While I hesitate to ask, I have been traveling for work for more than 20 years. The cleanliness of hotels has gone down. Does this light detect seamen stains or otherly body fluids?

It does show urine very well. We got it to find that due to having cats. Good luck and I hope all shows well in your stays.

I have never looked for that, but if you watch Forensic Files or something like it they use it for that. Just be advised, the stains will show with just the light but if you buy some yellow glasses (they show commercials on TV for them to help with night vision, I bought some at Walgreens) the stains will glow brightly. Much easier to see with the yellow or amber glasses.

You are thinking of black lights that show stains. This is a UV light that kills germs, not the same as black lights.

It will work anywhere there is surface-level urine. You can usually still find spots after cleaning, you just have to look a lot harder and get the light closer to the carpet. Sometimes though, if you have thick padding under the carpet, the surface of the carpet can be perfectly clean but the padding can still release odor. Lights wouldn't help in this instance.

Yes. Before you use this in water, you should use a paper towel and test it.

Absolutely! Make sure you get the yellow glasses. At my house it pops like a bluish- purple florescence. After you clean the urine spot it will still show under the light but very faded. Excellent purchase.

If it it the cleaner that you are asking about I can tell you that it leaves a white film on mine. I don't like it!!

I'm not sure about all stains, but I checked it on carpet stains and they glow brightly.

I'm not sure about the black light test. I do know that it removed the stain and the smell.

There is some light, but its not as bright as other purifiers I have. Its a weak green light. I took it out of the bedroom, though, because the motor makes a frequency range noise I don't like while trying to sleep.

You're right. I had to figure out what to look for because some fuzz and other debris can show up under the light. However, once I saw the first spot of urine, I knew what to look for from then on. You should point the light directly over the carpet and look for spots that resemble a water spill. Those are usually urine. Also look for areas on the wall near the floor that look like someone sprayed a water bottle. Once you find the first one, you'll recognize it from then on.

I can't speak specifically for puppy urine or vomit, but I used it to remove my son's urine from my microfiber sofa. Your question intrigued me and I happen to have a Stink-Finder Ultra-Violet Light. I pulled it out and ran it over the sofa and there were no stains visible at all with the light. I hope that helps.

I have made sure the room for mine is dark and the urine stains (and other stains) are dried. This is when it starts forming the fluorescence crystals that make it show up. If the urine or stain is still wet, the crystals that will fluoresce under this wavelength will not show up as the the neonish yellow/green or brighter white (colour depends on the stain / fluid type as well as how long it has set).

It's best to use the light in a darker environment to see any stains. So do it in the evening and turn the lights out to get the best results and prepare yourself as it could be pretty shocking. :)

When the unit is on, there is a small green light that glows (and guides me back to where the bed is when I get up to go to the bathroom in the middle of the night!) - you could probably put a small piece of gaffer's tape or electrical tape over it if it bothers you. Although I am usually quite sensitive to lights in the bedroom, this one doesn't bother me. I keep the unit on my tile floor near the bed so the light is quite low down. If the unit runs out of water the light becomes red. I find the unit quite effective even on low or medium, so it would only run out of water overnight if it started out with a low amount of water.

this black light is used primarily to detect pet urine and the distance it makes the urine glow is determined by the amount of light and darkness where the urine is located...i use it to test for antique vaseline glass and it makes this glass glow at well past 25 ft. with this portable black light, it does a jam up job for it's purpose...just buy one and see...i answered this question as best determend for this lights use...but in the wording of this question using the word wavelenth, can only be seen using electronic equipment that measures light...

Put batteries in light and shine on floor and walls and urine marks will show up.works better in low light. Best to wear the yellow googles supplied.
