30 Seconds Deck Cleaner Review 2022

30 Seconds outdoor cleaner cleans algae, mold, and mildew from anything outdoors. 30 Seconds Outdoor Deck Cleaner can be used on a variety of surfaces; wood decks, concrete driveways, sidewalks, stucco, vinyl siding, brick walls, plastic outdoor furniture, you name it. If it’s outdoors and dirty from humidity and wet weather, 30 Seconds can clean it all. Simply spray on and hose off. It’s clean when you want it clean.

Note: We used the 30 Second Cleaner for prepping a wood deck in our test results.

30 Seconds Deck Cleaner Rating (1-10)

Removal of Graying, Dirt, Grime: 5

– The 30 Seconds Outdoor Deck Cleaner did a poor job of cleaning and removing the graying. The cleaner removed mildew and mold, but it does nothing to remove old deteriorated coatings and oxidation/graying of the wood. It lightened the color of the wood slightly. On inspection of the contents, it is basically bleach with soap additives.

Cost Per Square Foot: 7

– Cheap for a liquid outdoor deck and mildew cleaner but since it does not work very well, we could not give it a better rating here.

Ease of Application: 9

– The 30 Seconds Outdoor Deck Cleaner applies easily with a pump sprayer. No mixing is needed. Just fill the sprayer and apply. Consistency hasn’t any issues with the clogging of the sprayer.

Final Appearance of Cleaning: 6

– We were not impressed with the overall cleaning, just bleached out the wood somewhat.

Overall Score for 30 Seconds Outdoor Deck Cleaner: 6.75

– 30 Seconds Outdoor Deck Cleaner is a poor way to prep your wood or deck for a stain. Basically, is is just bleach with some soap in it. Bleach is bad for exterior wood as it damages the lignin or “glue” that holds the wood’s cellular structure together. Bleach is also bad for the surrounding areas and to use without proper equipment and or protection.

It does not show any corrosive warning label says biodegradable does not recommend wearing gloves yet I now have chemical burns on my hands and in a lot of pain . Will be contacting government oversight to report lack of adequate safety labels .

I followed the directions exactly as written. Results were awful. Try another product. If I could return an empty container back to the store I’d be on my way right now. Don’t waste your money.

I am a professional Painting Contractor, If I were rating this product on ability to clean surface alone it would be 4 stars, how ever I must say that it advertises it WILL NOT KILL PLANTS on multiple spots on label, FYI THAT IS A LIE. I have photos, killed about $1500 Worth of plants at a clients house, I am extremely unhappy and believe if they say it will not kill plants that they should reimburse my clients. Its not that it does that which annoys me, its that they say it doesn’t but it did, otherwise I would have covered plants.

I tried this product this weekend. When first using I thought it was great. However when I woke up in morning to a white fence I was pissed. Any help to get this white residue? My fence is cedar with allot of gray. What do you recommend? Thanks

to prevent damage to plants with 30 seconds, spray plants with water first and do not use 30 seconds in the scorching sun. As with anything, a little common sense goes a long way in making a project successful.

This product is garbage. Waster of money and time and deck looks bad after using it.
