So after succesfully derusting the clubbie grill I had a few months ago, I thought I'd give this grill a shot as the brown was really letting the rest of the outer bodys excellent condition down

.
Pulled it of and began with the CLR and green scourer sponge thingies.
~45 mins later I've done one of the smaller stacks on the left end. I counted up the rest and realised I still had 60-70 little shelfs to do and the ones i've done are still not perfect. It seems derusting the edges of the little flats takes a lot more time then the middle no matter how hard I scrub.
It's slowly working and coming up a treat, but fiddle sticks me.. is there a quicker way to do this? I'm going to be on this for hours otherwise!
