Causes of Household and Bathroom Mold

How to remove mold from bathtubAll mold is a type of fungus and requires a food source and moisture to grow and thrive. Food sources for mold usually come in some sort of organic material so paper, porous plastics and wood are all hospitable breeding grounds for mold. Most home mold infestations are caused by prevalent moisture and can be onset by floods or periods of heavy humidity. Biological pollutants are also a contributing factor so eradicating bathtub mold means first identifying the source.

It’s often advisable to have internal air ducts inspected for mold or moisture and some people prefer to have a complete window and door inspection as well to ensure moisture isn’t seeping in undetected. Specific causes of mold in your bathtub may include porous grout that sucks up excess moisture and areas that don’t drain properly, creating puddles of water that are perfect for mold growth. Some homeowners may find that the longer they go without a regular bathtub cleaning, the more likely black mold is to show up on their tub surfaces.

How to Remove the Mold and Disinfect the Area

Once you’ve identified bathtub mold, removing it is a simple step-by-step process.
Step 1: The first step is to thoroughly dry the mold in your bathtub which means wiping the surface of your tub and sealing off your bathroom to any excess moisture. Different types of mold respond to different cleaning agents but if you have black mold in your bathtub, the most common infestation, a simple bleach solution should suffice.

Step 2: Mix bleach and water together to form a solution then while wearing rubber gloves and goggles, thoroughly wipe the surface of your bathtub to kill all remaining mold. It’s imperative never to mix bleach and ammonia as this can be hazardous.

Step 3: After scrubbing the bathtub clean with a plastic brush and bleach, use pure water to rinse down the area to ensure all mold and cleaning agents are removed from the surface. If cleaned properly, a visual inspection of the area should determine the mold has been removed.

Step 4: The final step of your bathtub mold removal is to then thoroughly dry the bathtub then make sure no moisture re-enters the room for at least 24-hours. The combination of decreased moisture and bleach should thoroughly remove the mold in your bathtub as well as disinfect your bathtub area.

Tools and Protective Gear for Mold Removal

When working with mold and cleaning agents it’s important to have the proper safety equipment. Aside from rubber gloves it may be necessary to invest in rubber boots, plastic goggles and even a mouth and nose mask. This is to ensure you don’t breath in any hazardous chemicals as well as mold spores. It’s best to use a stiff brush to clean the black mold in your bathtub and any porous items used in the cleaning process like a rag should be thrown out when cleaning is completed.

Warnings for Safe Mold Removal:

As previously stated, never mix ammonia and bleach together as this combination can produce hazardous fumes. It’s also advisable to open any windows and doors in the room you’re cleaning to avoid inhaling as much bleach as possible. Never touch bathtub mold with your hands and always use rubber gloves when dealing with cleaning agents. As always, when working in a bathroom setting, wear rubber soled shoes or boots to avoid slipping and falling.

Tips for Preventing and Detecting Mold

how to get rid of mold in bathtubPreventing mold in your tub is often easier than the process of bathtub mold removal. The first and most important step in mold prevention is eradicating excess moisture which may mean having your bathroom inspected for ventilation issues. Leaky windows and doors as well as a faulty air-conditioning ventilation system may mean your bathroom is moister than it should be which leaves mold rife for growth.

Another crucial step in moisture prevention is to stop any condensation from forming, so check your room thoroughly to ensure no moisture beads are forming, even if they happen on hard surfaces. Porous and organic surfaces are perfect locations for mold to grow, so make sure all parts of your bathtub are properly sealed. Cracks and crevices make great surfaces for mold so consider resealing your bathtub if necessary to make sure its surface consists only of hypoxic plastic or hard sealed tile.

The last step in black mold prevention is regular cleaning – you should aim to thoroughly bleach clean your bathtub at least once every three months to inhibit new mold growth and kill any existing mold. The easiest way to tell if mold is present in your bathroom is by taking a moment to visually inspect all surfaces and also to smell test for musky, dank odors. A professional may be needed to determine exactly which type of mold is present in the home.


Mold is a common household infestation and can usually be taken care of rather easily with a few home products. If you suspect the mold in your bathroom is something other than standard black mold or if after removal your mold returns you may want to call on a professional to give you advice. If untreated, some strains of mold can be hazardous to respiratory systems and can spread further than the eye can detect so if you’re doubtful you’ve thoroughly removed the mold, consult an expert.
