How To Get Rid Of Mold On Walls
Many people first notice theyve got a mold problem when they see it growing on their walls. Check in the corners near the ceiling and floors in rooms with high moisture levels, such as kitchens, bathrooms, laundry rooms, and basements.
Step 1: Make a solution of one part bleach to three parts water in the spray bottle.
Step 2: Saturate the mold and surrounding area on the wall.
Step 3: Let the solution soak into the mold for 10-15 minutes.
Step 4: Using the scrubbing brush, remove the mold and stains.
Step 5: Repeat as necessary to remove all the traces of mold and mildew.
Step 6: Make a 50/50 mixture of white vinegar and hydrogen peroxide in the second spray bottle.
Step 7: Spray the cleaned surface and allow it to absorb and air dry.
This method works because it addresses the visible mold, as well as the underlying roots that often go untreated. Surprisingly, vinegar and hydrogen peroxide are both more effective at killing mold roots than bleach. Because they work best on different types of mold, try to use them together to cover all the possible varieties of mold you might be dealing with.
Pro Tip: If you dont have hydrogen peroxide at hand, you can also clean mold with vinegar and baking soda instead.
Use Borax To Scrub Away The Mold
Borax has a higher pH than baking soda or vinegar, which makes it the best option for killing mold. Youll want to use 1 cup of Borax for every gallon of water you use.
Take a vacuum and remove as much freestanding mold as you can.
Then scrub the mold with your Borax solution until the signs of it disappear from the drywall. Wipe away any excess moisture and allow the drywall to then dry.
Dont rinse off the mixture.
Vinegar is an even safer option, but it only kills about 80% of household molds that may form.
It may be non-toxic, but it may also be ineffective.
If you do use vinegar or baking soda, make sure you leave your preferred cleaner on the mold for several minutes before scrubbing it away to achieve best results.
Youll then want to apply vinegar on the affected drywall every few days for a couple months to make sure no spores decide they want to grow.
