Use Vinegar Or Bleach

When you start to see a little mold or mildew on your shower curtain liner, you throw it in the washer with some bleach or vinegar, and it comes out clean and mold free. The same thing can happen for your hardscapes. Bleach should not be the first line of defense for folks who have plants or grass bordering the patio or walkway that has mold, but this is another option you can try if pressure washing does not work.

If you are going to try this approach to remove mold or algae, first try a mixture of white vinegar and water to spray down the area and kill the mold. Vinegar is a great way to get rid of weeds, so you do not have to worry about overspray getting on weeds, but you do need to make sure you do not spray vinegar on wanted plants and that the vinegar does not run off into a natural grass lawn or flower bed. After you have sprayed the vinegar solution on the area and allowed it to work its magic for a few minutes, you may need to use a deck brush or scrub brush to address stubborn areas.


You will then want to rinse the area well with water.

If you opt for a bleach solution to remove mold or algae, you will need to rinse the area after application. If the mold or algae has stained your hardscape, you may need to repeat this process a second or third time to remove the stain.

    Three Diy Solutions For Removing Green Deposits

    In addition to specially developed products, there are lots of DIY solutions for cleaning patio slabs on various blogs and websites. Note: these methods do not guarantee success:

    1. A high-pressure cleaner Especially during spring and summer, many people choose a high-pressure cleaner for cleaning paving slabs. Unfortunately, there are two major drawbacks. First of all, you will blow the grout out of the patio tiles which might cause the tiles to displace. Secondly, the high-pressure cleaner might damage the tiles so the structure of the tile becomes more porous, which will cause the algae and moss to penetrate deeper into the tile. And this will cost you even more time and energy the next time you have to clean the patio.

    2.Chlorine or white vinegarAn often used patio cleaning solution is chlorine or white vinegar. Chlorine is however harmful to plants etc., which makes it unsuitable for outdoor use. White vinegar is more natural than chlorine, but can be harmful to some plants too, especially to grass and herbs. Be careful when using white vinegar, because the acid can damage natural stone with a high lime content. This is not suitable for every patio, so we advise you test it out in an inconspicuous spot first.


    If it does not work the way you expected it to? Then try the HG products especially developed for cleaning concrete patios and removing green deposits.

    Black Mold On Concrete In Basement

    For black mold on concrete in a basement, start by ventilating the area well. Because youll be using bleach indoors, open a window and escape the fumes when possible. Create a cleaning solution thats one part bleach to four parts water and apply it to the concrete. Allow this solution to sit for fifteen minutes before using a wire scrub brush to clean the mold off the surface. Make sure you leave the area while the bleach is soaking to prevent breathing in fumes. Its important to wear protective gear during this process, including rubber gloves and a respirator. After youve scrubbed the area, soak up the cleaning solution and apply clean water. Scrub once more and remove all surface water. Allow the area to dry completely. If your basement area is relatively damp, use a fan to dry the floor quickly.

    Use A Pressure Washer To Get Rid Of Mold

    The hot water pressure washer is a super ideal method that you can use to get rid of and remove the stubborn mold. Once you remove the dirt and other debris, you will be required to blast mold using hot water. To do this, you will need a power washer.

    Hot water assists in killing fungi cells and other stubborn microorganisms. However, it is essential to be careful while using this method, especially in situations where other plants are present in the surrounding patio.


    Once you have splashed the hot water, you will realize that the stubborn and sticky mold has become soft. As such, you will then be able to scrub the mold using a deck brush.

    Besides, you can use a steam cleaner to kill the mold on hard surfaces.

    Finalize this by replenishing the patio joint that your powerful jet water may have displaced.

    Tips To Keep Your Patio Clean Longer

    For those who followed the instructions, scrubbed hard, and used the solution a few times without much luck, know that sometimes tougher measures are called for. A product like Wet & Forget should do the job. While the label says it is bleach-free, phosphate-free, non-acidic, and safe near plants and on all outdoor surfaces , do take caution when using this product. 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.


