I have been using a product to clean my chain and de-reailers called CRC. It is a marine lubricant and seems to take a good bit of the gunk off. I generally will use a rag soaked in the CRC to get in between gears etc.
Anyone else have a good product they like. I am really looking for something I can spray on my back sprocket and then hose it off.
PS. I have to protect against the saltwater so I am going over my bike once a week.
