My husband and I have a stain in our porcelain kitchen sink. How can I get it out? I’ve tried baking soda and hydrogen peroxide (the baking soda didn’t fizz), a lime and coarse salt, baking soda and vinegar (apple cider as i don’t have white vinegar but it’s on the list to get), bar keepers friend spray, nothing will help. It’s either a food stain from buffalo sauce or rust from a pan that dripped. Please help a girl out!! It’s less than the size of a dime in length, and it orange/brown/rust in color.
