How to Get Rid of Mold on Bricks with Homemade Natural Cleaners
#1 Water (pressurized or abrasive blasting)
If you have ever heard the term “pressure washing” and always wondered what it is, to put it simply, it is high-pressure water spraying that blasts away at mold, dirt and grime.
It can be used in various different surfaces and objects such as concrete surfaces and building structures. Ultimately the amount of mechanical pressure of the washer is equal to the gallons inside the pump.
Pressure washing is extremely effective in removing mold from various surfaces. Pressure washing is also referred to as power washing.
Pressure washing refers to washing the surface using a special tool and consists of 2 to 4 high-pressure chips located on a rotating bar that assists this process. Ultimately, this creates a uniform cleaning pattern and cleans flat surfaces very quickly.
Lots of people use pressure washing to clean decking, sidewalks, patios, siding, roofs, gutters and brick surfaces as well.
If you’ve ever heard of people saying that they have removed mold using vinegar, there’s a good reason why.
Vinegar is a mild acid that kills approximately 82% and more of mold species. In some cases, baking soda is used in conjunction with the vinegar depending on the type of mold you are trying to eliminate.
However, white distilled vinegar on its own, watered down and placed in a spray bottle is effective on its own. The vinegar should be sprayed directly onto the moldy surface and allowed to sit for an hour.
Finally, you should wipe the area and allow it to dry. The smell of the vinegar should also clear within a few hours.
#3 Dish Soap (Dawn) & Salt
Although dish soap has been used to help get rid mold, it’s not very effective. Dish soap is a rather mild and gentle cleanser and therefore using this ingredient alone will not help you to eliminate mold.
Dish soap can, however, be added to the chlorine, bleach mixture or vinegar mixture in order to increase its effectiveness.
However, on its own it simply works as a mild cleanser and will not remove mold from any surface.
#4 Boric Acid
Boric acid is also very effective in eliminating mold. Warm water is excellent as it dissolves the boric acid quicker.
However, you should never ever use boiling water with this acid. In some cases, you can use hydrogen peroxide and added tit o the mixture; however, it is not compulsory.
When using the mixture, spray it onto the affected surfaces, leave it to sit for 2 minutes and then wipe the surfaces. Thereafter, ventilate the area well.
#5 Baking Soda
While baking soda is a mild multipurpose ingredient, it’s also a white mineral powder. This means it can be used to kill mold inside around your home and it is also safe to use around pets.
Aside from eliminating mold, this mixture will keep moisture at bay and help keep mold away.
In order to kill mold using baking soda, you need to add 1 quarter of a tablespoon baking soda to a spray bottle with water and shake until it is dissolves all the water and then spray the moldy area with the mixture.
Thereafter, allow it to sit for a few minutes using a scrub brush surface. Then rinse the surface with water and remove moldy residue from the surface. Spray the surface again and allow it to dry.
