Does cling to metal quite like the “blue bubbles “brand.

This product works great it was used to determine a possibility of a leak on a propane regulator and it does exactly what it's supposed to do we had no leaks but it also works for your air conditioner in your home on any of your outside fittings

As others have said about the spray nozzle being a straight stream and cant mist the spray in a broad area but besides that it works great .I Found my leak in just a few minutes and didn't use much soap, did waste a small amount getting it where it was needed. I would recommend this soap and maybe change out the sprayer with an adjustable one.

This is a great leak detector for car AC, Home AC, car tires and anything that requires leak detection. If you spray it on the schrader valve be sure to rinse it and then let the schrader valve dry before putting the cap back on it. Every homeowner should check their systems for leaks when the AC systems are restarted each year. This could save you thousands in repair costs if you have a small refrigerant leak.

Exactly what I needed. Found a leak at a fitting that was escaping my best efforts of discovering it. Easy to squirt on the pipe fittings and valves. Thick so it stays easy to spread around with a small brush in tight places where it is hard to squirt. I covered all the joints in the suspect line with this as soon as I got it and about five minutes later I saw the tiny bubble slowly forming. I was only loosing about a quarter psi over 24 hours and this found it. I took that joint apart, cleaned it up, applied fresh pipe dope, reassembled and my pressure test held rock solid at 15 psi for more than 24 hours with no loss.

This product identifies leaks well, but is very thick, so you use a lot more than other brands.

I have used leak detectors for years, and had never tried a spray version... It worked so well I will never use the other styles, your hands stay clean, it provides a more consistent coating and best of all, it blows the largest bubbles if you identify a leak.

Helped me locate a leak I had been chasing in a Mini Split AC unit. It was such a small leak, it would not effect operation of the unit for days. Within 3 minute I found and repaired the leak. A must have product. I have also started using it on Natural Gas Lines too.
