Human urine is not nearly as concentrated as most pet urine. So, the odor and stain are generally easier to remove.
I have not tried the Judson Quat product, but from the reports I hear, I expect it would work fine for the odor. Flushing with water should take car of the stain.
CTI's OSR would be another option. That always worked good for me.
If you find you need something additional for the odor, give Hydrocide a try. No strong fragrance. It simply gets rid of the odor. Use at 4 ounces per gallon.
If you have a stain remaining, Stain Zone will take care of it.
Of course, nothing I say qualifies as the "official Mikey's Board" solution for anything. But I will stand behind this advice if Mike won't.
