Haven't cleaned but minimal rust/oxidation and not sun faded. Spotted the one from down below and there was the end of another one poking out beside it.
i've found that 7 up can before but wasn't in very good condition , the white " wet and wild " can is fairly hard one to find as i don't have one in good condition yet and i have a whole bunch of 7 up cans from same era , i think it was used in the late 60's
