I bought Urine Gone with the little black light and the light isn't strong enough to really show the urine spots. We ended up buying a large (about 2 feet long) black light. It looks like an under the cabinet light and I carry it around to find any urine spots. It works well but it does have to be very dark in the room and sometimes I have to get just inches above the area with the light.

One problem I found is that where I have cleaned before will often reflect and look like a new spot but it's just the cleaning agents I've used shining back. I also kind of freak out at how dust will reflect the light. The first time I saw little dust particles on the curtains I thought someone has sprayed my curtains. Thanks goodness it was just dust.

I've been using Urine Gone for about a year or so now and I thought at first it was really good but now I don't think as much of it. I wish there was a really good product to totally get rid of the urine enzymes. Nature's Miracle never really worked well for me either. Anyone know of anything that works great?
