White growth on concrete is nearly always efflorescence, not mold growth. You can verify this by spraying a bit of water on the suspected growth. If its efflorescence, it will disappear as the crystals are dissolved by the water. If its mold, it will flatten, but remain visible.
I recommend removing the rubber mats for now. The impervious nature of the mats will prevent the concrete from releasing the moisture. After a week or so, put a couple of mats back down. Peel them back a few days later and look for signs of moisture on the underside of the rubber. If you see moisture, pull them off and allow the concrete more time to dry.

Can Vinegar Kill Mildew On Driveway
Vinegar may not be the best option you have as a mold-killing agent on concrete or driveways. You may want to avoid using vinegar on specific surfaces in your home because of its acidity.
You should not use vinegar on:
- Stone counters Some stone surfaces, such as marble and limestone, can be dulled and etched by vinegar.
- Natural wood floors Cleaning wood floors with vinegar can damage the protective coating, which is why many flooring manufacturers include warnings on their product labels.
- Electronic technology Anti-glare screens can be damaged, and vinegar might interfere with touch screens.
- Metals of several sorts Stainless steel, aluminum, and copper are all metals corroded by vinegar. Even on stainless steel, this practice is generally discouraged.
- Porcelain-like materials Using vinegar to remove mold from porous or absorbent surfaces is improbable. If you see mold growing on your ceiling tiles or carpet, its time to replace them immediately.
Why Is Cleaning Concrete Driveway Better Without A Pressure Washer
There are advantages and disadvantages of using a pressure washer. Washers are a good cleaner on stains on woods and concrete. Some pressure washers have a soap dispenser, and applying cleaner is quicker than spraying. But, washers have a high pressure that can also damage these surfaces. Every time you use the washer, it may break the concrete little by little or leave streaks on a concrete surface. Due to unfavorable circumstances that might happen to the concrete surface by the pressure washer, most of the individuals that have no experience of using the washer prefer to clean outdoors without it.

How To Clean Mildew Off Concrete Driveway

This is a tricky one. If its hard to the touch, its not mold. Its either mortar or efflorescence. The latter will dissolve in water. Typically its powdery, but Ive seen it form hard, crystal like deposits in some cases. The fact you found mold on the backside of the sheet rock points to an ongoing moisture intrusion. This would explain the efflorescence, which occur when moisture moves through masonry. I recommend testing the deposits by submersing them in water. Do not reinstall the sheet rock until youve dealt with the underlying moisture issue.

Its difficult to determine from the photo whether this is mold or efflorescence. An easy way to distinguish between the two is by flicking a bit of water on the surface. Efflorescence will dissolve in water, mold will just mat down a bit.
Either way, it likely indicates vapor emissions moving through the concrete. You can verify this by taping a piece of plastic to the concrete. Recheck this in a few days. If you find condensation on the backside of the plastic, you have a vapor emissions issue.
In a garage this is not a problem, as long as you keep sensitive items off the floor. The vapor will eventually evaporate from the surface. Do not install carpeting on any concrete showing signs of vapor emissions! This will lead to major mold problems.
General Concrete Driveway Maintenance Tips
- Reapply sealer as needed.Resealing your driveway every few years will restore its like-new appearance and make it less vulnerable to stains. After cleaning the concrete, let it dry at least 2 or 3 days before resealing so you dont trap in moisture. Learn more about concrete driveway sealers.
- Act fast.The sooner you remove leaves, oil and grease spills, and other contaminants from your concrete driveway, the easier it will be to remove any stains they leave behind. Concrete is porous and can absorb stains, especially if it hasnt been sealed. This will make them much harder to remove.
- Avoid using deicing chemicals.Using deicers on your concrete driveway in the winter can cause surface damage in the form of scaling and spalling by forcing the thawing and refreezing of moisture. Sealers for concrete driveways may also fail in areas where deicing salts are applied or that receive drip-off from parked cars. As an alternative, use sand for traction.
- Re-sand the joints in concrete paver driveways.Concrete paver driveways have similar cleaning and maintenance requirements as poured concrete driveways. But you may also need to refill the sand in the joints between pavers if it washes away. Use a polymer sand, which contains a special polymeric additive that binds and hardens the sand and helps to prevent erosion.

Youll want to focus on two items increasing the temperature and the air flow. Addressing these issues will lower the humidity and the mold growth/musty odor.
Purchase a relative humidity gauge and install it in the basement. Your goal is to keep the RH below 50%. Increase the heat as necessary to lower the RH until youve reached 50%.
The easiest way to increase the ventilation is to run a bathroom exhaust fan. If theres an existing fan in the basement, run it at least 12 hours per day in the winter months.
Its also important to verify whether the basement is suffering from vapor emissions through the concrete slab. This occurs when water vapor moves up through the slab and into the room above. If the basement is carpeted, the moisture can become trapped and lead to mold growth. See our page on basement mold for more info.

Beat Black Mould The Diy Way
If you have black mould outside your home, you know how unsightly it can look. Black mould grows on surfaces such as your driveway, path, porch and roof, and it turns any area it invades into an ugly, sooty-looking mess. This hardy growth stubbornly adheres to surfaces, and it can be a real struggle to clean. Its easy with Wet & Forget, all you have to do is spray on and leave it. The weather will slowly decompose the dead growth and over time the surface will become clean! No elbow grease necessary!
Unlike green algae, which prefers shady areas, black mould has a dark-coloured shell that protects it from even the brightest sunlight. This protection means that black mould is perfectly at home on your path, driveway or roof, where it can cause a general black or grey discoloration.
The same shell that protects black algae from the sun also makes it tough to get rid of. Using bleach usually requires scrubbing, which isn’t exactly an easy job. A pressure washer is hard to use, and getting rid of black mould with a pressure washer can take some time. Worse yet, both of these methods risk damaging the surface. Bleach can be corrosive, and kill your lawn with caustic run off, and a pressure washer can cause wear and tear on the surface. Neither bleach nor pressure washing does anything to prevent re-growth, which means that black mould can start forming almost from the moment you finish cleaning and trap you in a cycle of cleaning and re-cleaning.

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.

Get Your Solution Ready
There are three ways to get rid of mold:
The first and least damaging way is to use vinegar. Mix white vinegar and water to treat the affected area. This will also help you kill weeds, but wont harm the grass on your lawn or flower beds. Spray the vinegar mixture on the mold, and after a few minutes, you can start scrubbing.
The second and most common way of treating mold is with bleach. Fill a one-gallon bucket with warm water and 3/4 cup of liquid bleach. Make sure you ventilate the area where youre working. Then start scrubbing with the liquid bleach mixture.
The third way to treat mold is the most extreme. You can add trisodium phosphate to your bleach water. You should only add one-half cup to every two gallons of water and bleach. Trisodium phosphate will work on tougher mold. But because of the solutions strength, you should handle it with care.
While youre treating the mold, using whatever mixture you have, make sure to keep it as dry as possible. You can use a vacuum to suck away any extra water or sponge it up yourself.
