Best Mildew Remover Ever!
Reviewed in the United States on April 30, 2025
Size: 32 Fl Oz (Pack of 2)Verified Purchase

Best mold and mildew remover EVER! Initially, we bought 30 Second for outdoor window sills that had become quite mildewed. They were disgusting, really. Well, on them in took two applications, but the window sills were like new in less than 3 minutes.

The product is so good, I ignored the "outdoor" label and squirted a few spots in the shower that showing signs of mildew. Squirt, wait 30 seconds and WALAA! No more mildew. If you're afraid of fumes, of which there are few, just rinse the area with water and you have a sparkling wonderful new-looking shower! No muss, no fuss. The cleaned area stays mildew-free for quite some time! Worth every penny.

Couldn't be any easier! Spray and forget about it.

This is the best product I have ever used!

Worked like a charm, but the sprayer bottle doesn't work well.
Reviewed in the United States on March 31, 2025
Size: 32 Fl Oz (Pack of 2)Verified Purchase
It really did the trick on whatever the black stuff was on my composite decking that even my power washer couldn't remove, but the spray bottle it came in leaves a lot to be desired. I didn't have a big area to spray, but still, it took twice as long as it needed to because of the ineffective sprayer. I'll be transferring it to another bottle.

Update: It just saved me again with getting the squiggly spots off my new paver patio from catkins.

Size: 32 Fl Oz (Pack of 2)Verified Purchase
I have a cold plunge on my back porch (concrete). It was gathering a green and grey film, either algae or mold/mildew type of stuff. It was growing in both the sides of the cold plunge and on the concrete floor. This stuff cleared up the stuff on the side of the cold plunge in SECONDS after spraying, didn’t even have to scrub. The mold on the concrete took some scrubbing but came completely off. I moved the cold plunge to an are that gets more sun and breeze. No more mold/algae.

This stuff worked on concrete and plastic. It does smell like bleach like the reviews say but what do you expect…the smell goes away too. It’s fine. WEAR GLOVES! 5/5

Bring a brush.
Reviewed in the United States on April 20, 2025
Size: 32 Fl Oz (Pack of 2)Verified Purchase
Bring a brush, because this stuff is ineffective. You can saturate the surface of a white vinyl fence all you want, but when you spray it off 1 minute later, nothing comes off. Nothing. It needs to be scrubbed. I bought a two pack and the first bottle’s spray nozzle didn’t work, so even more dissatisfaction.

Reviewed in Canada on October 30, 2023

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.

Very expensive, and failed to produce the necessary results. Disappointing.
Reviewed in Canada on August 31, 2024
Size: 32 Fl Oz (Pack of 2)Verified Purchase
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.
