30 SECONDS Outdoor Cleaner 2 Pack with Hose End Sprayer - Cleans Stains from Algae, Mold and Mildew on Vinyl Siding, Deck, Patio, Brick and More

The back of our house was covered with algae, mold, and mildew; and there was some on two other sides of our house, as well as sections of our fences. We received outrageously high quotes from a few house power washing companies and we were considering what to do: 1) expensive power washing company; 2) getting on the ladder and power washing it myself; 3) find another solution. I found a YouTube video of a guy showing how well 30 Seconds Outdoor Cleaner works and decided to give it a shot. Every house is different and the level of work needed varies, but I was hoping we would get similar results to those shown in the video. This stuff works incredibly well and it is easy to use. I spent two hours on a Saturday morning and sprayed three sides of our house (front didn’t need it), a few panels of our backyard fence, and our two front yard post-and-rail fences. I would spray a section, move to the next, then go back to rinse the previous section after giving the product about 30-60 seconds to do its work. When rinsing after the brief wait, everything just came right off. No power washer, no ladder, no expensive power washing company. This product worked amazingly well and I saved approximately $1,800 compared to one of the power washing company quotes I received. I highly recommend this product.

This siding cleaner truly worked like magic—my siding looks brand new and I was amazed at how easily it lifted off years of grime. As other reviewers mentioned, the product does go quickly, so it doesn’t last long, especially if you’re covering a larger area.I followed the directions carefully and rinsed off all the surrounding plants right away, but unfortunately, it still caused chemical burns on the leaves. Most of my plants are now severely damaged, which was really disappointing. I also accidentally got some on my clothes and it left bleach marks, so be sure to wear old clothing when using it.Great results on the siding, but if you care about your landscaping or wardrobe, take extra precautions.

Easy to use. Product works exactly as advertised - spray on, let sit on surface, rinse. Cleared my north-facing siding all the way up to second story without need for ladder. Just my hose and the cleaning solution with included dispenser adapter. If you apply and scrub, your surface will be like new. I chose just to apply and rinse. Siding still looks fresh and clean, though if you walk right up to it, you can see some minimal, faint residue in some areas. For sake of convenience and time, apply and rinse works great. Only reason it's not 5 stars is that there was some minimal leakage during shipping due to the caps of each of the bottles allowing small amounts of solution out - likely due to the boxes being stored incorrectly in inventory and/or during shipping.

I can’t say enough good things about 30 SECONDS Outdoor Cleaner. This product truly lives up to its name—it delivers fast, visible results in less than a minute! I used it on my patio, siding, and even some old lawn furniture that had seen better days, and the transformation was incredible. Years of built-up grime, mold, and algae literally vanished before my eyes with minimal scrubbing.What really impressed me is how easy it is to use. Just spray it on, wait 30 seconds, and rinse it off. No pressure washer required, no elbow grease—just quick, professional-looking results.If you’re looking to bring life back to your outdoor surfaces without spending hours scrubbing or investing in expensive equipment, this cleaner is a game-changer.

Fantastic product. Truly surprising how well it works. Bought and used as a last minute attempt to clean siding before paying for power washing. Sprayed on and rinsed off and siding spotless. This is an amazing product. The only drawback is that you may need to increase your water pressure to reach higher homes a two story easy but if you have a third level it gets tough.

Best product I’ve used to clean the siding when algae builds up on it. Being that there’s a lake behind our home. Easy to use. Worked immediately removing the algae as I sprayed the vinyl siding. Beats other stuff my husband was using. Works great. Being that we bought the house with the disgusting thick algae. Guess it was safe to assume the previous owners didn’t do it. According to my new neighbors the previous owners only resided here 3 yrs. Must’ve been 3 yrs worth of algae. This stuff truly works.
