Anyone who has used Stainless Steel pots and pans would know that after repeated use, you will get rainbow stains on the bottom. Here is a kitchen knack which I have discovered online and it works pretty well for me.
Now I have a stainless steel wok from WMF which is my favourite for stir fry. Check out the bottom. It has several stains on the bottom and it looked really horrible. No amount of scrubbing will get it off.
Now here comes the trick. This is heavily endorsed by a lot of folks online. In fact, you can check out youtube for videos how to use it. It is really very popular household item. Unfortunately, I have not found it on sale anywhere in Singapore. I got it from iherb.com
And just a little bit of powder and rub in a few drops of water with a clean tissue does the trick. I'd try to go in circular motion so that the final outcome with match the grain of the stainless steel.
And viola! I am always amazed by the outcome of my wok. It has a mirror finish to it. This product works wonder on your Stainless
steel ware. And you can use it to replace those citric acid descaler for cleaning the bottoms of your kettles and milk bottles steriliser to make them look brand new again.
I have been recommending this product to so many of my friends. You should give it a try too!
