Battling Algae, Mold and Mildew in Florida

Algae, Mold and Mildew Growth in Florida

Florida has more than its fair share of the humid, wet weather that results in stains from algae, mold and mildew. Recent years have even seen an increase of slimy orange, green, and black growth, or blooms. In fact, it's been so bad that 2013 was called the Toxic Summer from all the thick algae in the ocean coating the beaches and harmful algae blooms choking up waterways. As a homeowner, or a diligent renter, this means even more unsightly stains and slippery black surfaces around our homes.

Customer Review

"My husband and I bought 30 Seconds Cleaner at Home Depot for the first time today.  I was skeptical.  We have tried many products to clean our white PVC fence, but we always end up having to drag out the pressure washer and scrub.  Every time we do this, about every six months, we end up spending an additional $50 in water during that month.  My husband went outside to test it, and I waited, not expecting much.  Not long after he went out, he came back into the house insisting I come out to take a look.  I still did not believe him.  I was AMAZED at the results!  In the short time he had been outside, he had cleaned several large sections of fence.  It looked like new!  Then he showed me how easy it was.  He sprayed another section, and right before my eyes, the green mold and slime seemed to melt away.  It was a miracle!  I have never been so pleased with a new product.  So much so, I had to share the results with you, and take the time to thank you for creating this product.  I will never have to pressure wash the fence again.  This will save us time, and some back breaking work.  I have attached  a before and after picture, as well as a video link.  Please feel free to use it to show the effectiveness of your product."

Is your product safe to use on the screens we have in Florida around our pools?

Jessica Merly

June 30, 2017

Great Questions, Jamie! Yes, 30 SECONDS is safe to use on the screens and lanais surrounding pool areas. We always recommend you test first when cleaning a new surface. Apply the cleaner, wait 5 minutes, and rinse to see what results to expect. Make sure you rinse well if there is any exposed metal. Feel free to reach out to us directly if you have more questions, 503-669-1953. Cheers!

We own a rental property which had a plumbing leak (Small leak, but went undetected for about a year).A plumbing company repaired the leak, but warned that the ceramic tile wall would need to be removed in order to remove/take out the black mold. Do you have a product which could be administered through the top of the wall ABOVE the mold where the wall is sheetrock (gypsum board), so as to not disturb the ceramic tile. Thank you. Don Weso

Thank you for your question, Dan. Our products are outdoor cleaners and are not the best options for treating black mold in walls. We would recommend you try and talk to a contractor who specializes in properly removing black mold. Good luck with your project.

Is 30 Seconds Outdoor Cleaner harmful to fish and wildlife? I live on the water.

Jessica Merly

October 19, 2017

We are glad you asked, Harriet!
30 SECONDS Cleaner breaks down readily in the soil. However, it should be kept out of waterways. If you have to rinse into the water, then we wouldn’t recommend using our product. Thank you for double checking.

Do you recommend your product on travertine pavers on a lanai around a pool?

Jessica Merly

November 13, 2017

Hello Anthony,
30 SECONDS Outdoor Cleaner is made to be safe on most all outdoor surfaces, including travertine pavers. However, we always suggest testing in a small, inconspicuous area first when using it on a new surface. Simply apply a few drops, let sit about 5 minutes, and rinse to see results.
For the pool, rinse as much of the product away from the pool as you can and double check pH levels before swimming.
Thank you for your question.

I have a newly painted picket fence all different colors will this remove the paint as the bleach did🙁

Jessica Merly

June 18, 2018

Hello Janet,
We do strongly recommend testing when cleaning a new surface for the first time, especially if a surface is susceptible to dulling or bleaching effects. Red and purple paints can be particularly finicky, and you should test any cleaner that you use on those colors every time you clean. You’re welcome to give us a call if you’d like to discuss your project, 503-669-1953. Cheers!

I have a pavered walkway. Is this safe to use on pavers and will it hurt the plants along the walkway?

