Zep Acidic Toilet Bowl Cleaner - 32 oz (Case of 4) - ZUATBC324 - Experience the Ultimate Cleaning Power with Our 2x Thicker Clinging Formula, Designed to Deliver a Professional-Quality Clean

I’ve had a very bad, dark mud colored hard water stain all over the inside of the toilet bowl for at least 30 years and no amount of scrubbing or other products such as using a pumice stone could remove it. I even asked a plumber who came to the house what could work to clean it and he said the best thing to do was to get a new toilet, or just live with it, as NOTHING would remove those bad stains that have been set for all these years, they were caked on the inside for good. I followed the advice of another buyer I read here in the reviews to double the amount of Zep I poured in and let that stand about 15 minutes before scrubbing. Three times I put it in the water; the fourth time I plunged most the water out of the bottom and though it took a whole lot of scrubbing with a toilet brush, I've gotten I would say 97% of that stain removed and the toilet bowl is bright and shiny and WHITE inside now! I’ve used a whole bottle and I plan to start again next week with another new bottle on that remaining 3% which is at the bottom hole and I think I will get all of it removed, just a little in that area is left to work on. I just wanted to say, and I hope all of this will let you know, Zep really REALLY works and I highly recommend it: if it got this what seemed totally hopeless toilet to look very clean it will work for you too! ♥

Just received this today and used it right away. I must say, this product worked as described. I've had a ring in my toilet bowl for a while and have cleaned it regularly but to no avail. The products that I have been using are brand names and should have worked but did not, no matter how long I would leave them on or how much I scrubbed. The ZEP worked the first time with minimum scrubbing. I use it with a toilet mop (jonny mop) because unlike a brush, a toilet mop does not fling the cleaner back at you. I will be using this product from now on. I highly recommend Zep acidic toilet bowl cleaner. Just keep in mind, it contains a strong acid, so be careful, wash your hands afterwards.

The only one that works! Oh ok, was my reply when my four year old grandson told me my pipe at the very bottom of my toilet bowl was dirty!!!!!!! Just could not find a product that cut thru all the hard water stains. But after he said that i immediately went to the hardware store and finally decided to try yet another one. Lo and behold, it worked like a charm!!!!! Now i know that i will never switch because i love this product. It does an amazing job. Grandsons always tell the truth!!! So now i will be ordering this four pack on a regular basis.

I had a badly stained toilet that had also been scratched from using a plumbing snake to remove a clog I.e., it is no longer smooth. I applied it and scrubbed the bowl per the instructions and it did a good job, much better than the LYSOL version I tried previously. I thought I could do better so I re-applied it, waited for about 20 minutes this time and scrubbed again. That time it did an excellent job. I applied a little more just above the stain and left it. Even if it can’t remove the rest of the stain on the roughened porcelain, I will be very happy with its performance and I will buy again.

I’m a rental property cleaner, and we had this one toilet that was stubborn—like, it laughed in the face of every cleaning trick we threw at it! Bleach? Pfft. Every potion and scrub in the book? Nope. We were this close to tossing it out when someone whispered about this magical stuff. I was skeptical—c’mon, I’ve tried everything! But I followed the directions, added a little extra flair for good measure, and let it chill for 10-20 minutes. One swipe with the brush, and poof—those stains vanished like they owed me money! That toilet’s sparkling so bright inside, it’s practically winking at me now!

Worked welk but not quite as advertized. Works eell enough to make it a good purchase.

This is the best toilet cleaner. We have hard water and this cleans the toilets better than anything ekes I’ve tried. It has a decent smell and is a good price for how well it works.

We have a well with hard water. This is the only product that ensures that our toilet are not yellow. Previously we were constantly cleaning our toilets and now we can go at least a week without cleaning them.
