Bar Keepers Friend and Comet are two powerful cleaning brands aimed at tackling the toughest messes in your home. They both have a solid variety of products and are effective cleaners. So, what’s the difference between them?

Bar Keepers Friend

Bar Keepers Friend began in 1882 when a chemist by the name of George William Hoffman realized that oxalic acid works wonders at removing tarnish, rough, and other tough messes. He used this as the main ingredient in a cleaning powder and marketed it to tavern owners, which is where the name Bar Keepers Friend came from.

Bar Keepers Friend was purchased by Dr. SerVaas in 1956, and the company has remained in his family ever since. They worked to keep their products simple but effective and have grown to expand their line of products ever since.
