Thank you.
~Forney brass hand brush, small and large
~PJ1 Super Cleaner
~Shop Vac
~Razor blade scraper for gasket on block
~Hours and hours of patiently scrubbing and a few cuss words
I will clean again when tape comes off and scrub the block Iron to a final state. I had a handful of extremely dense carbon spots that I took a VERY dull flat blade screwdriver to. I would gently apply pressure to fracture those areas, then follow up with the vacuum, brush and cleaner again. There was no way they would have come off, had I not done so.