Natasha

Hello, does your product contain bleach? Can it be used on travertine deck tiles?
Thank you.

Jessica Merly

July 24, 2018

Hi Kay,

We do recommend testing 30 SECONDS Outdoor Cleaner when cleaning a new surface for the first time. Depending on the age and type of stone, efflorescence can occur with many types of cleaners, so testing is always best.
30 SECONDS Outdoor Cleaner is safe to use around your lawn and landscaping, so the plants around your pavers will be just fine. If you spray directly on to the foliage, just give it a quick rinse within 10 minutes to prevent sun spots. Happy Cleaning!

Hello Natasha,
30 SECONDS Outdoor Cleaner does not contain regular household bleach. Our Outdoor Cleaner is our proprietary Industrial Sodium Hypochlorite which works in conjunction with the powdered soaps that let our product get deep into the surface to root out and remove the stains from Algae, Mold and Mildew.
We do always recommend testing a small section when cleaning a new surface for the first time, including your travertine tiles. Apply a few drops to an inconspicuous area, let sit about 5 minutes, and rinse to see results.

Can the 30 second cleaner be use to remove mildew from painted aluminum panels inside of a sunroom? Does it harm aluminum? Thanks.

We had a new pool/lanai enclosure installed after Hurricane Irma. Because of construction delays, the structure was spread out around our yard for about six weeks prior to being installed. Our irrigation system runs off a well, and the well water left white stains all over the bronze (painted aluminum) cage. I have no idea whether it’s from calcium or other deposits, but I haven’t found an easy way to remove the spots and stains. Would you’re product be effective on SW Florida well water stains? I do not believe they are rust related. Thanks for any input or suggestions.

Jessica Merly

September 04, 2018

Hello Matt,
Thank you for considering 30 SECONDS Outdoor Cleaner. Our cleaner is made to work against organic stains, such as those from Algae, Mold and Mildew or Dirt and Grime. Unfortunately it will not get you the results you’re wanting against hard water stains or mineral deposits. Also, you may want to be careful which product you chose as bronze can be sensitive to some types of cleaners. We would recommend you contact a trusted contractor or home renovation specialist to see what products they have tested and recommended for your cleaning project.
Sorry we couldn’t be of further assistance. Best of luck with your project.

Good morning, Jessica. Which product would you recommend for (1) cleaning a shingle roof (low pitch that I can walk on) and (2) a brick paver driveway? I’m wondering whether to use the 30 Second Outdoor Cleaner or Spray and Walk Away product. I’d like quick results but, at the same time, I’d like a long-lasting sealant to keep the mold/mildew away. Thx.

Jessica Merly

September 05, 2018

Hello David,
30 SECONDS Outdoor Cleaner can be used safely and effectively on both shingle roofs as well as driveways. This is an instant clean, but once rinsed away its work is done.
Many of our fans love to apply the Spray & Walk Away a day or so later. This way they get the instant clean of the Outdoor Cleaner, and the overtime treatment of the Spray & Walk Away. Depending on the growth in your area, consider re-treating with Spray & Walk Away annually to prevent the return of Lichen, Moss, Mold and Algae.
We hope that helps. Feel free to contact us for further questions. You can reply here or call 503-669-1953. Cheers!

Does 20 SECONDS Outdoor Cleaner get rid of the blackened concrete sidewalks (presumably from acid rain??)? Can it be used on tiny black spots on a texturized indoor bathroom ceiling? Can it clean lichen off a brick outdoor windowsill? Thanks!

Jessica Merly

September 18, 2018

Hello Jane,
Great questions! 30 SECONDS Outdoor Cleaner will help clean stains from Algae, Mold and Mildew from your outdoor surfaces. Acid rain stains require a cleaner that will work on mineral build up.
We do only recommend out cleaner for Outdoor use.
For Lichen, we would recommend our Spray & Walk Away. Click on Products on the top of the screen to learn more.
Cheers!
