Onan MDKAL Exhaust Elbow Replacement Part 4: Cleaning Exhaust manifold

Now looking at the exhaust manifold build up

Preparing for cleaning

Used what I had

I also used a metalic brush and various grid of sand paper (from 60 to 100)
You can already see of the carbon build up in the plastic bag

Little rush on the bolt, using a brush to clean

Looking almost like new

Note from Bill Kinney SM160 Harmonie: the lock washer should be changed as they anneal and lose their spring.

Exhaust manifold looking better
Note all the carbon residue
