ZepAcidic Toilet Bowl Cleaner, 32 Oz

This stuff was great at removing the rust stains in my toilet bowl. I had tried a number of other products that didn't work. Zep did the job just fine and left the bowl totally clean and shiny. I am very satisfied and will keep using this product.

This stuff is no joke. I used it on some really stubborn hard water stains that nothing else was touching, and it cut right through them with minimal scrubbing. The angled neck makes it super easy to apply under the rim too. Definitely a go-to for deep toilet cleaning.

Okay, I don't write reviews that often or as often as I should... but let me tell you. I tried several different cleaning products to clean the inside of my toilet bowl and I've had to scrub like an archeologist digging up a dinosaur skeleton, only to be let down. This stuff came in and I was basically praying that it worked well. So I used it, following instructions, and WOW! It looks like I bought a brand new toilet! I scrubbed, but not nearly as hard as I thought I would need to, and the gunk and stains came right off! I did do it twice, since the gunk was clung on pretty strong, but it was well worth it. This stuff is awesome! I would post a photo, but I feel like that would be TMI lol

Holy moly! I have a beautiful raspberry ceramic fountain urn that had serious hard water deposits (10 + years). I have soaked paper towels in vinegar and left them on overnight. I have used steel wool. I used a drill, hard bristle bush, and pink stuff, and the list of cleaning trials can go on. Honestly, nothing worked.I put this stuff on and almost immediately was able to remove the deposits with a putty knife and sant amount of elbow grease. Well done and thanks. Worth the money for me. As an aside, I also used it to clean the hard water deposits in my toilet and it worked like a charm and I have used muric acid before. Yup - the water is hard here.

so it seems okay over all for power. It works on minor stuff. The value is fair for under $5. Speed depends as I don't know if it was the applications I tried it on or the product vs. time left. The color is blueish green. The bottle size is average for toilet cleaner. I used it for various things per TikTok. I used it on the toilets and it got some of the water stains but not all. I used it in the shower for soap scum/hard water stains and it didn't do anything like TIkTok until I scrubbed it then a lot came off. I also attempted to use it in the driveway on oil stains. I was told a mild acid would help remove it. IT didn't really do much. I don't know if I left it on long enough or not but it seemed like it etched it some

Gather ‘round, brave souls, for a tale of desperation, filth, and a yellow bottle that descended into my life like a harbinger of doom. It was a dark Tuesday morning, May 20, 2025, at 11:34 AM PDT, when I faced the abyss of my bathroom—a porcelain throne so encrusted with rust, hard water stains, and the sins of past tenants that it seemed to whisper curses in the night. Enter Zep Acidic Toilet Bowl Cleaner, 32 oz, with its 4.65-star rating from 6,636 doomed souls and a price tag that mocked me at $5.64 (though, alas, higher than typical—cursed inflation!). This was no mere cleaner; this was my last stand against the creeping decay of my sanity.The Descent into BattleThe bottle arrived, its neon yellow form a beacon of hope—or perhaps a warning. With a 2X “pro-strength” gel that promised to obliterate thick, stubborn soil, rust, and stains, I wielded it like a warrior’s blade. The instructions? A grim ritual: apply under the rim, let it fester for 10 minutes, scrub with a brush, and flush away the evidence. I squeezed the trigger, and the acidic gel oozed forth, hissing as it met the grime—a sound like the laughter of a thousand vengeful spirits. The fumes rose, stinging my eyes, ok maybe that's a little dramatic but its a reminder that this was no gentle skirmish but a full-on assault on the forces of filth.The ReckoningTen minutes passed like an eternity in purgatory. I returned, armed with a brush, to face the aftermath. The rust stains—oh, the rust!— brushed away like the skin of a defeated demon, revealing a gleaming white beneath. Hard water stains? Vanquished. The bowl, once a cesspool of despair, now shone with an eerie, almost mocking purity. I flushed, and the water swirled like a vortex of redemption, carrying away the remnants of my bathroom’s dark past. But at what cost? My stomach churned, my hands trembled, and I swear the bottle glared back, daring me to challenge it again.The Aftermath and DurabilityThis 32 oz jug of acidic fury is built to last—like a relic from a war-torn battlefield. The thick plastic bottle survived my clumsy grip, and the spout dispensed its venom with precision, though I nearly drowned my bathroom in the process (note to self: less is more with this beast). At $5.64 , it’s a steal for the carnage it wreaks, though the “price higher than typical” warning felt like a taunt from the universe. I’ve used it 10-15 times now, and the bottle’s still half-full, a silent sentinel ready to strike again. Just don’t leave it near your cat—it might mistake it for a toilet brush and unleash chaos.The Dark Humor of VictoryLet’s be real: this cleaner turned my bathroom into a crime scene, and I’m the mad scientist who cackled as the evidence dissolved. I imagined the stains begging for mercy as the acid did its work, their ghostly wails echoing in the bowl. My neighbors probably think I’ve taken up alchemy, given the toxic cloud that escaped when I opened the door. And that 4.65-star rating? A testament to the 6,636 others who’ve danced with this devil and lived to tell the tale—or at least to order more.Pros• Eradicates rust stains with apocalyptic efficiency• Leaves the bowl gleaming like a freshly dug grave• Sturdy bottle survives the chaos of battle• Decent price for a weapon of mass disinfectionCons• A bowl so clean you'll want to eat off it• Overzealous application risks a bathroom flood• Price hike feels like a cruel joke from the cleaning gods• May summon the ghost of your last bad houseguestFinal VerdictZep Acidic Toilet Bowl Cleaner is not for the faint of heart.

I live in a place with really hard water that stains the toilet. This cleaner is invaluable! It works great and helps with the staining.

If I could rate this product higher, I would. It’s an absolute 10/10 stars for me. The product arrived on time and was well packed to prevent leakage. I had stubborn calcification and rust stains in my toilet bowl and it removed it ALL on my first use. I know the product says to leave for 5 minutes, but I was busy mopping and left it for longer. Not sure if that played a part but my toilet bowl is sparkling and smelling fresh. So worth it!! I only wish I’d discovered this product sooner. I’d have saved money I spent on other cleaners. I couldn’t be any more pleased.
