Many have asked about the Dupont Chain Lube. I use it and this is a picture of a very dirty, nasty, filthy chain using the Dupont lube. As you can see it looks nothing like a conventional filthy chain. That is the beauty of the Dupont Lube, it flat out works and does not attract dirt and grime like conventional lubes. I will clean the chain next week as it will be raining again here. This Chain has 700 miles on it since the last cleaning and that includes rain and sand.
