What sort of degreaser ! is it a polished rocker cover if so try some good car polish on it

You will probably find anything that will shift it will dull off the polish. If there is some staining in an unseen area you could try a bit of oven cleaner. I also wonder if a paste mix of bicarbonate of soda might work, also to be tested somewhere out of sight.

I've tried a couple of different ones (both good quality ones-one the yellow tin crc one and another one and industrial one) scrubbed them both in with a parts washing brush too, it actually bad a minor difference, but what i guess is the hardcore, well attached stuff remains.No, the alloy isn't polished-in fact it's relatively rough cast (which obviously doesn't help).

ally oop- you need multiclean and a NAIL brush for the rocker cover -that and a water blaster to shift it -it often takes a couple of goes

CLR would move it, perhaps followed by a quick rub with autosol. As kaz suggests a scrub with a small stiff bristle brush willhelp and it may take more than one go at it.

Degreaser is for removing grease and oil. What you need is a multi purpose cleaver.

I don't think cleaving the rust off is quite what the OP had in mind-and is a bit radical don't you think!
