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

Tried 3 1/2 gallons of vinegar as recommended on YouTube to clean the hard water stains in our toilet tanks. The toilet tanks are 10 1/2 years old. The vinegar did absolutely nothing.The tanks were brown and nasty looking even after using Clorox tablets.This product only required 1 cup and we left it overnight. The next day we were amazed to see clear water in our toilet tanks!!Amazing product of citric acid. We have already bought more. I bottle will clean 2 toilet tanks.

Worked great to remove stains and mineral deposits in our toilet tank. It removed most of the slimy stuff at the bottom of our tank. Just pour half a bottle into the tank, stir, and leave it for 12 hours.

This stuff does the job with no elbow grease required. I used half of the recommended amount and it did a surprisingly good job on my tank that has been exposed to super high iron well water for an extended time period and was very stained.The only reason for marking it off for one star is that it is not natural and it is always my preference to clean with natural substances rather than resorting to synthetic or chemical products.

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.

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.

We have 3 bathrooms and i was able to used half of it. It really removed the sticky rust,grimes inside the toilet tank. After soaking it overnight I'm amazed that the toilet tank looks like new! So I'll recommend this product very much!

I never leave reviews but this stuff was amazing! We have a well and this toilet tank hadn’t been cleaned probably ever so no telling how many years. I did a little scrubbing with a basic cleaner and then let a half bottle of this magical product sit over night. Amazing quality and stain removal with no scrubbing!

WOW I wish I had a before picture but I don’t think I expected it to work. But it does. Quickly. From Mississippi River water in the tank to crystal clear when we left sitting overnight. It takes half the jar per toilet so we took care of both bathroom toilets.
