Hi,
There's actually a description in the "tips" section at my website that should help you with this. Basically, there are actually two parts that will help -- the first being prevention. As cats tend to pee in pretty much the same area all the time, I always recommend a "rake and stir" every few days. This will help the crystals last longer by distributing damp ones and letting them release moisture, plus it will re-distribute that concentration of pee in that one area.
The stain is actually urine solid buildup on the tray. What I do is use Lysol Kitchen cleaner, and let it soak for a few minutes, and then take a scotchbrite sponge to the area. Works great!
Hope this helped!
