After I added the "ventilation ports" to my car cover after not giving the pipes enough time to cool I tried several methods to clean them. I ended up using 0000 (4-0) steel wool and a liquid metal/chrome cleaner. My side pipes are bright silver cereamic coated.
Since then I've tried several other methods/cleaners but have always returned to the steel wool and liquid combination for stains. Especially effective after a run in the rain when every bit of road gunk that gets splashed on them gets instantly cooked onto the pipes. After 14000 miles in two seasons the pipes still shine after cleaning. The cereamic coating is extremely hard and durable.
Conventional polish for shining them but for stains and baked on stuff the wool comes out.
