On my vintage machines, I used a razor-blade scraping tool - the kind that can be used to remove stickers from glass, etc. Must be VERY careful as this tool uses a very sharp blade, but it did work very well. I also like the idea of preheating the gasket. That should make the job that much easier. Main recommendation is to be patient, and take your time... and scrape away, not toward, you!
