Urinal salt deposits

[GGorman04]

I have a restaurant with a urinal. Every 6 months or so the urine must harden so bad that I have to take the urinal off and flush the debris out. Before I removed the urinal, we tried Draino and Bio-Clean with no luck.

Is there another type of cleaner that would soften the urine buildup so that removal of the urinal was not necessary?

Sounds like the urinal does not have an auto-flush and the patrons are not flushing it after each use. The "if it's yellow, let it mellow" tree huggers are overly concerned with saving water.

Some plumbers use an acid, but that doesn't seem very safe to me.
Then there are the enzyme screens you can use like these.

Thanks for the advice.

The urinal cake thing caused me to run across "urea monohydrochloride" because it is an ingredient in many urinal cakes. I am wondering how that would do against toilet bowl rings compared to some other acids. It is milder than phosphoric it seems, but may be more effective. That may be hype.
