Hey Gang,

How can i get these stains off the sprocket?
Tried Kerosene, WD40 and Mucoff Cleaner. No Chance...

 

Wear them as a badge of dual sport "honor". You got them using the bike.

 

Its for selling purposes 😁. People here in Thailand want shiny and new

 

I would say the metal is stained, the oil is in the grain of the steel. You may find some kind of bleach to do the job. Maybe consider removing it so you can do some serious cleaning methods, including sand blasting, if it is worth that much. Off the bike you could even paint it black or silver. Or spend whatever it costs to buy a new one if it is worth that much in the sale.
