No, Comet and Bar Keepers Friend are not the same thing. While both products are used for cleaning purposes, they have different formulations and uses. Comet is a powdered household cleaner that contains abrasives and chemicals such as sodium carbonate, sodium dodecylbenzenesulfonate, and sodium dichloroisocyanurate. It is commonly used for cleaning surfaces like sinks, bathtubs, and toilets. Comet is known for its abrasive nature, which helps in removing tough stains and grime. On the other hand, Bar Keepers Friend is a powdered or liquid cleaner that contains oxalic acid as its active ingredient. It is often used for cleaning stainless steel, porcelain, ceramic, copper, and other metal surfaces. Bar Keepers Friend is effective in removing rust, stains, tarnish, and mineral deposits without scratching the surface.
