30 SECONDS Outdoor Mold & Mildew Stain Remover Spray | Ready To Use | 32 fl. oz. | 2 Pack

I made this purchase to clean the vinyl siding on my home in Florida and it melts the algae away and takes minimal scrubbing effort. I sprayed it and left for 3-4 minutes and sprayed it off with a hose. I will purchase again.

I used on my outdoor white sunshades in my florida lanai which were covered in dirt and mold. When I first sprayed on the front and back the shade appeared to turn yellow. I thought oh no but I continued and sprayed the rest of the shades. After a few minutes the yellowing color was gone and the blinds were white. I rinsed the shades with hose and let dry before rolling back up. The shades look brand new. You will smell an odor of bleach while using. I would not use if windy outside. Definitely would buy again.One drawback, one of the bottles was leaking.

We were shocked at how well this worked! We have a couple sheds on our property that were looking a little green and thought we would try this to clean them up. This product was so easy to use and made the sheds look like we just got them! So happy with this purchase!

If you need to soft clean your house, it’s a very good item to use the only issue that I had one bottle I bought the nozzle worked great the second bottle. The nozzle did not work well luckily I had two so I was able to use the first one. works great on concrete. I cleaned 300 feet of vinyl fence with one bottle.

This product is a great way to quickly clean outdoor items. Yes, it is basically just diluted bleach with a small amount of "proprietary ingredients", but it does work and it's very convenient. I attached before and after photos of a shed door that I used this product on. I sprayed the door liberally with 30 Second Outdoor Cleaner, waited about 10 minutes and then hosed it off. I didn't wipe or scrub the door and these are the results. With a small amount of wiping/brushing or another application of the product it would probably look like new.

works to some degree...I worry about getting it on fabrics...I wanted it for mildew on outside rugs....it did work, but not as well as I thought....I need to use it again...not as good as I thought it would be

So I had power washed my shady, Northern exposure front entrance that consists of a concrete and brick porch and steps, bluestone stair treads, concrete walkway, and paver retaining wall. I had normally faithfully done this every spring and it looked great. However, for the last 4 years, I had skipped this chore and it looked bad. This year, I got out my power washer and things cleaned up beautifully as usual. I had removed all the thick moss and algae, but I still had some green and black spotting that remained. I decided to buy this to treat everything I had just power washed in order to get rid of the remaining stains and hopefully slow down any regrowth. I applied this as instructed. The sprayer is pretty precise with no overspray so it wasn't messy or worrisome. Getting it on my clothes, skin, or shoes was not an issue, and wearing gloves was not necessary. While the sprayer worked well, the wand is way too short. Because of this, you have to work completely hunched over, and I'm a short 5"2". The wand should have more foldable sections, like the wand that comes on RoundUp Weed Killer, so you can stand upright while spraying. Also, because you have to squeeze the trigger the whole time, the application process gets tiresome. My porch floor only measures 6' x 8' but doing a whole large patio or driveway with this applicator would be hugely challenging. As for the 30 second claim, don't waste your time or money. I left it on for 15 to 40 minutes depending on the area. The 40 minute area of my porch floor looked mildly improved. Any shorter duration was completely ineffective. The stairs which were left for 20 minutes and retaining wall left for 15 minutes, showed no improvement. Because it was getting dark out, I couldn't let those areas sit any longer before rinsing them. Given the non-results and the tiresome application process of working hunched over with the too short wand, I would never recommend this for use on any large areas. At over $30.00 a bottle, and no dramatic results, I wouldn't buy this again. At least not for this purpose. The results were very disappointing. It did nothing that my power washer didn't do, and the power washer was much easier to use.

I bought this to clean the garage door and was blown away by how well it cleaned things up. I also used it on the shutters and patio furniture...everything turned out great, clean just like I like it. Excellent product but the bleach snell is pretty strong,m.

A severe windstorm last year caused the siding on the house to be imbedded with dirt and grime that we were unable to remove. We heard about 30 seconds outdoor cleaner and decided to give it a try. After spraying down the siding, and waiting a few minutes before rinsing it off about 90% of the dirt and grime was gone. A but of light scrubbing removed the rest of the dirt and it now looks like new. Great product!!! Next time for a bigger job I will get the large size with the attachable hose.

I've been using this product for years. It works as advertised.

It was difficult to choose whether to purchase the trigger spray, pre-diluted, ready-to-use version, or the larger bottle which needed to be diluted before using. I had been advised to use this cleaner to remove soot and residue from my soffit and exterior wall, after using my natural gas fireplace all winter. After two separate tries made by a professional cleaning person, 30 Seconds Outdoor Cleaner did not erase or dissolve the soot and marks completely from my wood siding, or the metal soffit and gutter above. There is some improvement, but not the complete cleanup I was expecting to get from the effort put into the job, or the extensive list of surfaces for which it was suggested. On top of my disappointment with the result, there was the expense of purchasing the product; consequently, I cannot recommend this cleaner with any degree of certainty of its success, or value for money spent.
