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

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.

We have a well with hard water and it was becoming impossible to keep up with the color it left our toilet bowls. We tested this product out and after just 1 use its been like night and day... bottle says use half which we did for 1 toilet but split the second half into 2 toilets and it seemed to have had the same effect. although i have not checked the actual back of the toilet to see exactly how much cleaner it is i can tell it worked by the water in the bowl being so much cleaner and not leaving discolored rings after a few days!!! will definitely be an item we use again!

Did an excellent job but had to repeat the process periodically

This toilet tank cleaner is a citric acid based cleaner (think lemons, limes, oranges), pretty safe as far as cleaners go. There is no unpleasant odors. This is NOT some causitc chemical consoction that can burn your skin or the inside of your nose. It will NOT smell up the house or damage the inside of the tank.I used one bottle to clean 3 tanks, a third of a bottle in each tank and let it work overnight, 8-9 hours. All three tanks were nearly clean as new by morning. One tank was 24 years old and never cleaned.A few spots at the bottom along some tight right angle bends were noticeably lighter, but still brown. I'm sure if I left just just as inch of water in the tank to cover these spots, added a bit of the cleaner and stired it up some now and then, or brushed these areas a bit they would come perfectly clean too. Or use the whole bottle, but that seems wasteful considerign the results I had using it on three tanks. Maybe next time I'll keep a bit of the cleaner aside to do hit the bottom of the tankls a second time. But what was left is really very minor staining.I'm really happy with the near zero labor required to get the inside of the tank and the mechanical parts no one else sees looking clean as new. I will buy this again when needed.

The way its packaged is completely inadequate considering how rancid it is. This product contains something like muriatic acid that has an unholy noxious stench. They have it packaged in a plastic bottle like you might buy vitamins or something in and that's inside a zip-loc style baggie that is not air-tight. This stuff is so loud. Make sure you use it immediately and use all of it. The day after it arrived, when i got home from work my whole house smelled like this stuff and i hadn't even opened it yet. Christ almighty! Even trace amounts of this stuff leftover is plenty enough to stink your whole house up after you use this. Dispose of the packages in an external waste bin or something.I have no idea if this will clean your toilet or not, but it will remove corrosion and mineral deposits from your copper waterblock, radiator, fittings, etc. without damaging the copper. If you follow the instructions loosely. I left the metal parts soaking in about a gallon of distilled water with half of this bottle. It smelled a lot worse than it did before i opened it, if i need to say that. Do it outside. It reeks.

This works really well. We have very hard water and the tank can get rough looking. I’ve tried those bleach tablet but they leave the bathroom smelling like bleach and don’t work near as well as this.

I live in an apartment building and my toilet is from 1974. The whole toilet tank was covered in rust inside up to the water line. I poured half of the bottle Into the tank stirred it gently and let it sit overnight. A lot of the rust was gone. The next night I poured the rest of Bottle into the tank and stirred gently And left it sit overnight. The toilet tank is now 90% Rust free! This is awesome!
