Solving The Mildew Problem

With all this in mind, it makes sense that you should avoid bleach when tackling your mildew. So how can you successfully remove mildew stains without reaching for the bleach? Follow our simple tips below:

Make a Water and Vinegar Solution

A homemade water and vinegar solution is one of the most effective ways of creating an inhospitable environment for mildew spores and removing mildew from concrete.

Heres our step-by-step guide on how to do it:

Make sure you wear rubber gloves to protect yourself from the mildew spores and to prevent the acidity of the vinegar from irritating your skin.

Pour 9 parts water and 1 part distilled white vinegar into a spray bottle and stir the liquid to ensure the vinegar is properly distributed throughout the water.

Spray the mixed solution onto the areas of mildew and gently scrub the surface with a sponge to eradicate the black layer of the mildew. Wipe the mildew away with a clean paper towel.

Dip a clean sponge in undiluted white vinegar and wipe the mildew infested area. Make sure you apply enough vinegar to fully saturate the surface.

For minor mildew problems, leave the vinegar to dry for 15 minutes. If the mildew issue is more severe, leave the vinegar for at least one hour.

Pat down the surface with a paper towel until it is dry.

Continue with this method once a week until the problem has completely subsided.

If you have greenish-black stuff on your concrete patio, itâs probably mold, mildew, or moss. Damp or moist conditions from rain or humidity can encourage mold and mildew to grow in those nooks and cracks of concrete pavers or bricks. Itâs important to find a sure way to remove it that wonât destroy nearby landscaping and harm the environment with a blast of harsh chemicals. This method uses natural, super-versatile ingredients in most homes, such as vinegar and Borax. These cleaners should be able to tackle most cases of mold or mildew.

Use A Pressure Washer

If you have a small amount of mold or algae, you may find that the first two steps of drying out and sweeping the area is enough to remove it. If this is not the case, pressure washing is often quite effective in removing mold and algae from pavers, bricks or concrete.

If you do not have a pressure washer, you can purchase one relatively inexpensively to have on hand for this and future projects. You can also rent one or hire someone to power wash your surfaces for you. If you are pressure washing paving stone patios, walkways or driveways, you may need to replenish the joint sand between the pavers after cleaning them. This is typically included in a professional clean and seal paver service.

Pressure washing is often all you need to remove mold or algae from hardscapes, but if this does not work, there are other options.

Remove Mold From Drywall/painted Walls

Mold can often grow on drywall and painted interior walls, especially in areas where moisture and humidity are a factor, such as kitchens and bathrooms. Walls can also be affected if your roof or exterior walls are infiltrated by water. If the drywall remains wet, mold can begin to grow and penetrate the drywall throughout. When this happens, the drywall must be removed and replaced, as you will not be able to get rid of all mold under these circumstances.

Mold and mildew removal from basement and exterior concrete surfaces

The good news is removing black mold on concrete surfaces is fairly easy and straightforward. The main difficulty in removing the mold is the potential health hazards.

Removing black mold is just like any other form, it just requires extra care. Its recommended that you start with the minimum protective gear, such as a mask and heavy-duty gloves. It also requires an N-95 respirator to protect you from spores and goggles. This gear is recommended by the EPA when cleaning mold and will protect you from any spores released into the air.

When mold is found in the interior of a home, its a much bigger deal because of the serious health hazards of black mold. For more extensive interior mold problems, it may be best to hire a professional mold mitigation service for removal.

If thats not in the budget or youve discovered the problem while its still relatively small, you can do it yourself.

Begin by protecting yourself. Because mold can affect the respiratory system, its best to use a high-quality respirator to block out mold spores. Also, use rubber gloves and goggles for eye protection.

Create either a bleach solution or a solution of detergent and water. The Environmental Protection Agency suggests the latter as detergent can better penetrate concretes porous surface than bleach.

For thorough cleaning, use trisodium phosphate, an industrial-grade detergent that will kill mold and remove grease and grime. Apply the cleaner with a brush and scrub thoroughly to remove the mold and engage the roots. Wipe clean.

Once clean, use a bleach or vinegar solution and allow the solution to dry on the wall or floor. This will serve as a preventative to keep the mold from returning.

First Identify The Source Of The Smell

The easiest way to mask a smell is to spray a deodorizer or light a candle. However, this doesnt address the problem. As soon as the candle goes out, the smell will return. Plus, while a regular homebuyer might ignore a smell masked by a candle, a home inspector will not. You will have to address the must eventually.

Instead of masking the smell, eliminate it. Determine where the water in your basement is coming from and why it is prevalent. This may take some detective work. Walk through your basement and note where the humidity feels higher and where the air feels clammy. Follow your nose to different areas.

If you arent sure about the source of the smell, hire a mold specialist to evaluate your basement. Even if your downstairs area isnt moldy, these professionals can identify why water is getting in and how to remove it.

Once you know the you can take steps to fix the moisture problems. This could be a simple process like resealing the windows and repairing a small leak. However, you may need to take steps to reinsulate your basement to block water and humid air from traveling inside.

If your concrete patio has recently fallen victim to mold, it is important to take steps to get rid of it. Mold growth is unsanitary and it destroys the look of an otherwise beautiful patio. Follow the few simple steps below to quickly get yours mold-free.

Step 1 â Clean First

You will need to give your patio a thorough cleaning before proceeding to remove the mold. Begin by using a vacuum cleaner to remove any caked-on dust deposits, making sure to use a mini vac or feather duster to remove any from crevices or difficult-to-reach areas. You can also use a wet/dry vac in lieu of a vacuum cleaner, as these devices typically work well with concrete surfaces.

Once the dust has been purged from your patio, produce a homemade cleaning solution of mild liquid soap and warm water. Apply it and allow it to set in for several minutes before you give the patio a vigorous scrubbing with a hard-bristled scrub brush. Should you encounter any exceptionally stubborn stains, try using a wire brush instead. Follow up the cleaning by using a garden hose to rinse away any remaining traces of your homemade solution.

Step 2 â Apply Your Bleach Solution

Step 3 â Apply Your Finishing Touches
