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

The zep acidic toilet bowl cleaner works wonderful in getting rid of the awful toilet stains. Zep cleaner makes your toilet bowl nice and clean again. It is very easy to use.

If you have hard water or iron in your water, NOTHING is better than this product, not Iron Out, not CLR, literally nothing is better than Zep. And throw away those pumice stones, you won't need them. This is a miracle in a bottle. Squirt some on the orange stains, wait briefly, just a minute or two, and watch everything orange simply wipe away. I can't recommend this product enough!!!!

Works better than any toilet bowl cleaner I have tried. Very little scrubbing to do, which is simply fantastic!!

I have been dealing with hard water stains and stains from tank drop-ins designed to keep the bowl clean. I{ have tried many things including straight bleach and nothing worked. I was told by a friend to give this a try because he swears by it. I figured, what do I have to lose? Let me tell you something. Both of my toilet bowls look brand new. I followed the instructions, allowed an extra few minutes on the soak, and then scrubbed the bowl. Both hard water and product stains just about wiped right out. It did take a little scrubbing but not much. Less than 20 minutes, start to finish, on two toilets. This is the best money I have spent on a cleaning product. Actually, on any cleaning product. The smell is not an overpowering chemical smell. It is ok, almost pleasant. Quick, easy, and it works. What more can I tell you?

This is an outstanding product. I used on a heavily calcium-stained toilet. Waited 5 minutes and the calcium stains melted right off with minimal brushing. Works as advertised. I can highly recommend.

It does a good job of eliminating the base crud of the inner toilet bowl but nothing to eliminate the hard water stain around the middle of the bowl.

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! ♥

Best toilet bowl cleaner for hard water! We have well water and this is the only cleaner that will clean my toilets.
