I found one on amazon that is really amazing. My son wet the bed once without a mattress protector on the bed, and I got this stuff to spray directly on to the mattress. It worked wonderfully. It comes in a clear bottle with blue, red and white writing. It can be sprayed directly into the air, directly on to fabrics, or mixed with water as a cleaner. I will do a quick search and see if I can't find the name.....
Kids n Pets brand seems to have good reviews - that is not the one I am thinking of.
Found it! - http://www.amazon.com/X-O-Odor-Neutralizer-32-oz-Concentr...
Good luck!
