Minute Gas leak

I have a small gas leak either coming from my Gas dryer or my hot water heater. I tried locating it by using soap suds to no avail. I suspect its coming from the piping thats behind the dryer and its not accessable for testing as I have to disconnect it to pull the dryer away from the wall. So I turned off its supply valve to see if the leak stops while still letting the hot water heater operate from the main shutoff. My questions are:
Is there a product thats better then soap suds for detecting leaks?
What about the heater itself? Could it be that there is too much delay between introduction of gas at the burner and ignition.
Looking for ideas.

I generally use the leak detector soap that they sell at refrigeration supply houses, but it's basically the same as what you're using. It has fluorescent dye in the soap so you can see the bubbles a little better. The gas company most often will come out for free with their electronic "sniffer" and find the leak in a heartbeat for you. Trouble is, they can turn off your gas service, depending on what they find while they're there. You can buy a "sniffer" too, but they're quite expensive.

Even a small leak is not a good thing. I would suggest disconnecting the dryer and purchase a plug and then test the piping while plugged. This will let you know if it is the dryer piping itself. Use the soap solution on ALL connections and the valves. Make sure to check all around the controls on the water heater also. If it was a delay between gas flow and ignition, you should hear a POP when it lights. You MAY be able to rent a sniffer but I haven't seen them where I rent seldom used tools. Good luck.
If you have never made a mistake, you haven't done much.

I only noticed the smell about 3 to 4 times a week. With the dryer supply shut down, I will give it a couple days so as to isolate which is at fault.
