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 love this toilet cleaner. Since I have well water (which contains minerals), the minerals tend to form a stain in the bowl at the water line. I use this cleaner 2 to 3 times a week which prevents the ring stain from forming. This is an excellent cleaner, as are many of the Zep products. Home Depot does carry this product, but its more economical to purchase a case from Amazon than single bottles from Home Depot.

My village as municipal well water and as such the toilet rings can get atrocious, as well as a light brown/tan staining of the bowl itself no matter mow much or how often I clean them. This stuff gets the stains out and makes my bowls sparkling white and clean. Love it. Only product that works.

This stuff is amazing. Our water is so hard and I never thought I would be able to get our bowl clean again. The smell is strong but not overpowering at all. It did take a bit of scrubbing but nothing like I thought I would need to do. I was absolutely impressed. It saved me a couple hundred dollars on replacing our toilet.

This is the most wonderful product I have ever used to clean my Toliet bowl & shower. We have a well, we get rust constantly for the past 31yrs. I was so frustrated I gave this product a chance & within minutes the rust vanished!!! Now I know you may think I am lying about this product. I’m not!!! I have tried The Works, Clorox & other over the counter brands for years. I ordered a 4 pack so I’m a very happy with it. No bad smells easy to clean & leaves a shine to your Toliet. Nana/Mimi.

Listen I don’t have pictures because I’m touchy about showing you all my toilet. But let me just tell you!! This product does exactly what they say it do!! It works incredibly. Package came intact, no leakage. I couldn’t believe it worked on one usage. Instructions were easy to follow. Package was On time. Delivered in EVERY WAY POSSIBLE!

Too RUNNY, needs IMPROVED more-sticky gelatinous formula. Usually a household-cleaners price-shopper, but some commode cleaners don't sufficiently prevent/remove mineral-deposit-buildup in very hard water. Cleaners with acid do a better job. Price per ounce (as bundled) is fairly reasonable, but I do NOT like having to purchase FOUR QUARTS at a time in bundles. Do NOT like devoting so much under-sink space to a mountain of bottles every time reordered. Prefer availability as iningles. 2-packs might be OK. And distribution is somehow a pain. Claims made in USA, but takes forever to arrive at major USA city. WHY not warehoused by Amazon somewhere and readily available without delay?

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! ♥

My husband and I are in our late seventies. He was a Master Plumber for 40 years. This is the BEST toilet bowl cleaner and easy to use.
