Customer Reviews for Instant Power 1 lb. Toilet Tank Cleaner

It did a great job on my downstairs bathroom toilet tank. I expect it to perform just as well with my upstairs bathroom toilet tank.

Great product that works!

Been using this product for years. Cleaned toilet tanks in two homes then used it for maintenance on a regular basis. Amazing results for something that’s not harmful to our home and the environment and is reasonably priced.

I did not notice any difference after I used it.

Worked very well, slight odor which may be unpleasant to some, but can be mitigated via use of fans, opening windows, etc.

Poured 1/2 container into tank, left it overnight and results were impressive, scrubbed tank walls with a old dish grunge, flushed, repeated, and the tank was amazingly clean. While there are any number of products for the bowl this is one of the very few specific for the tank and due to hard water leaving calcium and lime I really needed it, best $5 you can spend for the results.

This product is a dream & does a superb job!!

Did not clean sides without scrubbing

Worked great. Amazing. An hour later and the toilet tanks were clean.

I don’t know that I needed to use the hole box one time

Worked great!!d I’m buying some more and will use quarterly.

It took care of the problem.

Did not clean as expected

I was skeptical about this product working because it was inexpensive. However it went above and beyond. Enough for both my bathroom toilet tanks and they are both clean and look brand new. IT WORKS!!

I was skeptical that this would work and it knocked my socks off. What a great product. I would not hesitate to buy this again.
