Bar Keepers Friend is a household cleaning product that’s been around since the late 19th century. Known for its gentle abrasiveness and effectiveness on stainless steel and other metals, it has become a go-to cleaner for kitchen and bathroom surfaces. However, as with any cleaning agent, questions about its safety—especially its potential to make you sick—arise. In this in-depth article, we’ll explore the ingredients of Bar Keepers Friend, how it’s used, and whether there are legitimate health risks associated with it.
What Is Bar Keepers Friend?
Bar Keepers Friend is a powdered cleaner that contains oxalic acid as its main active ingredient. First created in Cincinnati in the 1880s, the formula has remained relatively unchanged, earning it a reputation as a trusted, time-tested product.
Key Features of Bar Keepers Friend:
- Effective against rust, lime, and iron stains
- Commonly used on stainless steel, chrome, and porcelain surfaces
- Gentler than harsher abrasive cleaners, reducing the risk of scratching delicate surfaces
- Available in both powder form and as a pre-mixed liquid
It’s known for its ability to remove tough stains without the need for excessive scrubbing, which is why it’s a favorite among both professional chefs and homeowners.
Chemical Composition: What’s In Bar Keepers Friend?
Understanding whether Bar Keepers Friend can make you sick starts with understanding its ingredients. The primary active component is oxalic acid, a naturally occurring compound found in some plants but known to be toxic in concentrated forms.
Here are the main components found in Bar Keepers Friend:
| Ingredient | Function in the Product | Health Considerations |
|---|---|---|
| Oxalic Acid | Primary cleaning agent; helps break down stains and mineral deposits | Toxic if ingested or inhaled in concentrated form; causes kidney and respiratory issues |
| Sodium Carbonate | Alkaline agent that helps in breaking down grease and grime | Mild irritant; can affect skin and eyes |
| Silica | Acts as a mild abrasive | Low risk; can cause respiratory irritation if inhaled in large amounts |
These ingredients make Bar Keepers Friend effective but require careful handling.
How Is It Used?
Bar Keepers Friend is usually mixed with water to form a paste. The paste is applied to a surface with a sponge or cloth and then rinsed off thoroughly. For tougher stains, allowing the paste to sit on the stain for a brief period can help dissolve the grime.
Mixing and Application
- Use clean water and a small dish to mix a small amount of powder with water
- Stir until you get a paste
- Apply the paste to the target surface with a sponge or microfiber cloth
- Scrub gently
- Rinse completely with water
It’s important to use the proper amount to avoid leaving behind chemical residues.
Surfaces Safe to Use On
Bar Keepers Friend is generally safe to use on:
- Stainless steel appliances and sinks
- Chrome fixtures
- Copper and brass (with care to polish afterward)
- Porcelain and ceramic tiles
- Glass surfaces (avoid non-tempered glass and delicate surfaces)
Avoid using it on aluminum, natural stone (like marble or granite), or painted surfaces. These materials can react badly with oxalic acid, leading to staining, etching, or deterioration.
