Baranuk has seen videos online promoting steel wool. “It’s almost like a horror movie to me,” he says, because something like that can take away the finish. What about more intense products like Soft Scrub and Comet? “These are all big prohibitions,” says Hurley. Even pure vinegar can be too harsh, she says. Baranuk likes Bon Ami as a gentle but effective option, although it often goes natural with a lemon cut in half coated in salt (bonus: the spent lemon can be thrown into the layout to clean and refresh it). Bar Keepers Friend is also in my arsenal, when my stainless steel sink needs a good shine. Some manufacturers, including Kohler, offer cleaners designed for their specific sinks. Regardless of what you use, says Hurley, it’s a good idea to test it on a small spot first and not leave it on the sink for an extended period of time.
