The red is not the rust i thought i would add some detail

you will have to take the crank out to do this, get a bit of fuel tube, cut it a little longer then the crank pin, fit it on the crank pin, if you slip it wont effect the pin in any way. use a small wire wheel of the dremmel, it wont take much to get it off. dont use polish, unless your willing to scrub the crank real good. polish is a corse paste, which if its not removed properly it will mix up with the fuel , and become a grinding agent. it creates wear. the wire wheel is plenty good enough, but still was the crank good.
