I just spent a minute cleaning the surface , but not sure the pics will show up clear enough on here ?
First pic is as-found .
Second pic is after a quick rub with a brawny
Third pic is after a quick rub with a70/30 ipa/di wipe
Last pics are after a quick rub with 70 ipa and a white scotch-Brite
I plan to clean all sealing surfaces more thoroughly before bolting bits back on
