Bar Keeper’s Friend is a mildly abrasive cleaning powder used to clean and polish hard surfaces. It is commonly used to remove rust, water spots, tarnish, mineral deposits and other stains.
To use Bar Keeper’s Friend, add water to the powder to form a paste and apply to the stain, then scrub with a cloth or brush. When less abrasive cleaning is required, add more water to the paste before applying to the stain. Bar Keeper's Friend does not contain bleach, making it an ideal cleaning agent for stainless steel and other hard surfaces. For tough stains, apply a thick paste of water and Bar Keeper's Friend and allow to sit for 10 minutes before scrubbing.
