I have a white porcelain sink and this stuff works wonders on dark marks left by pots and pans. Everytime i use this stuff my sink looks like it is brand new and in actuality it is older than me.
I got new stainless pots and pans and my husband burned them so bad they turned cooper looking. This is the only thing that got them looking brand new. I am so pleased that I went and bought three containers and use it on my sinks, bathroom showers, and anything listed on the container... It works WONDERS!!!! And is VERY affordable!
This is the only thing that will get the stains off my pots especially when i burn something!
