What’s the best exhaust system cleaner

Exhaust system bad gunked up from a running rich and Fuel dripping from tailpipe. Any recommendations on best way to clean it? Is there there any snake oil that actually works?

 

Scotty Kilmer has stuff on YouTube for this

I’d say live with it

 

I’ll check it out. Thanks a lot for the reply.

 

409 works great on exhaust soot.

 

Sounds good probably try that. Thanks for the reply. YouTube is Kilmer shows CR 505 real expensive stuff though

 

Learned it from a tractor forum lol. Works surprisingly well with minimal scrubbing. Let it soak and do it’s job before getting after it with the scrub brush
