Bon Ami Powder Cleanser

Bon Ami has been manufactured since 1886, and its enduring formula reflects the original insight that effective surface cleaning does not require chlorine bleach, synthetic fragrance, dyes, or harsh chemicals. The active ingredient is feldspar, a naturally occurring mineral abrasive that removes stuck-on residue, rust rings, soap scum, and hard water deposits through mechanical action rather than chemical reactivity. Feldspar is a mild abrasive — significantly softer than quartz or silica — which makes it safe for most surfaces including porcelain, stainless steel, cast iron, and ceramic without the scratching risk of harsher scouring powders.

The safety profile of Bon Ami is among the best of any cleanser. It contains no chlorine bleach, no phosphates, no fragrances, and no dyes. The full ingredient list is feldspar, sodium carbonate, and sodium bicarbonate — three ingredients with well-understood and benign toxicological profiles at use concentrations. Sodium carbonate (washing soda) is mildly alkaline and provides some chemical cleaning action alongside the physical abrasion. Neither ingredient poses inhalation or dermal hazards under normal use conditions, though as with any powder product, avoiding deliberate inhalation of dust is sensible.

For cleaning, wet the surface first, sprinkle a small amount of Bon Ami powder, and use a damp sponge or cloth to scrub. The powder activates with water to form a mild abrasive paste. Rinse completely after use. It is particularly effective on bathroom sinks and tubs for soap scum and hard water staining, on kitchen sinks for rust and food stains, and on stovetop surfaces for baked-on residue.

Bon Ami's limitation is that it is not a disinfectant and not effective on grease in the way that surfactant-based cleaners are. For greasy kitchen surfaces, a castile soap spray or plant-based multi-surface cleaner handles that task better. Think of Bon Ami as the right tool for abrasive scrubbing tasks — staining, mineral buildup, rust — and use a liquid cleaner for degreasing and general wiping.
