context_page_description: Bar Keepers Friend is a brand of mass-produced cleaning agents. The original canned scouring powder product has been manufactured and sold since 1882. It was invented by a chemist in Indianapolis, Indiana, where it continues to be manufactured by SerVaas Laboratories. The canned product's primary active ingredient is oxalic acid. Bar Keepers Friend has various cleaning uses.
context_section_description: In 1994, Consumer Reports found Bar Keepers Friend to perform on a par with Mr. Clean for removing baked-on soil, tea stains and other pot stains, and that it was better at removing rust. While recommending Bar Keepers Friend for a variety of household cleaning uses, author Heather Solos warned that it should not be used to clean silverware, pewter or real marble.
  The product serves to make stainless steel resistant to oxidation via the process of passivation and can remove rust on stainless steel. The product can also remove small scratches from stainless steel, silver and plates.
  Uses of Bar Keepers Friend that are not noted on its label include removing hard water stains from glass and windows and removing the brown or yellow stains caused by sunscreen containing avobenzone. The product can also clean teak wood and serves to bleach it.
