WHY DOES MOLD GROW ON MY BATHROOM CEILING?
Bathrooms are excellent places to grow some of your home’s worst enemies: mold and mildew. Excess moisture in your bathroom (or other areas of your home) causes mold and mildew to grow. Mold and mildew only need oxygen, a food source, and moisture to grow. Mold and mildew can damage the fixtures of the bathroom such as the drywall, trim, paint, doors, ceilings, and more because for the mold and mildew, these fixtures are a food source.
Most building codes now require a fan in every bathroom. Why? Because fans help ventilate the room, remove bad smells, and remove moisture. The most important function of the fan being to remove moisture. Even if the bathroom has a window, a fan is the best way to prevent moisture buildup.
Keeping your bathroom dry, well ventilated, and consistently using an exhaust fan is critical to preventing mold and mildew growth.

IS BATHROOM CEILING MOLD REMOVAL A DIY PROJECT?
Removing mold can be a DIY project, but it’s a good idea to know when to call the pros. Our tips for mold removal help you know what to use, and what not to use. We can help you remove the mold safely, whether you choose to DIY or call the professionals. We want to help you get back to living your best life with a clean mold-free bathroom!
What Not To Use – Bleach
The goal of mold cleaning is not to kill mold, or even to disinfect a surface or material, but rather to remove mold from a surface. Think of mold more like dirt. If you had a wall with dirt on it, would you simply spray it with bleach and consider it cleaned? Of course not.
Bleach is a combination of chemicals used to kill bacteria and whiten clothes, floors, and walls. Bleach contains sodium hypochlorite which is toxic to bacteria, fish, and human beings. In fact, the Environmental Protection Agency (EPA) discourages the use of bleach and biocides for mold cleaning.3
Of course, there are more reasons to avoid bleach. Bleach is designed to kill bacteria, and will not completely remove a mold problem. Molds are fungi and they can, and will, grow back after bleaching.
What Should I Use To Remove Ceiling Mold In My Bathroom?
There are 3 simple ingredients you, probably already have on hand, that can safely use to clean away mold in your home.
What about all of the mold cleaners that are being marketed? What about the claims that a certain product kills mold, removes mold, removes stains, disinfects surfaces and prevents mold from ever returning? If it sounds too good to be true, it usually is.
There are 3 simple ingredients you can safely use to clean away mold in your home: white vinegar, baking soda, and hydrogen peroxide. Remember NOT to mix these ingredients! Keep reading for maximum cleaning power and safety!
Hard Surface Cleaning
To clean a hard surface (like a shower stall, tiles, toilet, sink, or floor), simply add hydrogen peroxide OR white vinegar to a clean, empty spray bottle undiluted. Never mix these chemicals! Choose one or the other.
When using hydrogen peroxide, spray the area to clean thoroughly, and let it sit for 10-15 minutes. Then, scrub the area, and rinse it clean with water. Repeat if needed.
For white vinegar, spray the area to clean thoroughly, and let it sit for at least 15 minutes or up to one hour. Then, scrub the area, and rinse it clean with water.
To use baking soda, add a teaspoon to a tablespoon of baking soda to a clean empty spray bottle and fill the bottle ¾ full of hot water. Shake to dissolve. Spray the area and use a scrub brush to clean the mold away. Then, rinse the area with clean water.
When using baking soda, it usually works best with a white vinegar spray following the baking soda, but not at the same time. The baking soda should be scrubbed away and rinsed before spraying with vinegar.
Baking soda is a base and vinegar is an acid. When they are used together, they react to form carbon dioxide gas and heat. The chemicals then are neutralized (changed to a neutral pH of 7) and have less cleaning power than they would if they had been used separately.
You can add 5 to 10 drops of tea tree essential oil to the white vinegar spray to increase the disinfectant power. Tea tree essential oil is distilled from the Melaleuca alternifolia tree from Australia. The essential oil is antifungal (kills fungi), antiviral (kills viruses), and antimicrobial (kills microbes, including bacteria). We advise people with allergies or asthma to use this oil with caution, as it can be irritating to the skin and lungs. To learn more about essential oils and how to use them safely check out our post: Essential Oils For A Healthy Home.
Cleaning Softer Surfaces
Hard surfaces generally are able to be cleaned, and most of the time mold will not grow back if it is completely removed and the moisture problem has been fixed. Soft surfaces (such as carpet, drywall, upholstered furniture, etc), are not always able to be cleaned completely enough to keep the mold from coming back. These types of material are such that the mold can easily penetrate making it difficult to remove.
Linens, clothes, and towels can be laundered in hot water to remove the mold, but stains may remain.
When you have softer surfaces such as carpet and drywall that have been contaminated with mold, it’s probably time to call a professional. It is very difficult to tell just how much of the surface has really been invaded by the mold just by looking.
Best Commercially Available Mold Removal Products
There are 2 commercially available mold removal products that we recommend. Both are cleaners that are safe to use in your home and near children or pets. Remember that you should always wear personal protective equipment when cleaning mold, no matter how safe your cleaner may be.
