This is a great product and is very easy to use.

Works great, second time I orordered it the bottle was leaking but the seller quickly refunded my money. Great product and great service

We purchased this to confirm if our neighbors sewer was indeed leaking into our basement. They flushed it down their toilet and the green dye all over our basement was proof positive. Possibly saved a legal battle and a friend.

I didnt use it for what its intended for but I know it will work great for it!! I used mine for Halloween to make my skeletons look like their drinking an puking posion!poison!! And I pour 1 cup liquid to 4 gallons of water and it turned neon green! You can see the neon in the day with out UV light or with UV and it looks amazing!! My Halloween props looks amazing with it!! And im sure I have enough to last me for 2-3 years!!! Love it so much!!!!

When my sons truck began to have radiator fluid leak issues, we tried to find the problem area but there was so much gunk on the engine block, it was difficult to tell. We put some of this fluid in the radiator (dont need to use much) and started the truck, then used an inexpensive UV light to see where the leak was. Worked like a charm!

Solved my problem!

fast shipment , found leak quickly !

I had an issue in which one of the waste pipes within a house underneath the basement slab was cracked and was leaking into the french drain and ending up in the sump pit. To isolate the source, I added a small amount (4 ozs) of this tracing dye to a 5-gallon bucket of water. This stuff is orange in the bottle, but wildly flourescent yellow-green when mixed with water. It worked fantastically well, and we quickly isolated the source. Following the directions, we had also purchased a UV blacklight to more easily see the colored solution in the sump pit, but in our case, it was so obvious -- and so yellowy-green -- that we didnt really need that UV blacklight. FYI, the seller was very prompt with delivery and we received this without any leaks. For this particular application, I highly recommend it.

My dishwasher was leaking and I couldnt for the life of me find it. A little dye and a black light flashlight and I spotted the leak in 5 minutes. Saved a bunch of time and money.

This stuff is brilliant--in more ways than one! Its super concentrated and super visible, and allowed me to sort out the bizarre drainage system on the property I recently purchased. Im totally satisfied.
