Clep, I do the soap and water mixture to find leaks. with an eye dropper, simply pour a little soap and water mixtures around the pad and then blow in to the melodica without pressing a key. If there is a leak you will see a bubble there. Once you see a leak you can repair that pad one or mark with a grease pencil or blue tape and move on to the next one. After doing this several time I have found that doing only one at a time is best because if you do several at a time the water mixture and bubbles can disapear and you will not know if there is a leak. You can do this at anyplace there is a possiblility of air leaking it works every time.
