October 25, 2017


When I walk past products with a video running to advertise the darn thing, I usually just walk past it since a lot of it seems to be pure hype. At first, I thought the same thing here.
Well, we had 2 out buildings- one of which hadn't been cleaned in over 15 years and if you know about Florida dirt, grime, mildew and mold, you know that it can be near impossible to actually get clean. So I thought that if anything could help clean it, I would give this a decent try. Honestly, I didn't expect much but perhaps a little would come off, but the rest was going to be impossible.
So, I mixed it as indicated in my pump sprayer and proceeded to spray down the older building. Inside of a few seconds, you could actually see the crud dissolving and running off. Now, I pretty much knew that this was also going to need a little help with some of the lichen growing, so I did have the pressure washer hooked up and started working on it with that too. inside of a few minutes, the entire building revealed the true color underneath that was hidden by the crud.
Now, could it have been this clean without the pressure washer? Probably not in this extreme case, BUT I do believe that the cleaner made the entire job a ton easier and no doubt was responsible for cutting off so much of the old, hard, nasty crud. AND I also tested it on some concrete that had a ton of mildew and moss around the hot tub without the pressure washer. Now that was an easy clean as I let it sit for about 3-4 minutes and a simple hose off was all it took.
If you want something that actually works as the "video advertising" says, then take my word that this is as good as it claims.

Wooden Fence after 30 SECONDS Outdoor CleanerTwo years ago I bought a condo that has a wooden fence around the patio. I have no idea when the previous owner last cleaned and stained the fence, but it was time to be done. I read about this 30 Seconds Outdoor Cleaner when researching products to clean wooden fences before they are stained. I bought a tank sprayer to apply and followed all the directions. The photos will tell the story - excellent product! I did use a toothbrush in tight places to scrub off the mold/mildew, but otherwise it was easy to use. Now to wait for another nice weekend and apply the stain.

I am nearly 70 yrs old and scrubbing is out of the question for my aching bones. I sprayed it on my gutters that had black and green areas, on my painted deck, concrete patio and aluminum siding. I only had a few areas that I had to re apply and let set for about 5 minutes. I rinsed it off with a water hose. I could not believe how well this stuff works. I also read reviews about the odor of bleach. There is hint of bleach, but nothing like the smell you get from straight bleach. I will be using this from now on.

My white soffets were black with mold and dirt...a friend of mine said he tried this and was pleased. I used a tank sprayer at 50/50 mix...sprayed it on the soffet...waited about 45 seconds and sprayed the hose!!!...gotta tell ya...i was amazed,and very impressed. I did it a second time due it being really badly dirty. They are now like new. This product for once actully does what it says....oh and by the way...it does smell..and you will get it sprayed on you but its worth the trouble. Its also plant friendly.

My wife found this on a pop-up camper forum for cleaning canvas and thought I should try on the deck. The dirt/mold DISAPPEARED on the deck in less than 30 seconds. I previously had scrubbed with straight bleach in desperation with only marginal results. We used it on canvas too. Great product. NO scrubbing required. Spray, blink your eyes, and wash off. This does contain TSP, so it will dull paint finishes some (perfect for prep of new coat of finish/paint). Picture shows (foreground) scrubbed with bleach, (center) untouched, (distant) 1 minute after applying this product. Wow! Second picture - finished result after rinsing.

When we installed our redwood deck, we treated it with water seal however after 3-4 years with no subsequent re-treatment, the timber had greyed so we set about refinishing the deck a couple of weeks ago. The first stage involved pressure washing the grey colored deck with water. After this was dry, we then cleaned the deck with 30 Second Concentrate which brightened the wood and helped lift out some of the old water seal. We decided to go with the 30 Second Concentrate after reading the reviews on Home Depot's website and we weren't disappointed. We diluted the 30 SECONDS® Concentrate 50:50 with water and sprayed it on with our deck sprayer and scrubbed it with a long handled nylon kitchen/bathroom brush before rinsing it off with water from the pressure washer. Working in the sun, we worked down the length of the deck planks, treating an area about 24" long and 4-5 deck planks wide at a time. Anymore and the concentrate will soak into the deck planks and you'll spend more time re-spraying the planks to keep them wet as you scrub them. One gallon of concentrate treats about 200 square feet once it is diluted, so we ended up using 1.5 gallons for our 322 square feet deck. The results of the 30 Second Concentrate was a brightening of the deck wood from its pressure washed finish, although it was nowhere near as much of a difference from the first treatment of pressure washing the grey deck wood I was glad we did it as I feel we got the deck wood as clean as we could before re-sealing it. Once this had dried, we applied a coat of Honey Gold tinted water seal using a pump deck sprayer and a 3" chip brush. We applied the water seal working down the deck again along the full length of the planks just as we did with the 30 Second Concentrate cleaner. Our deck used less than a gallon of water seal with the spray and brush method and we were very pleased with the results as it has left our deck looking good as new as can be seen from the before and after pictures. All in all, about a weekend's work.

Excellent product. We usually pressure wash our stone patio...what a mess. We have tried mixing the bleach with tsp. with so-so results. 30 second cleaner works for us. Mind you, our stone gets very moldy because of the many shade trees. We just use a bucket and scrub brush. WOW what a difference

I used the 30 Seconds cleaner for the first time ever on the north side of my house. It' was quiet mossy. The cleaner was so easy to use and rinsed right off with my garden hose. The vinyl siding looks like new. I can't believe how fast it worked and how little I had to do. All these years I've been scrubbing the siding by hand. Going back to The Home Depot today to buy 4 more gallons to do the rest of the house. I would defiantly recommend this product. WOW!!!

