According to the 2015 material safety data sheet, the ingredients are feldspar, linear sodium dodecyl benzene sulfonate (DDBSA), and oxalic acid. Unlike more abrasive cleaning powders such as Comet and Ajax, Bar Keepers Friend uses oxalic acid as its primary active ingredient. A similar abrasive cleaning product, Zud Heavy Duty Cleanser, also contains oxalic acid. Prolonged use and extended skin contact may cause irritation, peeling and contact dermatitis, which is avoided by wearing gloves. The product can also be an eye irritant.

What's the best answer to this question: is bar keepers friend the same as comet?
no
