Guys, when you heat your plastic in the microwave, are you at full power? I'm having some yellowing and only using half power and short 1-2 minute heats until it's ready. Using stabilizer also. I think it may be yellowing after the first or second reheat in the microwave so I'm wondering if it's better to get it to temp the first time in the microwave then leave it on a hot plate until you've used it all?? If so, if it's on a hot plate, what temp are you setting it at and are you having to stir it all the time??