Home Depot came thru on this product. I was unable to get this product from other sources even though it was shown in their catalogs. Used 30 Seconds cleaner to remove moss from the roof of my utility shed. Tried it on my deck and now I have to finish the job. Made more work for myself. Really cleaned off the mildew on the deck and restored the color to the deck flooring (composite material). I will use this product in the future. I give it 5 stars.

I used this cleaner to get the green and black stuff off my deck, railings and glass and it worked excellant and it takes very little effort. I also used it to clean algae etc. off my concrete sidewalk and it also worked excellant. I am going to buy some more! Highly Recommended due to price, ease of use but mostly because it works

This stuff lives up to its name. I sprayed it on and then started scrubbing with a brush. DON'T do that. Just spray and let it do its job. It didn't need my help. In a few places I wiped with a rag, but overall, it did 90% of the work. It cleaned two outside resin chaises that had been sitting behind my shed for 3 years. The dirt had seeped into the resin. I thought I would have to throw them out and buy new ones. This stuff made them look like new and I have saved about $200+

Hi Bob
Yes, 30 SECONDS Outdoor Cleaner will certainly clean stains from algae, mold and mildew off your boat covers. Since we have been manufacturing 30 SECONDS for over 35 years, I have a few pointers I’d like to share.
Usually this type of item is made to be durable outdoors but I still recommend trying 30 SECONDS on a small inconspicuous area first, to ensure that it is colorfast. If the color doesn’t fade within the first 15 minutes, then you are good to go.
Don’t clean the cover over the water. You shouldn’t rinse 30 SECONDS off and have it run directly into the waterways. The best place to wash the cover is in the grass. When you rinse off 30 SECONDS it will run into the soil and breakdown, and not harm the grass.
The last piece of advice is that when you are rinsing make sure you rinse really well. Pay special attention to the stitching area. The cleaner has a tendency to pool in the grooves of the stitching. You don’t want it to sit there over time and rot. The best way to avoid this is to rinse, rinse, rinse.
You are now set for success. And if you choose to proceed, you are going to see how easy 30 SECONDS is to use.

I would like to use 30 sec cleaner to clear up the scum on the heavy glass in my shower. Can I?

Hi Ed
30 SECONDS Outdoor Cleaner is designed to tackle algae, mold and mildew on just about everything outdoors. I know its tempting because it works so easily but I don’t think the scum on your shower is a very good candidate for 30 SECONDS. Bummer.

I have a white concrete tile roof that was new 15 years ago. It was permanently impregnanted white so no painting required. It has only been cleaned once and that was by a professional company that charged an arm and a leg for 30 minutes of their work. I used this product after reading reviews of how good it was for everything but nothing about roof cleaning. Well I tried it this morning. I have a siphon on my hose and jet stream fitting on the hose. I sprayed it all over the roof and while it took close to an hour to empty the gallon bottle of cleaner, I could see results on areas that had it applied and it was amazing. The Florida sun and heat dried it quickly but I know when the next rain comes it will be white as snow again… Thanks for a great product….

Can 30 Seconds cleaner be used to clean the exterior of a motor home?


October 03, 2016

That is a great question about using our Outdoor Cleaner to clean your motor home. We actually have some really impressive before and after pictures on our Facebook page from a customer who recently used 30 SECONDS to clean their RV and were blown away by the results.
30 SECONDS is safe to use on painted metal surfaces, such as your motor home, without concern of etching or damaging the finish. I would like to offer one piece of advice. Make sure that you rinse very well around windows, doors, and the rubber seals that keep these areas water tight to prevent left over cleaner from drying on it. You don’t want it to sit on the seals long term and possibly degrading them. The cleaner won’t harm the windows at all, it can just be difficult to clean dried product off of them.
Be sure to take your own before and after pictures to post on our Facebook, too!

Good Question Tony,

30 SECONDS is intended as an outdoor cleaner and we haven’t done any testing using it in a washing machine. I’d rather play it safe than sorry and encourage you to look for a different product to clean your washing machine.

Thank’s for the question. Cheers!

Hello. I was a faithful user of 30 second cleaner for years on my old house which had white vinyl siding. The siding looked new for the new owners with just one application (no scrub just double spray and rinse) that I performed annually. My new construction house has a black metal standing seam roof which also needs to be maintained annually. Can I use 30 second cleaner? Thanks!

Jessica Merly

July 19, 2017

Hello Linda, Of course it is always best to test first, but 30 SECONDS Cleaners should perform beautifully on your black metal standing seam roof. We would love to see before and after pictures, just email them to info@30secondscleaners.com or tag us on Facebook, 30 SECONDS Cleaners- USA. Cheers!

Can I use this product on my RV rubber roof safely?

Jessica Merly

September 18, 2017

Hello Terry,
We always recommend testing our 30 SECONDS Outdoor Cleaner first when using on a new surface. That being said, we did have a customer share some amazing before and after pictures on their RV roof and awnings on Facebook! So in short, test first, but most likely you, too, will feel the ‘WooHoo!’ effect!

I have black mold on a sandstone retaining wall … a soft stone. Any problem?

Jessica Merly

January 04, 2018

Hello John,
30 SECONDS Outdoor Cleaner is made to be safe on most all outdoor surfaces including natural stone. However, when cleaning a new surface, it is a good idea to test first for results. Simply apply a couple drops, let sit for about 5 minutes, and then rinse. Thank you for asking. Cheers!
