Toilet Tank Cleaner – Bathroom Toilet Cleaning Powder, Removes Rust and Other Minerals, No Scrubbing, 16 Oz

I don't write many reviews because I'm a busy man but THIS STUFF. OH I LOVE THIS STUFF. Just bought my first house and after a few weeks the toilet started flushing yellow and I noticed a puck in the tank had just stopped holding the buildup at bay. Tried CLR on the discoloration in the tank with some results but nothing amazing. Then threw this stuff at it and I may as well have bought the toilet yesterday. Woke up the morning after throwing this in the tank and it was entirely clean, and it didn't cost an arm and a leg either. I hope they never change the formula of this because I'm going to keep coming back for more if the hard water is prone to staining the tank again.

Update: I honestly forgot all about this product until I was cleaning out under the sink and found the second bottle I had. Which then quickly had me check the tanks to see them getting gross again so I made sure to get pictures this go around. This powder honestly had my tanks clean within like 15 minutes and all I did was dump it. If I wanted my tanks 100% clean I'd have to hand scrub along the water line but I'm not that extra. But I've attached the before and after pictures. Let me set the scene. One day, I wake up to use the restroom and notice the water is slightly brown and has something in it that looks like coffee grounds. My first thought is what the heck? Why would my husband dump coffee grounds down the toilet but he hasn't drank any in a long while, and I don't at all, so that stopped that theory. I flush whatever it is and think that's that. Wrong! This time the water is even darker so now I'm investigating. Our towns local page didn't post about any water issues so it's gotta be a me problem. Water in the sink runs clear so it's a toilet issue so that's when I looked in the tank and was greeted by black slush like mineral build-up. Yes, I also realize I should have just checked the tank first but adhd. Anyways, so since the toilet is next to the shower and we have a shower head with a hose, I decide to try and rinse it since it came off the sides of the tank when I touched it. Well, water alone didn't cut it so being the busy mom I am I let it fill back up with water and dump bleach in there. Didn't do a whole bunch even after sitting for hours so moving on to the next thing. This time I tried oxy and again letting it sit. After a few hours the bottom of the tank was clean but the sides still had residue on them and I didnt feel like scrubbing them. A quick Google search led me here and I figured why not. After all, my goal was to just dump something in and having it cleaned with chemicals vs me spending 10 minute cleaning it myself. Read the instructions and you use half a bottle and let it sit overnight. We'll, I really wish I would have gotten a before picture because this thing cleaned the whole thing and I didnt have to lift a finger. I didn't even have to wait all night, for me, it cleaned it within an hour. The only thing that's still dirty is the faint line of where the water ends. That will take 30 seconds to wipe down though since I can just take a cloth and run it along the edge, if I even want to do that. We have 2 toilets and I did the same thing with the other toilet as well and it is clean as well. That one didn't get any chemicals to try cleaning it since I wasn't going to waste product on 2 toilets if it wasn't working. But yeah, 100% recommend if you have hard water and aren't using a water softener because it's an iron and other minerals that built up. As a busy mom, I never even thought to clean my water tanks as well. Especially since I've never had to do it at my other houses. But glad I found this product and it did what I needed it to do.

I scrubbed the inside of the tank best I could before putting half bottle in and letting dry overnight. Took some of the stains out, but not completely. Put rest of the bottle in next night and let it sit til morning. It did remove some more of the staining. Stuff is fairly cheap, so not that disappointed.

Item cleaned a VERY neglected toilet of all stains and discoloration in 1 use! (Half of the bottle) I bought 2 bottles assuming it was a big job. Apparently I’ve got extra for maintenance cleans now. Smell was as expected, cleaner but not intoxicating. Using this product was super easy. Just soak over night.

Great product but the lid came off in the package and it all spilled out into the bag

It works! Might help to have some type of brush that can reach into the tank to stir it up. It only cleans the tank. Any stains in the bowl will need something else. And most importantly, tell whoever you live with you did it or they will think something is wrong.

My tanks were quite brown and having drained them before to scrub them down, I was not looking to do that again. I saw this product and was skeptical, but it is true to its claims. The next morning my tank was clean! A tiny bit of brown was at the water line so when I used the other half on my next tank I raised the water level above the line and there isn’t a trace of brown in that tank. I sent pics to so friends and recommended they try this amazing product. No odor. No effort required. Pour in, stir, and give it time. You won’t be disappointed.

Wow! This stuff works great! My toilet tank was brown. I put this in and waited several hours and now it’s nice and clean!

Cleaned the gunk build up from the back of the toilet. Follow directions and it works as stated. Has a slight smell but nothing too bad, and worth the clean toilet!

Worked for me in some extent

Parece magia, mis tanques estaban completamente sucios, negros de uña temporada que nos estuvo llegando agua sucia, no se podía limpiar tallando las paredes. Use este limpiador y en menos de dos horas ya estaban totalmente limpios, para asegurarme lo dejé el tiempo que mencionan. Totalmente recomendable, funciona

النتائج مذهلة
