    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.

Wear rubber gloves and avoid unnecessary dripping into your garden or grass.

    Follow the directions on the container of the cleaning product, making sure that the previous cleaning solvents have been thoroughly rinsed off with a strong blast from the hose. While the product used may claim that scrubbing isn’t necessary, it will probably be necessary to have those sleeves rolled up continue to scrub the moldy/mossy area until it’s free of all the green stuff.

    How To Clean A Concrete Driveway With A Hose Or Pressure Washer

    Here’s what you’ll need for cleaning everyday dirt and grime from a concrete driveway:

    • A garden hose with a spray nozzle
    • A concrete driveway cleaner
    • A stiff broom to scrub the driveway

    To remove stubborn dirt and stains, a pressure washer is often more effective, but you need to know what youre doing. A power washer blasts water at anywhere from 1500 to 3300 psi, more than 50 times the force of a typical garden hose with a sprayer. If you use a setting that is too high or range that is too close, you could actually etch the concrete. See these tips for power washing concrete.

    Tip: If you only plan to use a pressure washer once or twice a year, renting one may be cheaper than buying one. And you wont need to worry about storing or maintaining it. If you’ve never used a pressure washer, you may want to hire a professional who knows exactly how to clean concrete driveway surfaces without doing damage.

    Removing Stains With Cat Litter

    Cat litter is a product that naturally absorbs moisture. It is an excellent tool to remove moisture that has seeped down into the pores of the concrete.

    Kitty Litter Oil Stain Remover

    • Biodegradable cat litter
    • Water

    For stains that are new and still damp, like grease stains on concrete, cover them with a thick layer of kitty litter and let it sit for at an hour. The litter works as a natural absorbent and soaks up the fluid. Use a broom to sweep away the cat litter.

    If the stain has dried, cover it with a thick layer of kitty litter for an hour. Wet the litter with water. Use a bristle brush or another stiff brush to begin scrubbing at the stain. Rinse away the litter and let the spot air dry. Repeat as many times as necessary.

    Start With The Densely Populated Spots

    As mentioned earlier, the densely populated spots are harder to clean. Youll need to spray the proper amount and let it soak.

    The thick spots should be left to soak for at least 15-minutes. The soaking will follow with cleaning and rubbing out the grime.

    What about other areas?

    The regular infection deserves nothing more than 10-minutes. It means you can start rubbing off the less rough streaks in around ten minutes of time.

    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.
