So on that other Guzzi forum someone said an easy way to clean SS exhaust is using toilet bowl cleaner that has 10% hydrochloric acid. Wipe or spray on, let sit for 5 min. and hose off. Some light buffing to finish. There was hand wringing and pearl clutching. A chemistry expert said he would never use anything like that. So I recently got an old sporti with cruddy headers, and I ain't scared of no acid. So sprayed it on, let it sit, hosed it off, and I'm your uncle.[You must be registered and logged in to see this image.]

Wow great result Bod. Was the result just spraying and wiping or was some buffing involved? Cheers.

Light buffing, I have a old bench grinder with a buffing wheel. Used black and then white compound, maybe 10 min/ pipe.

I’ve had good experiences with the Autosol products too. Used their Metal Life Saver liquid quite a few times. Very little rubbing required, but residue must be rinsed off with water after you’re finished, as there is hydrochloric acid in the mix. I then use a liquid polish to finish it off.
