I have a MasterCraft propane grill. It seems to have a leak. The propane is getting used up far too fast. This is the second tank where this is happening. I was thinking I should get some soapy water and try to find a leak. Any suggestions of how to do this? Do I spritz the soapy water on hoses, connectors, etc.? Do I did a sponge in the soapy water and somehow get it onto the hose, etc.? I remember seeing a plumber do this to check a connection on a stove, but I don't remember what he did to get the water onto the connection.
