Review: A time saver and money maker. Very happy with this product. Works very well. Best product I’ve used for leak testing - 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.
Review: Worked as described - 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.

### ⭐⭐⭐⭐⭐ A time saver and money maker. Very happy with this product. Works very well. Best product I’ve used for leak testing
*by B***A on June 12, 2018*

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.

### ⭐⭐⭐⭐⭐ Worked as described
*by D***. on November 11, 2021*

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.

### ⭐⭐⭐⭐⭐ Every homeowner should own a bottle of this
*by M***N on August 22, 2020*

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.
