30 SECONDS Cleaners Outdoor Cleaner, 64oz Hose End Attachment, Clear

Product was easy to use. Hook up product to hose, set to clean, hose down the side of house to be cleaned, set to rinse, rinse off product. Product took away a low of the algae/greeness out of our white aluminum siding quite well. I only applied this product to 1 side of the house and used the whole bottle. It would maybe be enough for 2 sides of a normal 2 story house. I was extra aggressive as it algae was quite noticeable on the siding. It smells of bleach and after looking at the active ingredient, it is mostly bleach. I don't particular care, but to some they might. It took care of a lot of what I was hoping it would. Siding looks more clean. It probably could ahve benefited from being scrubbed, but I do not have a long enough brush or an extension ladder to reach where I would need too. Again, spent about 10-15 minutes total to give a huge improvement on curb appeal for $14 and not having to scrub or power wash the siding.

I was tired of dragging my pressure washer out to clean the concrete around my place, so I tried this. It actually does a decent job. Leave it on for 15 minutes and rinse off. There was only one small area that I had to respray to get the mold off. I consider this a lot less time consuming than using a pressure washer.

This stuff just like the name works in second/ minutes. The bottle works well for spraying high to reach places. Max that the bottle can reach is about 2 storys. Once you have the bottle you and run out… I would buy pool shock and dilute it down. Works very well but all it is high potency bleach water.

I couldn’t wait to try this stuff I had green algae and dirt around my front door and bay windows and my 2nd story too. I mixed the Gslf water had solution I. Just a spray bottle to try around my door. It was amazing to watch. It made my white Audi g white again. I will hook it to a house and do my whole house

Recommended product. I've used this about 3 years ago and it works. The algae came back again and has been subsequently been removed.This product removes mold, algae, grime and dirt stains from house siding, decks and fences. Just attach your garden hose and spray liberaly. Attachment has Off, Clean, and Rinse settings. Safe when used as directed around your yard, plants and lawn.

I bought this product with hopes of cleaning off a large amount of black mold that was accumulating on my stained cedar deck. I had an oil based stain on the deck that I had applied last year. 30 second outdoor cleaner did a great job taking off the mold on my deck. It was very easy to do and quick. I was excited about the initial result. I tried this cleaner a second time and began to notice that the product was actually fading away my stain and effecting the waterproofing qualities of the stain. No longer did the water bead up on the surface. I have come to the conclusion that there is bleach in this product and that it shouldn't be used on stained decks that you aren't planning to strip and restain, as i am currently in the process of doing as a result of this product.

This stuff is unbelievable. One side of my house was a total mess. I was about to get estimates from power washing companies until a neighbor told me about this. I wish I had taken before and after pictures. It took about a minute, but what’s a minute? The house looks like new. My only issue, if you can call it that, is what it does to windows. Maybe I didn’t read all the small print. You have to rinse he windows really, really well or it leaves white streaks. I saw it in time and now I have clean windows too. It worked great on the downspouts. Have to get more so I can do the rest of the house. I can’t recommend this highly enough. Truly unbelievable. If I had seen a video I wouldn’t have believed it.

My deck was in pretty bad shape as I hadn't cleaned it in years (don't judge!). I bought a really stiff narrow broom to scrub it with. This was a great idea. The broom is as wide as two planks. I was slowly cleaning section by section over a few weeks by pouring in some diluted detergent (actually a cheap laundry one I had in the garage) and then scrubbing the heck out of it. This worked, but was very labor intensive. I decided to check YouTube for qualified reviews of different cleaning products. One man tried out seven or eight products down a long fence. He'd spray the product over a section of fence. This 30 Seconds Outdoor Cleaner came out on top in his test. I ordered it and decided to test it on a small part of the uncleaned deck. I left it for five minutes per the instructions and even scrubbed a bit before rinsing. What a crock! It didn't clean it at all. Here's the really bad part -- when I went to scrub that area with my trusty detergent and broom it had become incredibly difficult to clean. I estimate that for the same effort poured into the same area of deck, I got off only 20% of the dirt/mildew/misc. that I did before 30 Seconds Outdoor Cleaner. I still haven't gotten that small (thank goodness) test section clean and it's not for lack of effort.This product has ostensibly "cleans" with bleach. I wish I had tried one of the Spray and Forget family of products that works slowly, but on its own without scrubbing. I'm afraid that I no longer have that option because the bleach has killed any organic material for that type of product to eat away.