    Try revisiting the area in a week or two to keep on top of the mold and mildew. Persistence will pay offif you regularly do a light cleaning of the space, more thorough cleanings every few months won’t be necessary.

    Consider Using Bleach Or Vinegar Before Pressure Washing

    Some prep work before you start pressure washing can enhance the cleanliness of your targeted surface. Bleach and vinegar are well-known disinfectants that kill bacteria, fungi and viruses. You can use mixed solutions of either to remove mold and mildew and their spores.

    Dilute with water to the appropriate concentration, pour into a spray bottle or a hand pump. You can use the same hand pump that you use for weed killer solutions. Then apply to the surface.

    With bleach youll want to create a solution that has 1 part bleach and 3 parts water. If youre using vinegar try a solution that has 1 part vinegar and 1 part water.


    After applying the bleach or vinegar solution, let it sit for 5-10 minutes before continuing on to pressure washing for the dirty work of washing and rinsing. The pressure washer will do a better job of tackling the removal of accumulated dirt and grime.

    Be sure not to fill your pressure washer with either of these solutions. They will damage your pressure washer. Bleach is very corrosive on metals and pipings. Do the prep work by hand first, then wash and rinse with the pressure washer.

    How To Prevent Mold And Mildew From Growing On Your Patio

    Dear Tim: My wife and I have an outdoor patio with colored precast concrete paving blocks. It doesnt take long each year for black mold and mildew to start growing on it. We also have an issue with moss and algae growing on it. I have to power wash it at least once a year and wonder if theres a way to prevent the moss, mildew and mold from growing in the first place. Am I damaging my patio with the power washer? Why is it growing on the precast concrete pavers? This problem cant be that hard to solve. Loren P., Okatie, S.C.

    Loren: I used to have the same problem on two massive brick paver patios in the back of the last house I lived in. It was a mind-numbing job that took hours and hours of work to restore the patio to brand-new condition each spring. I hated doing that job.

    Lets talk about why the moss, mold and mildew grow in the first place. Many years ago I couldnt understand how it could grow on solid rock, precast concrete or brick, but now its crystal clear to me.

    Moss, mold and mildew need food to survive, just like you and I. The food sources are assorted, just as humans diets are. Dust, ultra-fine sugar aerosols from trees and bushes, tree sap, minerals, organic debris, etc., are all food sources for the unsightly things growing on your patio.

    How To Remove Mold From Travertine Pavers

  • Dip a nonmetallic scrubbing brush into the solution and use it to scrub the pavers
  • Repeat step 3 until you have removed most of the mold
  • Wash the area with water from the hose to remove the mold and water solution with mild soap or detergent
  • To remove any remaining mold, wet the area again with the water and mild soap or detergent solution. After that, sprinkle talcum powder over the stains. Allow the talc to absorb the solution and to sit on the pavers until it is dry
  • Sweep the area with the scrubbing brush, rinse the pavers with the garden hose again and leave the whole patio to air dry.

      A pressure washer might seem like one of those tools that you never really get quality use out of, but it can be a highly valuable tool.

      Whether you are using it to clean dirty siding, hose down toys for the kids that have been in storage, or spray down dirt that has dried onto the sidewalk, a pressure washer is highly useful.

      It can also be used to clean a backyard concrete patio in an effective way. Keeping your patio clean will make it more aesthetically pleasing, creating a great hangout space for you, your friends, and your family to enjoy.

      But a pressure washer is not something that all of us have available. They can be a bit pricey and you may not wind up using it enough to justify the costs.

      That leaves you wondering what to do in instances where you need something deeply cleaned but dont have a pressure washer to get the job done.

      Not only that, a pressure washer can actually do damage to your home if you dont have the skills to properly operate it. It can result in serious damage such as pitting lines or surface degradation if you leave the spray in the same place for too long.

      There can also be damage to the mortar that is in between the brick since the joint sand can be washed away.
