Powdered oxalic cleanser with a devoted following for sinks and cooktops.
Bar Keepers Friend is the household cleanser with a professional heritage: an oxalic-acid-based powder that removes rust, scale, discolouration and set-in marks from stainless steel, porcelain, ceramic and fiberglass. Every serious cleaner keeps a can in the cupboard.
This assessment is research-based from manufacturer information, chemistry and long-term user feedback; no independent laboratory testing was performed by our team.
Anyone fighting discolouration on tubs, sinks, cooktops and fixtures — the go-to for what other cleaners can't touch.
Key features we assessed
- Oxalic acid lifts many stains and discolorations
- Restores stainless, porcelain, ceramic and fiberglass
- Also polishes chrome, brass and copper
- No-bleach option to protect finish
- Cheap per clean, long lasting
Strengths
Restorative potency is the product: it returns marked-up finishes to near-new because the acid removes the stain layer rather than just rubbing surface shine.
Powder is forgiving — you control the abrasion by how much you add.
Weaknesses
It won't work on unsealed stone or marble, where acid can etch — always patch-test and read labels carefully.
It needs elbow grease; it's a scrub, not a spray.
Value
Enormous value per gram — one can performs dozens of restorations.
Alternatives worth comparing

Frequently asked questions
Is Bar Keepers Friend safe on stainless sinks?
Yes — it's the famous choice for restoring stainless sinks, faucets and cooktops.
Does it work on hard surfaces?
Absolutely — ceramics, porcelain, copper, chrome and more; read the label before each surface.
Is it safe for marble?
No — the acid formula can etch natural stone; never use it on marble, travertine or unsealed granite.
