Worked very well
We had neglected off-white stucco wall around our back deck way too long - had become definite gray (& very dark gray, almost black when wet; Even had bits of actual moss in some stucco cavities (which I hand-scraped off/dug out) ). The 30 seconds solution took 3 attempts, but did get it back to original colour - this was pretty amazing - it was baked in so badly. PS: On round 2 I tried full strength but didn't seem much better than diluted 1:1. So for the remainder I stuck with 1:1 ratio, but left it > 15 minutes, keeping it wet, plus used a scrub brush on the worst areas, which definitely helped. This has got to be close to a worst-case scenario and it still did the job. I'll never neglect it this long again - would easily just need a single application for light jobs and if smoother surface. See photo: right side: untreated; left side one application (needs 2nd to get it completely clean if fussy).

I preferred to use Olympic deck cleaner which I have used in the past with excellent results but it was unavailable in my local stores so I read reviews on the 30 Second deck cleaner concentrate and chose it based on the reviews. I mixed 2 parts of water one part of concentrate and waited a little longer to rinse per instructions and was disappointed in the results. It released some of the algae but struggled to do so. I even resorted to using my small psi power washer to rinse it and although it helped a little the end results were not even close to what I had in the past with my Olympic product. I still have quite a bit left so will likely try it again in case it was something I did wrong and will use it at a 1 to 1 ratio next time. Overall it worked somewhat but not to my expectation.
