Question about Water Water Heaters
You can try cleaning the thermocouple with a piece of emory clothe or replace the thermocouple. Watch and see if the moisture continues, it just be condensation from humidity from the lack of heat under there. If the moisture continues, you may have an early leak.

It sounds like your flame detector (usually a thermocouple) has gotten weak and when you cleaned the pilot the stronger flame was able to generate enough power to keep the gas valve working. If you replace the thermocouple your problem should go away. If a new thermocouple will not keep the gas valve operating...the coil in the gas valve has gone bad and you will need to replace the gas valve assembly. (most valves do not have replaceable coils).

The thermocouple has failed. It is the temp probe that goes from the pilot lite burner area to the control valve. Go to your local plumbng repair shop and buy one. Most appliance parts stores have them also. Take the old one with you and they will hook you up with an exact replacement. They are not that hard to change. Usually a nut or 2 screws in the temp bulb area at the burner end and a nut that threads into the control valve.
Make sure before you install the new one that the area where it mates to the gas valve is clean. Should be about a 20 min job including clean up with replacement parts in hand.

Testimonial: "exactly what I wanted yo know. thank you"
At the controls there should be a knob that says " Pilot"... "ON" Turn the knob to pilot and hold it down while lighting the pilot lite. Keep holding it down until it gets warm enough that when you leave it up the pilot stays on. Once the pilot lite stays on on it's own turn it to on.
