Natural Silver cleaner?

So I have a couple necklaces that I have worn all summer, through sweat, blood and tears.  Well really mostly sweat...One is a fabulous little wishbone necklace that my sweet honey gave me several summers ago.  We were up in Ogunquit, Maine for the summer and he bought this cute silver necklace for me just because.  And I RARELY take it off...the other necklace is a long funky chain with a rustic crystal pendant that I bought myself when I was out shopping in Birmingham, AL with my mom.  There is a really cool shop where artists sell their goodies and it very cool jewelry artist has some one of a kinds there...  And now I wear that mostly everyday too...SO...And now they are  too funky (and not in the cute way) after this summer and have turned.  I was just about to go out and by some silver cleaner but I really didn't want all those chemicals especially since I wear these little babies everyday.  So I am trying this little recipe I found on-line.  Baking soda+Salt+ Water+ Aluminum Foil+ Time. So I am giving it some time -- overnight.  I will keep you posted.  I have my fingers crossed...Say no to chemicals!  Here goes...#stayhealthy

****UPDATE Ok so I tried this twice.  Once with room temp water overnight - the results were not so great.  There was a little less tarnish on the silver but the necklaces were not clean.  I tried again by putting a kettle of water on.  This time using boiling water with the baking soda, salt and aluminum foil, I let the necklaces sit for several hours.  Better but still not sparkling clean like what I was looking for. Significantly better than the before pic...but you can see the back part of the long necklace is still not sparkling...Any tricks you know of?
