Does 30 SECONDS Outdoor Cleaner Contain Bleach?

30 SECONDS vs Bleach

30 SECONDS Outdoor Cleaner does not contain regular household bleach.  

This common misconception comes up from time to time, since 30 SECONDS is a Sodium Hypochlorite based product. People often think our outdoor cleaner will act like a regular household bleach. We have even had customers do trials for us, because they were so dubious (or suspicious?)

The picture to the left is an actual picture submitted by a customer who tested our product against household bleach.  The results are clear to see! 

Our formulation designed to:

  • deep clean
  • be safe to use around your lawns and landscaping
  • be easy to use

There is a reason why we have been so popular since 1977. It works. And you get instant gratification!

Hi Deb, good question about the lichen. 30 SECONDS Outdoor cleaner may help to remove some of it, but for the best results we recommend our outdoor treatment, Spray & Walk Away. This will actually kill the lichen and then use the weather to erode it over time. While it won’t get you instant results, it will have a better long term effect in treating and removing the lichen.

30 seconds cleaner did wonders on the boat. It’s clean and bright.

I have another question. Can 30 seconds cleaner be used to treat lichens (black spots) on sandstone?

Laura, Its always a good idea to test in a small, inconspicuous space first, but Yes! 30 SECONDS Outdoor Cleaner is made to be safe on asphalt shingles. Make sure that you heavily saturate the surface as those porous shingles can be difficult to fully clean. Cheers!

Hello Deb, Great question about your boat. 30 SECONDS Outdoor Cleaner is made to be safe on most all outdoor surfaces. We do encourage you to test it in a small, inconspicuous area first if it’s the first time to clean a new surface.
Also, please make sure that you’re washing the boat on land. While our cleaner breaks down readily in the soil, we do ask that you keep it out of waterways.
Thank you!

Linda, thanks for asking if you can use 30 SECONDS Outdoor Cleaner on your rubberized pool deck. Our Outdoor Cleaner is safe on just all outdoor surfaces, including most rubberized pool decks. Of course when using a new cleaner it’s always a good idea to do your due diligence. If possible, we recommend you contact the manufacturer of the deck and insure that its compatible with a Sodium Hypochlorite based product. If that information isn’t available to you, you can always test in a small area first. allow the cleaner to sit at least 5 minutes, wash away completely and let dry. If all looks well, you’re good to go on the rest of the deck. Cheers!

Great question, PJ! 30 SECONDS Outdoor Cleaner does deep clean to remove the spores of Algae, Mold and Mildew, giving you longer lasting results that surface cleaners alone.

That being said, if you’re looking to really preserve the results from you cleaning, consider applying a treatment such as our Spray & Walk Away. This overtime treatment kills Lichen, Moss, Mildew and Algae and helps prevent growth from returning. Find out more about that here Cheers!

After the product cleans will it leave any type of prevention to keep the quick return of the mildew?

Kris, we are not sure where you heard that 30 SECONDS would harm your plants, but you’re in luck! 30 SECONDS Outdoor Cleaner is safe around your plants. So much so, that it even says “Safe around your yard, plants and lawn” right on the front label. So feel free to clean both your house and your drive knowing that your landscaping is safe.

Hi Judy,

We would like a little more information to properly answer your question about using 30 SECONDS Outdoor Cleaner. In general, 30 SECONDS Cleaners breaks down readily in the soil, and so should be okay over a “leaching field.” However, if there is standing water involved in the septic field, then probably not. 30 SECONDS should be kept out of waterways and may upset the pH and/or microbes used for breaking down waist. If this doesn’t answer your question, I’d invite you to call us directly for a more accurate answer, 503-669-1953. Cheers!

Kevin, when in doubt it is always a good idea to test in a small, inconspicuous area, however you should be fine using 30 SECONDS Outdoor Cleaner on your travertine pavers.

Nathaniel, the main ingredient in 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 stone to root out and remove the stains of algae, mold, and mildew.

Hi Kellie, I understand your concern about using our product on your canvas flies on your camper. Our 30 SECONDS outdoor cleaners are made to be safe to use on most outdoor surfaces, including canvas. However, we always recommend to test a small inconspicuous area first to make sure that the surface you’re using the cleaner on is colorfast. We guarantee that the product works and that you will be totally happy with the way 30 SECONDS cleans. If you are nervous about your particular canvas then I would suggest contacting the manufacturer of your camper. Tell them that you want to use a bleach based cleaner. They are really a much more reliable source for your specific project.
If you do choose to use 30 SECONDS then the best thing to do is rinse, rinse, rinse in all the nooks and crannies, once you are done cleaning.

I am considering using on canvas flys on our campervan but concerned this product will damage it. Can you guarantee this will not be the case?

Yes, Lynne, this question often comes up. 30 SECONDS Outdoor Cleaner is a Sodium Hypochlorite based cleaner. However, our formula is much more industrial strength to deep clean all your stains from algae, mold and mildew.
We often have customers looking for bargains but quickly discover that 30 SECONDS is worth every penny.
We have many before and after pictures on our main web page that show customer comparisons – I encourage you to explore this and other info on our site.

I bought this to clean up the white pebbles and also the pavers around the pool. It sure smells like bleach, has the same viscosity as bleach and appears to do the same job as bleach, the only difference so far is that I could have actually bought bleach at an eighth of the cost. Sodium Hypochlorite – household bleach.

Carolyn, thanks for the question! You can see how much cleaner 30 SECONDS has cleaned this customer’s deck. It is formulated to do a deep clean. I think it’s great to be suspicious, which is why this particular customer, shown in our blog, decided to do his own trial. He too was doubtful. And now very happy.

So why is it different from household bleach? Clorox isn 6 % sodium hypochlorite, yours is 5%. What are the “inert ingredients”? is that what makes it more safe for pets etc.? please explain…. yes I am suspicious after reading the label so want to know how it is different.
