What's the best way to clean this up?
UK based. I have to replace the diff rear cover bushes and want to clean up the outside. What's the best way to clean it? I see some people also paint them. Not sure if I want to paint it but if I did what paints etc. are best? My Dad used to say that with some parts the dirt and grime actually helps stop the metal deteriorating.
Another question is it a bad idea to clean out the inside yes or no? And if yes, what's the best way to clean the inside.
Thanks in advance for advice.