The first is Concrobium Mold Control Cleaner. You can check out the EWG’s Guide to Healthy Cleaning | Concrobium Mold Control Cleaner Rating here.
The other product we recommend has not been reviewed by EWG, however, it is an excellent and safe product that we can highly recommend. Bioesque Botanical Disinfectant Solution kills fungi and mold within 3 minutes. It also kills bacteria and viruses including COVID-19.
To learn more about this product and its safety check out the company’s website at: Bioesque’s Botanical Disinfectant Solution.
No matter what product you choose, be sure to wear proper safety equipment, ventilate the room to the outdoors, and follow all product directions.
It smells good. It’s clean, right?
Wrong! Smelling good does NOT indicate that something is clean! In fact ‘fragrance’ can be anything in a product that gives it a smell from essential oils from plants to industrial petrochemicals.7 Cleaning and personal care product manufacturers are required to list their ingredients on the label of the products.7 However, because of a loophole in government regulations (specifically the Federal Fair Packaging and Labeling Act of 1973), they are not required to list any fragrance ingredients.10 This means that they can use any chemical they choose to add smell to a product, including dangerous, allergenic, and even toxic chemicals.10 To learn more about hidden fragrance chemicals in personal care products go to: EWG Not so Sexy – Hidden Chemicals in Perfume and Cologne.10
Our government does not regulate personal care products or cleaning products in a way that allows consumers to have all the facts about a product before they use it.7 Because of this, we urge you to learn all you can before using any product in your home. Cleaning products affect air quality, especially if ventilation is not used during cleaning. Remember to always use good ventilation when using any cleaning product.
To learn more about the products you use to clean your home, and how they are NOT regulated by the federal government check out our article: Cleaning Products – Homemade vs. Store Bought.
WHAT TO WEAR TO CLEAN MOLD SAFELY
Before even choosing a cleaning product, you should know what kind of safety equipment to wear to clean a moldy surface.
The basic equipment consists of an N-95 respirator, goggles or eye protection, & protective gloves with long cuffs.15 Long pants, a long sleeved shirt and waterproof boots are important to wear as well.15 Closed toed shoes are a good substitute for boots, especially if you are working on a small area of mold.15
Mold is a respiratory irritant and allergen, so a mask with a N-95 respirator is important, especially if you know you are allergic to mold. A simple dust mask will NOT protect you from the mold spores.15 For more information about safety, visit: What to Wear before entering a Home or Building with Mold Damage by the CDC. To learn more about face masks see our post: In-depth Guide to Face Masks: Allergies, Grass Cutting, and COVID-19.
Tips For Cleaning Mold
- Remember that your goal is not to kill the mold spores, but to remove them. When they have been removed completely they cannot grow back.
- Ventilate, ventilate, ventilate! Ventilation is important during cleaning, so that any disturbed spores exit the building. Close and tape off doors to the rest of the house and use a box fan in a window pointing out while cleaning. This will prevent spores from invading the rest of the home, and remove them from the air of the room to be cleaned.
- Be sure to spray and then wipe all surfaces with a damp rag. Dry wiping will disturb spores and send them into the air! Airborne spores can regrow in new locations, and cause even more mold to grow. Mold spores are not visible to the naked eye, so be sure to cover all surfaces with your cleaner of choice, even if they look ‘clean’.
- Vacuuming is not the best method of removal. Do NOT use a vacuum to clean mold unless you have a vacuum with a HEPA filter. HEPA stands for high-efficiency particulate air, which means the filter can stop most particles of dust, pet dander, allergens, etc. that are 0.3 microns or larger and keep them from being put back into the air. The HEPA filter should be changed periodically to increase efficiency. Use with caution as mycotoxins may not be filtered out even when using a HEPA vacuum. Remember that you will eventually have to empty the vacuum, and it will be filled with the mold.
KNOW WHEN TO CLEAN AND WHEN TO CALL
Remember with mold or mildew, there are three steps to take for remediation:
- Clean what you can see. Baking soda, white vinegar, and hydrogen peroxide are excellent cleaners and can help remove the surface mold and mildew. For more information check out our posts – A Simple Guide to Cleaning Mold and How to Choose the Best Mold Removal Products.
- Prevent new growth. Keep areas of high humidity dry by ventilating rooms such as bathrooms, kitchen, and laundry rooms. Dehumidifiers may be helpful. To learn more about bathroom exhaust fans check out our post: Bathroom Exhaust Fans – All You Need To Know.
- Get a professional inspection if you suspect the problem may be more than an isolated area. If you see areas larger than about ten square feet, or there is a musty smell you can’t identify, it may be time to call the professionals. A professional mold inspection can ensure your problem is solved and not just covered up.
Remember, mildew is a surface dweller and easily removed. Mold grows inside of the food source (carpet, drywall, etc.), and can cause major health issues. If you clean an area and the fungal growth comes back quickly, you may have a mold problem. A professional inspection can determine the true source of the problem and fix it.
