Just an update on my vote of confidence for removing rust with molasses. I was about to throw away the emergency brake pullies on my 41' because I couldn't remove the shoulder bolts without damage after many soaks in rust remover and PB. I had just mixed molasses and water for another project and decided to drop the 2 EB assemblies in. Five days later, I could tap them out with very little resistance. I'll replace the shoulder bolts, but use the pullies. 7:1 mix, with agricultural liquid molasses - about 50 cents a gallon.
