Vance & Hines Pipe Cleaning

[Jonny is New]

I have the Big Radious 2-into-2 black pipes on my flat black 2009 Street Bob. I've been using my Harley Flat Black cleaner on my pipes, but I started seeing streaks on the pipes.

What are people using to clean these pipes?

Thank you,

Jonny/

HD sunwash & water - I don't really use anything special on my black pipes (ceramic coated) and they still look like new. Might be some of the product/residue burn-off??
