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.
Black lights emit a type of ultraviolet radiation called UVA, which is invisible to the human eye. They are often used in industry, nightclubs or amusement parks to make things glow. This glow is the energy emitted by the light being converted into visible light by particles called phosphors.
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.

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.
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.
The lights cause materials such as bacteria, urine, seminal fluids and blood, to “fluoresce,” so that the naked eye can detect them. Typically, UV lights are used to test surfaces especially when there is a disease outbreak or any sudden increase in occurrences of a specific disease at a particular time or place.
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.

You can use a black light to detect body fluids. It’s actually a good way to look for pet urine or make sure a bathroom or hotel room is really clean. Cat urine, in particular, glows very brightly under ultraviolet light. Urine glows under a black light primarily because it contains the element phosphorus.
Pseudomonas Aeruginosa: The Fluorescent Bacteria.

Puddles are obvious signs a cat is peeing in a certain area, and there might be some older stains there, too. You can also use a pet urine detector, a special UV black light flashlight. Turn off the lights and make sure the room is fairly dark for best results.
The ultra-violet rays used by black lights use the same wavelength as biological waste such as urine. When using a backlight to find cat urine spots , turn out the lights and shine the black light over all areas of the carpet. Most urine stains will produce a noticeable glow.
Colors That Glow Under Black Light- Whites. White paper, paint and fabrics are treated with fluorescent additives to make them brighter.
Yellows. Bright yellows paints and fabrics will glow, due to the additives to make them bright.
Some of the spills a person might find with a black light include:- Biological stains: saliva, semen, urine and blood.
Laundry stains: dried liquid detergents.
Club soda and all liquids containing quinine.
Invisible ink made from lemon juice or similar compounds.
Toothpaste with whiteners that fluoresce.
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.
Does carpet cleaner show up under black light? Since carpet cleaner doesn’t have the same job as detergent, it may not appear under black light. However, if you have tried to use it to remove a stain that does show up under black light. You may still be able to see the stain when you shine a black light on it.
