Wait a minute here. Simple Green is an excellent product, sounds environmentally friendly too but havn't you heard of the FOSTERCLEAN method. Yup, it was developed by Sir Don Foster himself, that's the same Foster of relay soldering fame. He cleans all parts and even his driving sunglasses in the missus' dishwasher. Now that by itself was good but somehow he developed a strategy to secure her agreement to this cleaning process. What a genius!
