Well after 25K miles it looks like my tips are getting more difficult to clean. Most of the time I just wipe tem down but now I need to take a different path. Seem the heat is starting to blue the metal and leave burnt on rings . So maybe a little scotch pad will help but eventually it will become a problem. So guys without getting to personal how's your tips.

 

When I put the used XKR backbox on my XK, I used some 0000 steel wool to shine up the tips (saw that recommendation elsewhere on this forum).

 

I used a rotary sanding disc attachment for my drill followed by a rotary buffing wheel with Meguiars metal polish. Now I can simply wipe the tips when washing and they come up lovely, clean and shiny.

I keep mine blue, it looks cool.

 

When they get real sooty, I also use 0000 steel wool with a little metal polish and in about 30 seconds, they're back to bright and shiny.
