Oxalic acid (wood bleach) is better for frames than Evaporust. evaporust is very expensive if youwere to need enough to cover a frame.
WD 40 and 000 steel wool is another possibility. I've used that on a few bikes with good results
they only posted the one picture, the others I have seen have vintage Campy parts, so this may be a good bike for vintage roadbike people here.
can't beat the price.
