Review: Works so much better than soapy water! - I found a very slow leak at a Schrader valve using this. The bubbles are durable and thick so unlike soapy water they don't dry out and pop before they have a chance to work on a small leak. In this case I put a small hole in a valve cap, twisted the cap on the suspect valves and applied the bubble solution to the hole. It took about 30 seconds to see bubbles appear where my normal bottle of soapy water showed nothing. Amazing stuff!
Review: Good product - A good product for finding leaks in a mini split line set, would recommend for anyone doing their own mini split installation.

## Questions & Answers

**Q: How is this applied? Does it have a small brush in the bottle?**
A: Yes. There's a small 'dauber' attached to the underside of the lid. It isn't strong, so use carefully.

**Q: Does this detect natural gas leaks**
A: Yes, even low pressure gas leaks will still bubble up. Be sure to cover joint completely and wait a few minutes to check for bubbles.
Bigger leaks should show quickly.

**Q: Can I use it to detect a gas leak in a tube made from silicon?**
A: Possibly

**Q: Will this freeze if I leave it in my truck in the winter?**
A: Well, I live in New England and has never frozen up on me
