First developed in 1882, a chemist discovered that cooking foods containing oxalic acid, like rhubarb, spinach, turnip greens, in a tarnished metal pan left the utensil clean and untarnished. He formulated a powdered cleaning product and sold it to barkeepers to polish the brass rails that surrounded the bar. The company has been in continuous operation since that time.
What Are the Ingredients in Bar Keepers Friend?
Feldspar (mild abrasive) Linear Sodium Dodecyl Benzene Sulfonate (surfactant) Oxalic Acid (rust remover)
Bar Keepers Friend is sold in several formulas, as either a powder or creamy liquid. All of the products contain the same basic ingredients but in different strengths by weight. While Bar Keepers Friend is safe to use in kitchens and bathrooms when handled properly, it is not a disinfectant. The original Cleanser is sold in a powdered formula to remove grease and grime from nonporous surfaces, and to restore a shine to uncoated stainless steel and porcelain. The Cookware Cleanser and Polish powdered formula includes more grease-cutting detergents and can be used on glass and ceramic casserole dishes, stainless steel utensils, and enamel-coated cast iron. Bar Keepers Friend Soft Cleanser is premixed with water and works well for vertical surfaces like glass shower doors. It contains less abrasive particles than the powdered formulas.
How to Use Bar Keepers Friend
Because Bar Keepers Friend contains an abrasive, powder formulas should always be used on a wet surface or made into a paste with water to prevent excessive scratches to surfaces. Simply wet the surface that is to be cleaned and sprinkle lightly with the powder. Then, gently rub the surface with a damp sponge or cloth. Apply additional powder as needed to remove grime. Rinse the product from the surface you are cleaning within one minute of application to prevent damage to the surface. Because of the strength of the ingredients, leaving the product on a surface for too long can cause discoloration, pitting, and scratches. Dry and buff the surface with a soft cloth. The Soft Cleanser can be used on a dry surface because it is already mixed with water. Follow the same steps to clean, rinse, and dry the surface.
Surfaces You Can Clean With Bar Keepers Friend
Bar Keepers Friend is recommended for cleaning nonporous surfaces. However, because it contains an abrasive, before cleaning fiberglass, plastics, anodized aluminum, coated stainless steel, or brushed metal surfaces—including appliance exteriors—test it first on a small, inconspicuous area. While Bar Keepers Friend is safe to use on some surfaces like oven interiors, it is not recommended for overall cleaning because of the difficulty of rinsing the entire space. Use it only for spot cleaning the following surfaces:
Stainless steel: countertops, cookware, sinks, appliances Aluminum: cookware, bike frames Glass: shower doors, oven doors, cookware, fireplace doors Copper: sinks, cookware Brass: figurines, hardware, musical instruments Ceramic Tile and Cookware: flooring, showers, bakeware Fiberglass: shower doors, pools, tubs Chrome: faucets, car trim Porcelain: toilets, tubs Steel: garden tools, golf clubs
Surfaces You Should Never Clean With Bar Keepers Friend
Bar Keepers Friend is ineffective when cleaning porous surfaces like wood, fabric, leather, and concrete. It can also cause damage, including scratches, pitting, and discoloration to some nonporous surfaces. Do not use Bar Keepers Friend Cleanser in any formulation on:
Gold: jewelry, decorative items Goldplate: jewelry, flatware, trim on dishes, and glassware Silverplate: flatware, dishes, and decorative items Painted surfaces: walls, hand-painted dishes Cast iron: cookware, grills, decorative items Mirrors Granite: countertops, floors Marble: floors, countertops
