Black light is also know as ultraviolet, or UV, light. UV light, simply, is light with a frequency higher than violet visible light. Just think of a rainbow. Water crystals break visible light into a spectrum where red has a lower visible frequency and violet has a more highly visible one. Black light has many applications. For example, most money bills and some documents have markings that are visible under black light only, to prevent counterfeiting.

Majority of urine absorbed below the surface — common on furniture as well as other highly absorptive objects, urine can be absorbed deep below the surface with very little if any detected at the surface. Used batteries can deliver markedly lower UV light output and therefore the resultant weaker glows can make finding urine stains difficult. Dark or patterned surfaces — darker colours absorb more light, reducing glows. Patterns make seeing edges of glows more difficult. Other types of glowing stains that cover suspect areas, such as those from cleaning fluids or some types of food, can also add to the confusion.

Lighter coloured carpets, often of the same colour as dried urine, could create glows under UV. This could well be because you simply have not looked around hard enough! Pets can appear to be very creative with where they urinate. Cats in particular can sometimes pee in the most seemingly unlikely places, such as on book shelves, behind doors and under tables or settees.

If not, or you believe your unit is faulty in some other way, contact us and we can discuss issuing a free replacement! In cases of potentially large amounts of urine, such as when it has seeped through many layers of carpet or deep into furniture you may literally need to dry the area for a few days, or up to a week at normal room temperature.

Dry urine has a much more crystalline structure which is able to provide the greatest glows possible. If you can stomach the smell, faster drying may be achieved by novel methods of removing moisture, e.

Moisture meters are a good extra tool for locating wet or dried — due to its wicking nature it is always at least a tiny bit wet! One way to assess glow strength is by absorbing wet urine onto dry white tissue, shining your PeeDar on it once dry. Outlines are also more visible since the glowing surrounds are strongly a different glow colour to the urine.

Such lighter carpets also have the added bonus of actually showing up some stains in normal daylight. Lastly, finding the source of the glowing material can be difficult, UV lights simply highlight all fluoresce-able substances. Cat urine can often have a faint light green tinge. Cat urine glows usually have spray or pool-shaped outlines, sprays are usually on more vertical surfaces, regular urination is typically on horizontal surfaces.

Cat urine often has a very pungent ammonia smell too. Dog urine reportedly usually has less of an ammonia stench, older stains can sometimes not give off much smell, but generally all urine is usually unmistakable when sniffed close enough.

Food glows are highly variable, from nothing to extremely vivid e. Some juices such as orange juice show up as a deep red. This is a complex area as you are probably beginning to see. Please do tell us how you get on! I purchased the PeeDar LED flashlight and put it away,last year, and then found my toy poodle had soiled my rug as not only could I smell it, when I pulled the rug back it is an area rug , I found lots of staining on the pad.

I had the rug professionally cleaned, but I found some new spots on the pad recently as again smelled an odor. I recalled getting the PeeDar, put it new batteries, tested it on white paper for the blue glow, but despite using it the dark with curtains closed, cannot find the stains on the rug. It is patterned rug with a white backround.

I have even tried using my prescriptions sunglasses with no differnce. Any suggestions as I know the urine is there? Unfortunately the best way to do this is by getting a dry white piece of tissue paper and dabbing it a few times, in a very slow and deliberate manner, with some downward force, on the various perceived soiled areas, especially what you regard as the centre of the urine spot.

If moist urine is present is should stick to the dry tissue, even the presence of very small visible droplets of moisture are a sign that more drying could be a good idea. The white background of the carpet should glow very strongly generally, this usually means stains on it will be much stronger too, although there can be the rare case of a more unusual material simply not glowing much. Fluorescein, a harmless dye swallowed by your pet and peed out over a few days, glows extremely strong under UV even when wet, ideal for when moisture may be affecting fluorescence, or pet urine is simply not that glowable.

Ask your vet about this dye, he may be able to provide it. Also, kudos on being so wonderfully explanatory as well as informative! This is Uber confusing to me and I had a science degree.

Either way, wonderfully written article for such a complex subject, and fantastic tips to boot. Well done! My grateful thanks. Are there specific UV lights that detect pet fluids such as their urine or is it all UV lights that show bodily fluid? Also even after a carpet had been cleaned several time with a carpet cleaner could spots still appear under the UV lights?

Many thanks for your message. This seems largely due to certain chemicals in urine reacting with the UV to give the greatest quantity of visible light, the sheer quantity of UV, and very low amount of visible light, produced by the LEDs.

Good luck with your stain hunting and removal.

What do you suggest to do with dark carpet?? Is there glasses or some kind of spray that will make it show better? Apologies for the lateness of my response! Black or dark brown have shown reduced glows in tests too. The darker the colour the more light will get absorbed. As with any UV light, all you can do is try to see if it works, following the advice on best practice, in the article above.

PeeDar UV is not aided by tinted safety spectacles, a clear colour is best for seeing all glows at their brightest, and in their individual colours. For situations where detection seems impossible, generally your only two options are to clean or replace your carpet. It goes without saying that this can be quite expensive. My daughter just recently had her carpets checked for cat soiling…..

I have never known her two cats to ever mark or have an accident. However, my daughter was on TPN at home for 4 months. Could drips or small spills caused the markings? Every bag did contain sodium phosphate and we remember making the comment that the TPN smelled like cat urine. Many thanks for your good question. Many different types of food and drink glow under UV. Cats that urinate inappropriately do so in a particular way e. Scanning your whole home, not just the carpets, for stains would help you gain a better idea of where they came from.

If similar stains, for example, were in hard to reach areas that only cats would potentially go to, you may have the answer you were looking for. Also, if the glows are not white, straw or whitish-light-green in colour, but instead a strong blue, for example, they are likely to be from a different source, in this case bleach from cleaning fluids. Becoming a bit of a detective is a necessity when determining the source of glows under UV, UV simply locates stains!

Once you treat the urine stain adequately, will it cease to glow? I have no sense of smell to tell if an odor remains. Many thanks for your question. Although stain detection is our business, we have learnt quite a bit about the even more complex area of cleaning up afterwards. When applying enzymatic cleaner, make sure to drench the area affected. Also, it is always a good idea to mop up as much liquid urine before any cleaning, and as much of the cleaning fluid as possible after the required amount of time for the cleaner to do its job has elapsed.

When these components come into contact with moisture they form uric acid crystals, this process releases odours which, although sometimes too faint for owners to smell, will often be detectable by your pet, and so promote re-offending in the same area.

Uric acid is said by some sources to have a half life time it takes to reduce in quantity by one half of 6 years if left alone, so it is very important to completely remove this particularly stubborn part of urine. After adequate enzymatic cleaning there should be no glows present from the stain at all. This dye glows a brilliant brighter urine colour even when wet, and can show where your pet has been urinating.

Lastly, the use of a moisture meter can help detect suspect wet patches on or near cleaned areas. Urine tends to glow in roughly circular shapes or tear drop shapes on flooring, or with a spray outline on more vertical surfaces, and with a light straw colour, sometimes with a light green tint if the urinating animal was a cat.
