bathroom and shower.

Why Do I Have Mold In My Shower

Its very common for mold to be found in the shower. There is lots of water and humidity in the bathroom which mold just adores.

Frequently running water in the shower creates wet surfaces and puddles of water. If you dont dry this moisture out quickly it can easily lead to mold growth.

On top of this, when the water in the bathroom does dry out it evaporates into the air and increases the humidity. Steam from the shower or a hot bath also makes the bathroom more humid. Since bathrooms are often not well ventilated the humidity tends to hang around and wet surfaces take a long time to dry out. Enter mold.

Another reason mold grows in theshower is because grime from body oils and soap scum which is washed off andonto the shower or tub create a food source for mold to feed on.

Basically, if mold were to have achoice vacation destination it would be the shower. Soooo inviting.

Use Baking Soda Or Borax

Baking soda and borax are both alkaline substances. Mold doesnt like that. Mold prefers to grow in slightly acidic environments instead. Because of this, you can use baking soda or borax to kill mold and then scrub it off.

There are three ways to do it:

  • Make a borax or baking soda paste with a bit of water and apply it to the moldy grout. Let it sit for about 15 minutes, then scrub the area with a brush and rinse it with water.
  • Apply some borax or baking soda powder directly to a damp cloth and use that for cleaning the grout.
  • Mix 1/2 cup of borax or baking soda with a gallon of water. Use a spray bottle to apply the solution over the mold and mildew. Let the mixture sit for about 30 minutes. Then, use the scrub brush and rinse it with water.

Remember, baking soda is abrasive. You should avoid scrubbing your tiles directly with a baking soda mixture. If youre going to use this cleaning agent, use a thin brush or toothbrush.

Eliminate The Mold Triggers

How To Remove Mold And Mildew From Shower Tile Grout

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.

    Are There Any Preventative Steps I Can Take To Stop Mildew From Forming In Between Tiles In The First Place

    Yes! One of the best ways to stop mildew from building up in between shower tiles is to apply a sealant or caulking whenever it necessary. Reapplying caulking along the edges of the tub, or adding a layer of sealer between tile grout after a year or two of use will close up any openings and leave less space for mildew to grow.

    You can also spritz the shower with vinegar and water after every shower or two as a no scrub homemade shower cleaner. This leaves less opportunity for mildew to form and only takes a minute or less a couple of times a week.

    Where Does Mold Grow In My Shower

    • Mold can grow in the grout. That is one of its favorite places.
    • It can grow inside the window frame if your window is IN the shower like mine is.
    • It can grow around the drain and on the drain plug.
    • Mold can grow on the shower caulking.
    • It can grow in the door tracks if you have doors.
    • Mold can grow under shampoo bottles, bars of soap, shaving cream bottles, etc
    • While not technically a part of the shower, mold can grow on a shower curtain.

    Mold can also grow behind shower tiles and on the wall but this is due to a leak behind the shower and not from water in the shower typically. The exception is if your grout is old and cracking. Then water can seep behind the shower tiles allowing mold to grow.

    Best Way To Remove Mold And Mildew From Tile Grout

    As a bathtub re-finisher, I am constantly asked how to remove mold and mildew from around the tub and within the grout lines on the tile surround or inside a shower. It is actually black mildew that we are fighting and its not an easy fight.

    Mildew binds itself to porous areas and areas that give it a surface to cling to such as silicone caulk. When you have mildew on the caulk between a bathtub and the surround it is best to remove it and just start over with a non-silicone caulk with a mildew resistant micro-ban additive.

    Take a utility knife and score the old caulk length-wise from the top and from the side repeatedly until you have the majority removed. Then take your window scraper razor blade and go after the rest. Before you caulk it back in get all the nearby mildew removed as well.

    Mildew thrives in a higher PH environment. Soap and minerals have higher PH levels and thus encourage mildew to grow. Staying on top of soap and minerals is the way to keep mildew at bay and this is done with a more acidic, lower PH cleaner such as Barkeepers Friend, which I highly recommend.

    The key to removing mildew is by keeping a strong bleach solution on top of the affected area for a good amount of time. Having a strong grout brush is also important to impregnate the solution into the grout and work the mildew loose.

    Stay at it and you will get rid of that mold and mildew in your grout!

    Use the previous technique of spraying the solution and then wiping it clean to remove the mold that appears on the surface. Next, respray the grout and scrub with an old toothbrush, scrubbing pad, or scrubbing brush.

    Ensure Proper Ventilation While Using Cleaning Products

    Proper ventilation is of the utmost importance when dealing with mold or strong cleaning agents. If you are able, open any windows and doors in the bathroom to ensure ventilation. Always use the exhaust fan during and after your cleaning process. If the bathroom does not have an exhaust fan, it may be wise to use a small fan to direct airflow out of the bathroom.
