Cleaning grease off of stainless steel

I don’t know about you… but my tea kettle is nasty!  It has that grease spattered buildup of years of sitting next to me cooking.  On pinterest I read that you can use Cream of Tartar to clean it.  I was skeptical since I have scrubbed it with dish soap many times without a dent… but it was worth a try.

You just wet a sponge, use make a paste with the Cream of Tartar, and scrub.  Wow!  It worked great!  You can see the difference below.

Here is my clean kettle!  It looks like new :)  And to think…. I was going to buy a new one.
