Will this get rid of the stains showing under a black light? Will it pass a black light test?

I have no idea, the company sends you a list of how to's before the the product arrives. I am sure it will do the job though, because it eats the bacteria according to the directions.

Of course it will, any organic stains will fluoresce. In a darkened room it will light up the urine spots on the walls......among other places. :)

Good morning. This bacteria test kit does not NEED a black light (i.e. the lights in dance clubs, bars, haunted houses, etc. that make clothing and fluorescent colored items 'glow'). If the water sample turns color (bluish green) after the appropriate amount of time then the sample contains coliform bacteria and you will more than likely want to have the water tested by a certified water testing lab. Using the black light: If the water sample turns color (bluish green) after the appropriate amount of time and when illuminated by the black light it gives off a fluorescent glow then the sample contains, at the very least, E. Coli, a type of bacteria that causes gastrointestinal illnesses in humans and typically comes from human or animal waste. We hope this helps!

It will. It leaves behind a bit of residue, I suppose you will really be able to see it on the black. I sometimes clean, rinse and wipe with a micro fiber cloth to polish and take off any residue.

We used it to clean dark water stains on the ceiling in our motor home. The ceiling is carpeted to muffle road noise. It was highly recommended and we are completely satisfied with the results. My husband used a very stiff (vegetable) brush for the dark spots. You must have good ventilation and avoid drippings on your furniture or carpeting as it will leave bleach spots. SBP

Basically, I don't know. Best to check it when it is very dark. Indoors or outdoors doesn't make a difference. I've only tried my light on fresh urine. Apparently it's good for looking (?) at other stuff as well. Hope this helps a bit for you.

Yes and no it did not remove stains. It does however remove water stains from my outside windows but have to leave on for an hour or so then had to wet a magic eraser and go over the window then rinse clean and squeegee it.

It definitely picks up other stains. I read somewhere that carpet cleaning products are among a few items that the light picks up. You may want to Google it or check the Sellers website to be sure.

Yes, it will be very prevalent where the stain is. Works best in low/no light environments. Stain will show even after cleaned if in fibers of carpet but will be duller in brightness level.

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

No. It does not remove the light dark spot as the seller ad online. I am regret to buy it. It wastes the money to buy it.

It didn't really seem to work for me, maybe it would for you. Try the back of the couch or area not seen first to make sure it doesn't stain. Good luck!

Yes, this device will clear your check engine light. It also has build in programs that will change performance settings, such as economy mode and performance modes.

We had great luck with this. Follow the directions and yes it will remove the stains.

You need the black light to test for E. coli. A black light looks like a black or dark purple fluorescent light bulb. You can get a small one adequate for this test right here on Amazon for about $6.00. The Chauvet Handheld Blacklight (NVF-4)

Yes, it does detect some unknowen stains which are not removed when treated with the enzyme solution. I am curious to see if they will remain after the carpet is cleaned.

I haven't had black spot issue. But it did work well on a yellowing problem I had with the leaves. It might well be worth a try.
