One of my readers left this comment on my blog: "Thanks for all the great information! Quick question, the other day I was trowing out a paper towel slathered with bacon grease from a frying pan. On my way past my brand new, $20 Craigslist bike (was brand new 20 yrs ago and stored in a basement, what a sweet deal!) I dabbed the chain twice and rear sprocket once with a lil of the grease. I thought that's dumb and wiped it off. The next day out for I ride I stopped at a park and noticed the whole works looked brand new and the oil deeply penetrated. The only information I can find is using animal grease is to be sure to use unsalted. Have you ever heard of this?" Have any of you tried this? Could it be that bacon has another use apart from being tasty? I can tell you this, I'm trying it out this Sunday after breakfast.
