Exhaust TLC - Coke habit

My engine has been running rich for some time which has led to the exhausts becoming seriously coked up. Following a good service and oxygen sensor replacement I’m hoping that the expensive addiction is over but not sure how to tackle the mess that’s been left.

Used some Autosol today on the outside which did a reasonable job but immediately inside the tips - which is a very visible spot on the Brera, even more so thanks to the shape of the S exhausts, I’d like to try and smarten it up. The pics below really don’t show the thick rough buildup inside - it looks really quite bad.

A little nervous of causing damage with abrasive products/steel wool.

Any tips on what products/applicators and best method?

Saw this the other day, looks like it might be some help, got some funny drill attachments for polishing

Thanks, I watched that earlier on - if my exhausts can end up how his are when ‘dirty’ I’d be quite happy!

Will give the brush and wheel cleaner a go.
