For daily cleaning, this stuff does the job. But it isn't that effective when used as instructed for the bimonthly flush (pour down 2oz). Doesn't clean out the gunk and if not careful, waterless urinal will clog or get slow. Once that happened to my units, the fix and product for bimonthly cleaning is EcoScale. [...] I use that instead of the Kohler cleaner and the pipes run clog free.
