Mold and Mildew Removal Using Hydrogen Peroxide
Your medicine cabinet houses an inexpensive and hard hitting mold and mildew remover. Hydrogen peroxide is typically available as a 3 percent solution sold in pharmacies. 6 percent hydrogen peroxide is used in beauty salons, 30 percent hydrogen peroxide is found at medical supply stores for medical uses and some health food stores carry 35 to 50 percent grades. If you use greater than a 3 percent solution, wear gloves, eye protection and a respirator. Many homeowners have found hydrogen peroxide makes a perfect substitution for chlorine bleach. Some people cannot use chlorine bleach due to their sensitivity to chlorine and require an alternative that will be an effective mold and mildew killer.
Removing Shower Mold and Mildew
Mold and mildew thrive in a warm, damp environment making the shower or tub surround the perfect place to flourish. Mold and mildew typically attach to porous grout and caulked corners rather than the smooth face of tile or fiberglass where it cannot form a tight grip.
Mix equal amounts of water and 30 percent hydrogen peroxide in a spray bottle. Mix only enough that you will be able to use right away because the mixture loses its effectiveness when stored.
Liberally spray the mold and mildew on white or light colored grout or in corners and other areas where you have mold and mildew.
Let the mixture sit for 45 to 60 minutes.
Generously spray the mold and mildew a second time with the hydrogen peroxide and water mixture.
Dip an old toothbrush or other soft bristle brush into the mixture and scrub away the mold and mildew.
If mold and mildew stains remain, dip a cotton swab into undiluted hydrogen peroxide and dab at the stains. Let the hydrogen peroxide sit for 20 to 30 minutes. Wet the toothbrush or soft scrub brush with undiluted hydrogen peroxide and scrub the stains.
Do not use hydrogen peroxide on dark colored grout because the hydrogen peroxide will lighten the color.
As a side bonus, if you have white grout that looks dingy and dirty regardless of how much scrubbing you do, spray all the grout lines with the 50-50 mixture and let it sit and whiten the grout. Rinsing is not necessary.
Removing Mold and Mildew from Basement Walls
Typically large basement mold and mildew cover large areas and can be toxic if left to thrive. Whenever you are addressing mold and mildew in a basement or other area of the house, find the source of the water that is promoting the growth and the necessary action to correct the water problem or the mold and mildew will return. Take proper precautions including wearing rubber gloves, safety goggles and a mold and mildew filtering respirator.
Fill a spray bottle halfway with a 35 percent hydrogen peroxide solution and add water to fill the remainder of the bottle.
Generously spray the moldy areas. Do not scrub at this point because you will release live mold spores into the air where they will settle on other surfaces and grow.
Let the solution sit on the mold and mildew for 30 to 45 minutes and then spray again. Continue to spray the mold and mildew, wait 30 to 45 minutes until you’ve repeated the pattern at least six times.
After the final spraying, wet a rag with the solution and wipe the walls to remove mold and mildew stains. Spray the walls again if any stains remain.
Scrub the mold and mildew off the surface with a scrub brush.
Consider painting the basement walls with a mold and mildew inhibiting paint and primer.
