Bar Keepers Friend Spray and Foam Cleaner vs Lysol Power Foaming Bathroom Cleaner

Buy the Lysol Power Foaming Bathroom Cleaner if you want a disinfectant that kills 99.9% of bathroom germs and sanitizes in 30 seconds. Buy the Bar Keepers Friend Spray and Foam if your problem is rust stains, mineral deposits or tarnish on stainless steel, aluminum, brass, ceramic or porcelain. Lysol has the far larger review base and a proven bathroom germ-kill claim; Bar Keepers Friend is the acid-based stain remover, not a disinfectant. Both rate 4.7 out of 5.

  • Choose the Bar Keepers Friend if you are fighting rust stains, hard-water mineral deposits or tarnish on metal, tile, porcelain or glass and do not need a disinfectant.
  • Choose the Lysol Power Foamer if you want to sanitize and disinfect bathroom surfaces and cut soap scum and limescale in one step.

What reviewers say

Bar Keepers Friend Spray and Foam Cleaner

  • 4.7 / 5113 ratings

Rated 4.7 out of 5 from 113 ratings, buyers mostly report it does what the powder does in a more convenient spray. Rust and hard-water stains on sinks, tubs and shower glass come up with little scrubbing. Complaints center on the acid smell and on surfaces that need rinsing afterward.

What people mention
  • Stain removalPraisedBuyers say rust and hard-water stains come off sinks, tubs and glass with minimal scrubbing.
  • Spray designPraisedThe upside-down spray and clinging foam make overhead and vertical surfaces easier to treat.
  • SmellMixedSome find the citrus scent pleasant; others say the acid smell lingers.
  • ResidueCriticisedSeveral note a film left behind that needs a rinse.

Lysol Power Foaming Bathroom Cleaner

  • 4.7 / 53,762 ratings

Owners rate it highly and describe a thick foam that stays on shower walls and cuts everyday soap scum with little scrubbing. Complaints center on the aerosol format, the lingering scent and heavy buildup that still needs elbow grease.

What people mention
  • Foam clingPraisedOwners like that the foam stays on vertical tile and shower doors instead of dripping off.
  • Soap scum removalMixedIt handles routine film well, but thick or old soap scum still needs scrubbing.
  • ScentMixedMany like the fresh smell; others find it strong and slow to fade in small bathrooms.
  • Aerosol formatCriticised

Questions and answers

Which is better for rust stains in a sink or toilet?
Bar Keepers Friend. Its oxalic and citric acid formula is made for rust stains and mineral deposits, and the foam mode clings to toilet bowls and vertical surfaces. Lysol targets soap scum and germs, not rust.
Which one should I use on bathroom germs?
Lysol. It kills 99.9% of bathroom viruses and bacteria and sanitizes in 30 seconds. Bar Keepers Friend makes no disinfecting claim, so it cleans stains but does not sanitize.
Can I use Bar Keepers Friend on stainless steel and aluminum?
Yes. It is listed for stainless steel, aluminum, brass, ceramic, porcelain and glass. Lysol's foamer is aimed at ceramic, tile, tubs and shower surfaces, so keep it off bare aluminum and brass.
Is Lysol safe on shower doors and tile?
Yes. It is made for shower doors, bathtubs, tiles, countertops, floors and sinks, and it cuts soap scum and limescale. It is bleach-free.
Is the Bar Keepers Friend worth stepping up to if I already own Lysol?
Only if you have rust, tarnish or hard-water deposits Lysol will not lift. For routine bathroom sanitizing, Lysol covers it; the two solve different problems and work well as a pair.
Which lasts longer per bottle?
Lysol holds more product, 32 fl oz against 25.4 fl oz, and its foam covers large bathroom surfaces. Bar Keepers Friend is used in smaller targeted doses on stains, so a bottle can stretch far.
