Mercedes 280SL and 300SEL 6.3 Engine Aluminum Cleaning Results

Both these engines had very dirty and heavily oxidized aluminum valve covers and intake manifolds. Many were tried but there were no products found that just "washed" off all the staining and corrosion.
Kent spent about 50 hours trying all kinds of cleaners, acids and brews to get these engine parts clean. Remember these are VERY old rough cast aluminum parts. They DO NOT clean up like smooth aluminum parts!
