Vintage on line

I have a very bad habit of leaving the cat food cans
in the sink to soak for hours...ok, ok, over night...
ok, ok well into the next day! And since there just
might be one or two other things in the sink too
(I have mentioned before that I am a slob, right?)
those things or two, get rust spots on them.





You think I'd learn my lesson...but Pavlov's dog
I surely am not!




So, I went to the Oracle of Delphi (aka Google) to
gain the wisdom and knowledge I would need to
get these rust marks off my dishes and the best
I could find was CLR....but it didn't work.




SO, I KNOW that some of you...one of you...
must have a sure fire way to get these rust stains
out?!!



HELP!

(and thank you!)
