I I've been cleaning my truck while working at a truck wash and was wondering what everyone uses or does to clean there exhaust tips. Where I work we use comet to clean smoke stacks and chrome pipes. Any ideas? Mine are pretty dirty

 

Eagle One Never Dull and elbow grease.

 

I'd suggest Barkeepers Friend. It contains oxalic acid which is non-abrasive.

I think it will do just as good of a job as Comet or Ajax and you won't have to worry about scratching the surface.

I've used it on chrome, stainless steel, etc. and it does a great job.

 

I used sandpaper, then paint, now just water.

 

Fine steel wool, then a 2 coats of wax
