THe only thing special I do is put a few shallow cuts in the top of the dome to allow the gas to penetrate quicker. Drop the star with the emitter on it into the gas and let it sit overnight. Every now and then I swish the gas around in the jar before going to bed and in the morning the dome is gone and the emitter perfectly clean. I pluck out the star with tweezers then rinse it off in a shot glass with clear rubbing alcohol to remove any petrol smell. Set the star down on a paper towel until the alcohol evaporates. That's all there is to it. 8)
Ken, never use construction adhesive or regular glue. You need to use an adhesive that is thermally conductive. The most common used are Fujik and Arctic Alumina. It takes very little to properly adhere the star to the pill/host and the less you use the better it is. You want only a super thin film to be between the two metal surfaces so that maximum thermal transfer from the emitter MCPCB (star) and the host.
Fujik comes in a big tube and is cheap, available from The standard Chinese sellers e.g: DX and fastech. It is like a standard glue just plain white and stays a bit rubber like after hardening.
AA is a lot better in terms of thermal conductivity and is usually available from computer and electronic stores, just check your local internet dealers. AA is a 2 component glue which gets quite hard.
