A can of Bar Keepers Friend.

Bar Keepers Friend is a powdered cleaning product made by SerVaas Laboratories in Indianapolis, Indiana.[1] It's been produced since 1882, and was invented by a chemist in Indianapolis, where the product continues to be manufactured.[2] Trademark number 17,313 was filed on October 2, 1889 by George William Hoffman who asserted the name had been used since January, 1887.[3] It has since become the base of a line of cleaning products by SerVaas, who started producing and carrying the product under the Bar Keepers Friend name in the 1950s.

Active ingredient[edit]

Unlike some other abrasive cleaning products, 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.[4] Prolonged use and extended skin contact can cause skin peeling and contact dermatitis, avoided in prolonged use by wearing gloves.

Use and effectiveness[edit]

In 1994 Consumer Reports found Bar Keepers Friend to be on a par with Mr. Clean for removing baked-on soil, tea stains and other pot stains, and better at removing rust. While recommending Bar Keepers Friend for a variety of household cleaning uses, author Heather Solos warns that it should not be used to clean silverware, real marble, or pewter.[5]

The logo of Bar Keepers Friend represents the swinging doors of a saloon. According to the President of SerVaas Laboratories, Paul SerVaas, although some people complained during Prohibition, "the name was never changed. It's been Bar Keepers Friend since 1882."

Off label uses of Bar Keepers Friend include removing the brown or yellow stains caused by Avobenzone containing sunscreen.[6]
