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: Great product for reassurance! - Smelled gas from the stove and had a technician come assess; he used something similar to this product and I didn’t fully trust his assessment as I swear I thought I saw some bubbling! So after he left, I Bought this item to do my own testing! It arrived quickly and gave me the reassurance I needed that my stove did not have a gas leak! Quick tip for using: The item comes with an applicator; I noticed that the liquid has some bubbles just from shipping so I let it sit for a bit before I applied it, as when I first applied it the natural bubbles from shipping made me believe there was a leak- just a heads up! (FYI the way I pushed some of the small bubbles out quicker was by gently banging the bottom of the item on the counter a few times!) enjoy!

## 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
