I just got my keggle back from the welder today. I am planning on giving it a good wash in BKF. Should I let the BKF rest on it for any amount of time or just scrub and rinse?
Aside from that is there anything else I should do? There are some flakes from the top being cut out that are stuck to the rim, outside the boil area, (picture follows) should I worry about getting rid of them due to rust issues?
Pictures of the welds and such:
