Works great
Absolutely fabulous! Put the powder in the tank, stirred and the next day the tank was clean. Purchased more.I have tried all other methods that people have told me, put lemon in the tank, scrubbed the tanks….. nothing worked. But this is a real winner!

This product did an excellent job removing the majority of the stains. Overnight worked.

Works great
I never thought about cleaning my tank. We’re having issues with our well and wanted to make sure that water color was not coming from the tank. It’s my surprise it was disgusting! 18 years not cleaned. I can’t believe how clean it came with this product. I highly recommend it.

Meh, thought it would work better
Cleaner now in the bottom of tank but didn’t affect the discoloration of the rest of the tank. Used two packets as instructions suggested.

Great Product
I moved into an apartment with a funky smell around the commode and couldn’t pinpoint it until I lifted up the tank lid. Oh my!! The smell about knocked me over. I was skeptical that this would work as well as it did. It made that funky tank clean as new with zero odor now. I will order more soon. It seems the water in my area has a tendency to build up with that nasty pink stuff. I highly recommend this. I only wish I had before and after pics. The ones I see here are totally legit.

Leaves a slimy film
Like others stated it doesn’t work and leaves a film! Left my tank with this brown slimy film.This pic is after a few flushes. It doesn’t go away!

It does it’s job!
The inside walls of our toilet tanks were dark brown! I let it sit over night , it cleaned all three amazingly well. I’ll order some more as I need it.

It really works and simple to do
I was skeptical but willing to give it a try. I really wish I would have taken a before and after picture. This exceeding my expectations. I’m not sure what happened in the back of my toilet tank before I bought this house but it tank was black and rusty looking inside. We do have really hard water so not sure if that has something to do with it. Anyway, this was simple to use and really worked. The inside of the tank is almost all white again. I’m sure if I did a second time, it would look brand new inside.

I *wish* I took a before-picture. I was not expecting this to work, but my tank has probably never been so clean. I was away for a month and came back to brown toilet water and a brown tank. This was super easy to use (all you have to do is pour it in and stir, leave it and it does its magic overnight). So happy I didn’t need to scrub anything. Would 100% buy again and recommend too!
