Depends on what your cleaning
I used 30 seconds cleaner on my composite deck. I sprayed it on, waited, and then scrubbed it with a long handle scrub brush. After rinsing i was pleased with the result. IT’s not without effort, but better than getting on. My hands and knees and scrubbing.. Took some to my son to use on his concrete patio. Using the same technique we were very disappointed with the result. It appears this surface needs power washing with a scrubber head. I think these cleaners over promise. So good on composite, failed on concrete.
