Can you or How do you clean a EGR valve on a 2003 Ford F-350 6.0L Turbo diesel? If you can clean it how do you do it and what is the best product to clean it with brand and all? I have heard brake cleaner, ether, and carb. and choke cleaner. What is the best? Is there also a specific brand that is better than another? Thank you to all who answer.
