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

We have very hard water and mineral build up at the water line is a problem. This product is more effective at helping to remove this and cleans very well also; better than any other product that we have tried. Toilet looks new!

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?

I chose this product because it had an industrial strength cleaning solution. It removed toilet bowl strains from the last century.(blatant exaggeration.) just let me say that these were old school stains. I squeeze it put it on the toilet bowl underneath the rims. The products lay down removing stains as a caught, and then went into the part of the bowl that goes to the sewer and clean that out too. Yes, there was a minor bit of scrubbing. I left it in the bowl overnight, even that was unnecessary.

For years, (11 to be exact) I have tried and tried to get the hard water out of my toilet and off of my shower stall with everything I could imagine, buy or concoct. I came across this on Instagram one night, gave it a shot and I'll never buy a different product for any cleaning. It made my toilet, shower stall and kitchen sink (different bottle used for each) look brand new with nearly no scrubbing. Hard water-GONE, staining-GONE, toilet ring-GONE, toilet stains-GONE! Trust me when I say, BUY THE 3 PACK!

Took a few uses but very effective for taking away hard water stains and scums. Good value for the job it does. Would recommend to those with hard water issues.

This is the best toilet cleaner ever. I have low=flow toilets that are gravity flush. There is usually a ring at the water line but the water doesn't come into the bowl from under the entire rim. It is so easy and quick. Brushing takes a few seconds. No scrubbing. I had been buying one bottle at a time. I ordered the four pack so I could put one in each of my three bathrooms. Great product.

It’s a miracle workerRenting a house last 7 yearsStain in toilet tried everything to get rid ofFive minutes of this product and stain is completely gone. Highly recommend you won’t be disappointed.

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! ♥
