Protecting Plants During Treatment
Since I am listing several chemical treatments to get rid of algae and/or mold and mildew, I feel it is important to stress the need for plant protection. Each option listed above will present its own unique potential for damaging your plants. You will need to judge which option is safest.
However, it is incredibly important that you always do a pre-soaking on your plants and/or lawn when using any chemicals. The water will help to protect leaves and to saturate the soil in an attempt to dilute any runoff.
It is also important that you be mindful of the direction of your water runoff and act accordingly. Focus most of your pre-soaking on areas that will receive the brunt of runoff.
Always use a controlled application container, such as this lawn treatment sprayer.* And always do your treatments on calm days. Any breeze can carry mists of chemicals to plants that you want to protect.

How To Remove Mold From Composite Decking
Care needs to be taken when using cleaning products with composite wood to avoid damaging the deck. Pressure washers should never be used on composite decking as the force of the water can easily imprint the plastic in the decking, ruining it.
Its also a bad idea to use bleach on decking. Most composite decking manufacturers warn that bleach will discolor their products, especially if used in sunlight. Chlorine bleach can also affect the composition of the decking, causing it to crack or chip prematurely.
Instead, use a mix of dishwashing liquid and water, which will remove the mold but is mild enough not to harm the deck. As with cleaning stained and painted decking, apply vinegar with a spray bottle after cleaning to prevent future mold growth.

How To Clean Anything Around A Pool

Ive been around pools all my life, and I think Ive cleaned everything there is around a pool. Todays post is not how to clean a pool, or how to skim and vacuum, today we talk about cleaning specific pool surfaces.
Few pools are located in spotless environments, without rain, birds, dust and other things that smudge and stain our pool surfaces.
So then, heres my tips on how to clean the various surfaces around a pool.
COVERS
Solid Winter Pool Covers and Solar Covers can be cleaned with dish soap, but residue left on the cover can transfer to the water. I suggest using the all-around Tile & Vinyl cleaner, in small amounts, with heavy scrubbing with a stiff brush or broom. But more important than what you clean it with, is where you clean the cover. A clean, sloping surface is best. Clean a 5-10 section, fold the cover over the cleaned area, and repeat.
Automatic cover stains are often hard to remove completely, but can be removed with a natural cleaner like Orb 3 Enzyme Cleaner, or Simple Green. Small amounts of automotive buffing compound can be rubbed into the surface, and buffed clean to remove stubborn stains or watermarks. Applying vinyl conditioner to the auto cover material also helps to resist stains and make it easier to keep it clean. Never use any harsh acids or chlorine-based cleaners on auto cover fabrics.

What Is Green Algae
And how do you tell it apart from moss, mold, and mildew?
Algae is a slimy, green film that grows on wood in wet, dark conditions. Moss is also green and grows in similar conditions, but is soft and fuzzy to the touch. Mold is a fungus that appears on wood as greenish-black streaks. Untreated, mold spores can pose a health risk to people and pets when inhaled.
While algae, moss, and mold are different, they are all equally harmful to your deck and should be treated right away.
Can Black Mold Damage My Deck
Black mold isnt just unsightly. If left unchecked, it can and will eventually destroy a deck as black mold is usually accompanied by wood-eating fungus.
Mold breaks down the wood fiber, leading to rot and decay. Rot will ultimately impact the structural integrity of the deck, requiring parts of the deck to be replaced.

Does vinegar kill algae?
Vinegar is a non-toxic solution for killing algae.A mixture of three parts water and one part vinegar can be sprayed on the algae, resulting in removal of the unsightly green growth while leaving nearby soil safe for other plants. Chlorine is often used to kill algae, but applying it to some materials can bleach them.
How To Get Rid Of Mold Under A Deck
Black mold that forms on the underside can be unsightly, especially if you have a two-tiered deck and youre forced to look at it every time you use the lower section.
Removing this mold can be a real challenge, requiring ladders and difficult above-the-head work.
A pressure washer is the most effective way of cleaning the underside of a deck however, it can be tricky as using too much pressure will damage the wood.
Another option is to use a garden sprayer with a cleaning solution. A solution with oxygen bleach, which unlike chlorine bleach, wont harm plants, is effective at cleaning away mold.
Apply the solution, use a scrub brush on the end of the pole to remove the mold, then use a standard garden hose to rinse.
Keep in mind that cleaning the underside of a deck presents additional hazards. Working from a ladder presents the danger of falling, and cleaning the underside of the deck means water and cleaning agents will be dripping onto you as you work.
With that in mind, be sure to use protective goggles and clothing when cleaning the underside of a deck, as you will get wet.

How To Clean Mold From Concrete
The best solution is to scrub and clean the affected areas with a mold-killing detergent, like RMR-86 Instant Mold & Mildew Stain Remover, or a simple solution of household bleach and water. Be sure to scrub aggressively to get down into the pores of the concrete. Let the detergent or bleach solution soak in for a while to ensure that all the mold is killed. After scrubbing, rinse with a power washer to get all the solid organic matter out of the concrete.
Once you’ve tackled the mold you can add color or an overlay to completely transform your concrete!

What Is The Difference Between Mold Moss And Algae
Mold and mildew are fungi that live off of dead organic matter. They grow and spread by decomposing things like fallen pine needles, leaves, twigs, or even the fibers of your wood deck boards.
Mold is the more dangerous of the two. Mold is typically slimy, fuzzy, and raised off your deck surface. Mildew lives on surfaces and lays flat – most often, its dry and powdery.
Moss and Algae, meanwhile, are plants that live off of sunlight and water. They dont decompose your wood deck boards like fungi do, but over time, they can still cause damage to wooden deck boards and rails.
Mold, mildew, moss and algae are all unsightly additions to your decks appearance. Fortunately, you can treat and remove them all yourself, typically by mixing up a homemade deck cleaner and scrubbing. Well run through cleaning methods for each below, then give you some preventative measures to stop deck growths before they start.

Is Green Mold Harmful
Contrary to popular belief, black mold is not the only type of mold that is harmful. Green mold has dangerous effects on humans who have been contaminated or accidentally ingesting it. They release airborne spores that can cause allergies, asthma, and other related respiratory concerns.
It is not safe to leave mold growths unaddressed, especially if they are located near your home. They have toxins that can even lead to blood poisoning and brain infections. Although it may not necessarily kill you, it can still seriously affect you and your familys well-being.
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.

How To Clean Artillery Fungus And Sooty Mold Off Vinyl Deck Membranes
Any permanent outdoor surface needs to be cleaned from time to time, and your vinyl deck is no exception. While the benefits of having a vinyl deck include no sanding, staining or re-coating of any kind, your deck will look its best with a seasonal cleaning . Sometimes, however, there are contributing factors in your environment that may cause you to require more than a general cleaning on your decks surface.
One of these factors is mold and fungi which in some areas under certain conditions can be a troublesome maintenance issue like that experienced by some homeowners in Florida experiencing green and black growth on their metal roofs.
The bottom line is that it is difficult, if not impossible, to control all of the factors that contribute to mold growth and your best defense to keep your vinyl deck clear of fungus and mold is a general cleaning 4 times a year.
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.
