    You will still experience a glow most of the time. For the details on why that happens, read my manual on how to deal successfully with urine. Free copy emailed to anyone who asks scottw@bridgewatercorp.net

    Hey Scott, didnt you post a chemical by CTI or something that combats this very problem?

    That Username guy was just asking me about this.

    There was a product from CTI called Black Out, that hid the glow or fluorescence caused by urine. This is no longer being manufactured. I am not sure of why they decided to remove this product from the market, but I do know that some issues came up because the product was water soluble and cleaned off. So stains once hidden could reappear. Imagine a situation where the next time you clean for a customer, stains that you thought were gone can now be seen. For an apartment renter that could be a problem when you are ready to move out. You get the carpet cleaned and now it appears to have new urine stains, but you never had a pet in the apartment!

    My personal experience with this problem has been that after only 1 or 2 cleanings you can still really tell where the stains were under a black light, but they don't look the same as the new stains. Hard to describe, but true. Also, I've noticed that urine rinse agents (acid rinses) do help as well as your regular acid rinses from your extractor. I've seen all the UV glowing go from very noticeable to completely gone in some cases. I don't know the scientific reason for it, but seems it must be the urine salts or something in the urine that is glowing and it can at least be helped or even removed by acid rinse. Sometimes pretreating each stain with a urine acid rinse and giving it plenty of dwell time will help a lot. Any supplier should stock a urine pretreating rinse and likely several of them. In some cases there may be dye damage that the UV light may still show up as a very bright spot, almost white, under UV light. You may not even be able to see the spot at all under normal light. This is the best I can describe it and yes it is normal.

    I always tell them (whether it's true or not) that the uric acid damages the synthetic fibers in the carpet, and it will always reflect to a blacklight, even after the salts that cause the odor and the yellow dye is removed from the carpet.

    This seems to satisfy the customer. Just make it sound like you know what you're talking about and after you remove the yellow stain and smell, they'll be happy
