I'm gonna try that evil spray stuff then go over the system with Meguiars Metal Polish which not only shines like hell but should give it a little bit of protection.
In an ideal world you should clean the exhaust system weekly, but, to be blunt, one cannot be arsed!

Regular steel pipes on mine. 2001. NEVER cleaned, painted - nothing. But we have lots of sunny days and it's only ridden in warm, fair weather months (April through October). I change oil, clean brakes, calipers, grease brearings - but CLEANING pipes I can not be bothered. Let them rot away and get new ones in 20 year time.

We have such long winters over here, and they grit the roads with salt for months, so it just eats into things.
The salt plays havoc with brake calipers as well.
