How Can You Clean Mold Off Walls

Know Your Mold And Mildew

How To kill Surface Mold Off Walls

Mold can grow in your home wherever theres an abundance of moisture, especially when its allowed to remain for extended periods of time. Mold usually appears on walls, ceilings and floors of homes where moisture management is not at its best. In particular, basements, shower walls and windowsills are areas where mold commonly likes to live. Mold and mildew, for all intents and purposes, are essentially the same thing mildew is generically used to describe many minor mold problems in the home, such as on shower tile grout. However, some molds can become highly toxic to people if left to prosper. Mold can cause allergic reactions, asthma and other respiratory complications, and is especially a risk for small children, the elderly and those with existing respiratory illnesses or weakened immune systems. Mold can appear in many shapes and colors, none of which accurately determines the actual species of mold. However, it does commonly present itself in various tints of black, white, green or blue, and in many combinations of these and other colors.

How To Remove Mold From Bare Drywall

If you spot mold on your drywall, it may indicate a larger mold problem in the stud space behind the drywall. And, mold on drywall has already penetrated the surface, so you cant simply wipe it clean. You will need to cut it out and replace it in this case. Follow these steps:

  • As with the painted walls, you will want to move everything away from the area and use plastic on the floor to protect it.
  • Youll need something to attach the new piece of drywall to, so use a stud finder to locate the wooden supports behind the wall.
  • Use a utility knife to cut out the section you marked. Do not use a power saw, as this can agitate the mold and cause the spores to get into the air.
  • To limit spread of mold spores, carefully remove the drywall piece and place it mold side up on the plastic.
  • Clean the cavity with mold cleaner to make sure youve gotten it all, and dry it thoroughly.
  • You will want to make sure your new piece of drywall is the same size as the one you cut out, so measure the length and width of the missing section of drywall and cut the new section to those measurements.
  • Attach the new piece of drywall with screws, apply a joint compound to patch seams, let it dry and sand.
  • Wrap up soiled materials in the plastic and throw it away.
  • Vacuum the room with a HEPA vacuum.

    Keep The Humidity Low

    A humid environment can encourage mold regrowth in the future. Do your best to keep the space dry and mold-free by minimizing the humidity levels. Use a dehumidifier to keep the humidity between 30 and 50 percent to deter mold from growing in other areas.

    Following these steps will help you remove mold from your drywall surfaces and discourage it from growing back.

    Is Bleach Baking Soda Or Vinegar Better To Kill Mold On A Wall

    Lets look at each individually.


    Most homeowners believe that using bleach on walls, will kill mold and solve their problem.

    But thats far from the truth.

    Even the EPA recommends against using bleach for routine removal of mold from walls and other porous surfaces.

    Bleach can remove mold found on hard plastic, metal, and another non-porous surface.

    But you should always be cautious when using bleach or other biocides because they can be worse than the mold itself.

    Using bleach on walls is ineffective.

    This is because the chemical makeup of bleach prevents it from penetrating below the surface of the wall where the roots of the molds are located.

    When you apply bleach directly to mold on a wall, it may kill the spores and growth on the surface.

    However, it will have little to no effect on killing the root system growing below the surface of the wall.

    Spraying bleach on a wall with mold will be like watering your grass.

    Remember this, whenever you see mold growing on an item, the roots have already been established deep below the surface of the material.

    I can tell you first hand what will happen when you try to use bleach to clean mold from the surface of a wall- a porous material.

    What happens?

    It comes right back every time if you dont fix the problem in the first place.

    So, to sum it all up Dont try to use bleach to clean mold from your walls.


    There is some good science behind this claim.

    The key is the contact time and using a little elbow grease.

    What To Do If Mold Persists

    If the mold stains still remain, the wood surface will need to be sanded to remove the spores that have deeply penetrated the wood. If you are not familiar with wood sanding or refinishing, ask questions at a home improvement store about the right sandpaper grit to use for your situation. After sanding and vacuuming away all of the grit, the wood should be refinished or sealed to help prevent future damage.

    Using Bleach To Remove Mold

    You can spray the bleach directly onto the moldy areas of the tiled walls. However, bleach can cause colored grout to become faded, so be wary of that result. After applying the bleach, allow it to sit. After at least 30 minutes, grab a stiff brush to scrub the bleach. Then wash off the cleaner with warm water.

    Bleach is a harsh product, so not everyone likes to use it. If you prefer more natural mold removal for tiled walls, distilled vinegar is a great option.

    Mold Removal From Fabric

    How to clean mold off bathroom wall? : howto

    Its easier than you might think for clothes to attract mold and mildew. A forgotten load of laundry in the washing machine, the pile of clothes at the bottom of a closet, or even the armchair in a humid room can all quickly become overrun with mold. However as long as you catch the problem early, your fabrics can still be saved.

    Bleachable fabrics

    If you can apply bleach to a fabric without worrying about discoloration, do it. Thats the fastest and most effective way of getting rid of mold. Many laundry bleaches can be used on white and colorfast fabrics, although you should always check the instructions, and never use bleach on wool or silk. Simply apply a solution of one part bleach to three parts water and let it absorb into the fabric for a few minutes before laundering as usual.

    Non-bleachable fabrics

    For fabrics that cant be bleached, use white vinegar instead. Either apply white vinegar to a cotton pad and place it on top of the stain for five minutes before laundering, or briefly soak in a solution of ¼ cup vinegar to one gallon water. Rinse through to remove the vinegar and launder as normal.

    Get The Air Circulating

    If your bathroom has a window, leave it open or cracked as often as you can to allow air to circulate through the space. Youll also want to use an exhaust fan to keep air moving and your bathroom dry when you shower or bathe.

    Leave your ventilation fan on for at least 30 minutes after you shower or take a bath, too. If you dont have an exhaust fan in your restroom, consider getting one installed.

    Tips To Keep Mold From Growing

    Since mold prefers a dark, humid environment, opening your windows daily to circulate fresh air is an easy way to discourage mold growth. If someone in your family has allergies, do this very early in the morning or late in the afternoon times when pollen counts are at their lowest. If opening your windows isnt possible, at least open your curtains during daylight hours.

    Cleaning Mold From A Painted Wall With No Water Damage

    The first step in cleaning moldy walls or ceiling areas is to take the appropriate safety precautions.

    While mold may not affect everyone, some individuals can have adverse allergic reactions to even small amounts of mold exposure.

    Individuals like infants, elderly, persons with weak immune systems, and people with chronic respiratory problems.

    If you plan to clean molds, even small amounts found in your home, take the right safety precautions. Make sure you wear gloves, N95 mask, and eye protection.

    After you fix the moisture problem, do a visual inspection to see how much of the wall is affected.

    Things You Will Need:

    • Dry cloth

    This cleaning method is for removing molds from walls and ceiling areas affected by surface growth only.

    Not for areas where drywall and components are damaged by mold and moisture.
