here's a little secret weapon on cleaning greasy stuff - Scrubbing bubbles bathroom cleanser ! works miracles.

you can replace the nipples only - not the spokes - but if the spokes are rusty they are not stainless - so you are probably into rebuilding the wheels. take a spoke out and measure the length.

Most shops are not willing to do restoration work of this type - even at shop labor rates it's not worth their time. So it's up to you. Nice project !
