your journey may vary - all i did was use undiluted simple green to clean and then got them drunk in 70% alcohol where i soaked for about 10-15 minutes or until i started to see them flake off with a light brush. Carefully not letting them sit too long to affect the label glue. Some needed a second round but i waited a day.
You can see the three stages below. Juiced - drunk - oiled.
Special kudos to Kifer for the advice
