Instead, try using a UV light, also known as a black light. If you shine the light in a dark room, cat urine will glow yellow or green, making it easy to see exactly where you need to clean.
Rather than putting your nose to the floor trying to discover where that smell is coming from, you can find dried urine stains on carpet and furniture with a blacklight. Unleash your inner scientist and scan the light on your floors to find the stains.
You can buy a blacklight flashlight from internet retailers such as Amazon and Ebay. The there is a compound in dried cat pee that will glow a green color under a blacklight. Shine it everywhere, including on walls where cat pee may be sprayed or splattered so thin that you wouldn’t have otherwise noticed it.
In a nutshell, there isn’t quite a difference, but a misunderstanding of the terms. Black light is nothing but UVA light, while UV light is basically composed out of UVA, UVB and UVC. So in other words, black light is UV light(450-100nm), covering the 400-320nm spectrum.
Many UV lights emit a wavelength of 390 nm to 400 nm, allowing you to detect dog urine and common household stains. For cat urine, however, it is best to use a light in the 365 nm to 385 nm range. These UV lights tend to be more expensive.
Vitamin A and the B vitamins thiamine, niacin, and riboflavin are strongly fluorescent. Try crushing a vitamin B-12 tablet and dissolving it in vinegar. The solution will glow bright yellow under a black light.
Semen fluoresces blue between 300-450 nm, in the ultraviolet range. The invisible (to us) UV rays doesn’t interfere with the fluorescence, so forensic experts can see the stains clearly.
Some of the spills a person might find with a black light include:- Biological stains: saliva, semen, urine and blood.
Black lights, also known as ultraviolet lights (UV), are often used in professional cleaning to help detect if hidden pathogens are present on walls, high-touch areas, ledges, furniture, and scores of other surfaces.
UV light is used to detect the presence of trace evidence in forensic investigations. Blood, urine, semen and saliva can present visible fluorescence. UV or black light reveals changes on the surface of objects as it causes specific fluorescence in materials depending on composition and age.
Using the sun has been a popular method of stain removal for nappies, and many believe that the sun sanitises. With enough of a decent detergent, adequate agitation, and if needed a laundry booster, stains will be removed by the washing machine.
They’re a familiar sight to most, but America’s only marsupial has a secret: beneath their furry exterior, opossums glow hot pink under the right light – not headlights, but ultraviolet light.
Petroleum jelly, such as Vaseline, which glows bright blue under a black light. Ripe bananas glow fluorescent blue under a black or ultraviolet lamp.
Whereas urine that’s sprayed typically shows up on vertical surfaces (e.g., furniture, walls, etc.). If you’re able to catch your cat spraying/marking in real-time, you’ll most likely see them standing with their back to their vertical “target” and holding their tail held straight up.
Trimethylaminuria is a disorder in which the body is unable to break down trimethylamine, a chemical compound that has a pungent odor. Trimethylamine has been described as smelling like rotting fish, rotting eggs, garbage, or urine.
Old Cat Urine
Use a blacklight to identify exactly where the stains are located. You can try thoroughly soaking the affected area in an enzyme cleaner and extracting it with a shop vac. If this doesn’t work, then it is time to call for professional carpet cleaning.
As mentioned above, fluorescent tubes use the same technology to create ultraviolet radiation as the UVC bulbs, but they use different phosphors to convert that UV radiation to visible light. The phosphors absorb the UV, making them safe, and emit visible light.
Here are a few things you might have in your house with that glow under UV: Tonic water – the quinine in tonic water glows blue. Honey – the aromatic molecules in honey can glow green. Turmeric root – the curcumin in turmeric glows yellow.
Do all diamonds fluoresce? No. Only about 25% to 35% of diamonds exhibit some degree of fluorescence in reaction to long-wave UV light.
And if you don’t have a laser handy, a trusty black light intensifies pure olive oil to a bright yellow.
Just as human body secretions are visible under a black light, so are the urine, feces and other body secretions of animals. Black lights are useful for finding the unknown location of pet urine odors and for finding evidence of rats or mice lurking in your home.
A UV (ultraviolet) Light will locate and illuminate body fluid detection for semen or vaginal stains, invisible to naked eye.
