Zep Acidic Toilet Bowl Cleaner - 32 oz (Case of 4)

This cleaner is fabulous! I have hard water…rust, limestone. I’ve used bleach, scrubbed with cleanser, and even used Iron Out, but nothing worked, and with the Iron Out I got a crust in my toilet bowl. Zep cleaned the crust, got rid of rust, and left a nice smell and a pale blue color in my water. I just bought 4 more bottles! I had a stroke so can only use my right arm/hand, and Zep makes cleaning my toilet bowl a breeze! Very effective cleaner…love it!

I would absolutely buy this again if I ran out of this. It cleans my toilet effectively well and was easy to use when following instructions. I was recommended to this product after researching of ways to effectively clean my toilet. I often use this whenever I need to clean my bathroom and this product was able to keep my toilet cleaned for days after using this product.

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.

This stuff is awesome. It took aCouple applications, but man, the ol’ toilet bowl looks brand new. Highly recommend!

Love this stuff! I forget where I heard about it, but it cleans toilets like nobodies business! It is an acid, so gotta be careful, but if you're lazy like me and don't like to scrub till the cows come home, this is great! I also used it off label to clean my shower stall. Worked, but i think you need extra caution while doing that.

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! ♥

beats anything ZEP has, thus far, produced.
