Bar Keepers Friend primarily relies on a combination of oxalic acid (a naturally occurring rust remover), feldspar or glass oxide (a mild abrasive/grit), and linear sodium dodecyl benzene sulfonate (a surfactant that cuts through grease).
No, Bar Keepers Friend is not baking soda.
Yes, oxalic acid is the primary active ingredient in most Bar Keepers Friend (BKF) formulas. It works in combination with a mild abrasive (like feldspar) and a surfactant to break down rust, tarnish, and mineral deposits.
Bar Keepers Friend is a powerful cleaner that works wonders on stainless steel, glass, and porcelain, but its active ingredient (oxalic acid) and abrasive nature can ruin delicate and porous surfaces. Never use it on cast iron, non-stick cookware, marble, granite, wood, leather, or painted surfaces.
But while BKF is not non-toxic (you cannot drink the stuff), it is approved for use on cookware and kitchen surfaces so long as you rinse everything well after cleaning.
The safest cleaning products for your home are those made with non-toxic, plant-based, and fragrance-free ingredients. Top commercially available safe brands include Branch Basics, Force of Nature, and Blueland. You can also use highly effective, inexpensive household staples like baking soda, castile soap, and white vinegar.
#3 Vinegar And Baking Soda
The acidic nature of vinegar helps break down grease and mineral deposits, while baking soda adds a mild abrasiveness to scrub away stains. It works on everything from bathroom, stovetops to clogged drains to burnt pots. It's highly effective and completely non-toxic.
Bar Keepers Friend is an oxalic acid-based cleaner used to dissolve rust, mineral deposits, and tarnish, making it ideal for metal and stainless steel. Ajax is a bleach-based alkaline cleanser with mild abrasives, best for whitening surfaces, cutting through everyday grease, and deodorizing.

Use it in my tub as well. Eliminates the hard water stains with very little effort." – Lois "It did the job! I live in a "hard water" area, and I use it on my toilet bowls. It does a great job and leaves a shiny bowl with a clean scent.
Those stubborn brown stains on your oven glass are usually layers of baked-on grease and carbon. You can easily lift them by creating a thick paste with 12one-half12 cup of baking soda and a little water, plus a few drops of dish soap. Spread it over the glass, let it sit for 20 minutes, then scrub and wipe clean.
Plumbers recommend cleaning toilets using distilled white vinegar for safe, natural maintenance, or commercial acidic/enzymatic cleaners for tough mineral buildup. They strictly advise avoiding harsh chemicals like drop-in bleach tablets, which can corrode internal rubber flappers and flush valves over time.
Oxalic acid is a highly corrosive and toxic organic acid, widely used as a bleaching, cleaning, and rust-removal agent. Its primary hazards include severe tissue damage upon contact, systemic toxicity if swallowed, and the potential for long-term organ damage.
Bar Keepers Friend does not have bleach, so you wouldn't have fumes like you would from a product containing bleach or ammonia.
To DIY an effective substitute for Bar Keepers Friend, combine 1 cup of baking soda, ½ cup of salt, and ½ cup of borax. Mix thoroughly and add water to create a scrubbing paste. This homemade paste breaks down grease and lifts rust from stainless steel, copper, and porcelain.

To remove stubborn yellow stains (often caused by hard water minerals, rust, or uric acid), you can use an acidic cleaner like vinegar or citric acid. Either turn off the water and empty the bowl, or cover the stain with a cleaning agent, soak for 20–30 minutes, scrub vigorously, and flush.
Abrasives to Remove Hard Water Stains
Many window cleaners prefer Bronze Wool over Steel Wool for the simple fact that it lasts longer and does not rust. Either option will work though. For milder stains, a scrubbing pad and a bit of elbow grease and buffering can go a long way!
Dish soap has the ability to lubricate and break down the bonds of fats and grease. When poured into the toilet, dish soap helps lubricate the waste causing the clog, while also breaking down its structure, allowing it to easily flow down the drain.
The healthiest all-purpose cleaners are plant-based, biodegradable, and free from synthetic fragrances, harsh solvents, and hormone disruptors. Top, rigorously vetted options include Dr. Bronner's Sal Suds, ATTITUDE Nature+Technology, and Branch Basics. For ultimate safety and savings, you can also mix your own using simple household items.
Bar Keepers Friend is a powerhouse cleaner that relies on oxalic acid and mild abrasives to cut through rust, mineral deposits, and tarnish. Depending on what you are trying to clean, you can use common household items or store-bought equivalents to achieve the same brilliant results.

Never mix Bar Keepers Friend (BKF) with bleach, ammonia, or vinegar. BKF contains oxalic acid, and combining it with these chemicals will trigger hazardous chemical reactions, releasing toxic, lung-searing fumes like chlorine gas. Always rinse surfaces thoroughly between using different cleaning products.
Both cleaners are heavy-duty, but they work differently. Bar Keepers Friend is an acidic cleaner that relies on chemical reactions (oxalic acid) and mild micro-abrasives. The Pink Stuff is an alkaline cleaner that relies primarily on heavy mechanical abrasion (quartz sand) and soap.
For easier cleans:
Wipe out the crumbs with a paper towel or rag. Wet the sponge and squeeze about five drops of dish soap directly on the sponge (scrubber side) or spray a liberal amount of Dawn Spray on the sponge. Wipe the bottom of the oven and walls. Scrub off baked-on particles.
