I use Wenols metal polish. The red box, since the tips already have a polish to them.
I tried the wheel cleaner and didn't do much, just broke up the surface dirt.

this stuff also work on Ti tips as well.

 

Before








After






Keep in mind that "BEFORE" picture was after only 2 or 3 months of having my exhaust. Imagine the difference it would have made had I waited longer...

 

Jedi, I noticed that after English Custom Polish, the tips stayed silver much longer than when untreated. Did you notice the same?

 

yup, one more reason I love ECP.

 

Oh yeah...........they will stay the way they should.......shiny silver much, much longer with ECP.

 

Brasso. Works great

 

I find Never Dull to work great. here's a sample pic of mine. In hindsight, I shouldn't have used the flash on the camera as it throws things off a bit (does make the tips look dirtier in the first pic though!)

 

My tips are/were completely black coated. I somewhat got the black off but now the tips still have a black residue and rough look to them.

I tried wheel cleaner and then I tried rubbing and rubbing with Never Dull. They will not return to their chrome form. Is it possible to buy just new exhaust tips?

 

Yes, it is

 

I use dish washing liquid. It works great.

 

see...

 

I love the sparkling reflection off the tailpipe...it really does remind me of a dishwasher detergent commercial

 

Product called MAAS metal polish cost about $3 @ Wal-mart in the household cleaning section =) Very easy to use and results are stunning! Removed years of grime and soot to a shiny chrome finish... very little applied pressure.

 

An '04 and you've never cleaned the tips!? I can see why you'd need to use some harsh chemicals. I wash my car weekly and always clean the tips with just soap and water.
