Customer Reviews for Instant Power 1 lb. Toilet Tank Cleaner

It worked ok.....was not impressed.

I tried it. Did good job. Still looking for something that "lasts". Any ideas?

we used old toothbrush to get top turned out white!

Does not work as advertised.

Simple to use. Five stars. Removed two decades of stain/hardness. Recommend withdrawing about quart of tank water after the temperature stabilized at room temperature and restoring water with hot water from sink faucet to speed reaction removing hardness.

Slow as molasses on line service back to my local Home Depot Pittsfield. Super nice folks here dealing with it.

Unused it once on one toilet tank and it worked well. The next time I used it for another toilet tank in my home twice and both times it didn’t work.

It kind of worked. I had to add citric acid to have the tank really clean.

Worked as advertised . Poured the product into the tank per directions. Let it sit overnight & by morning all the mineral deposits were gone.

Product is really good and clean the tank in nearly 6 to 8 hours. Tank looks like new after cleaning

easy to do ,worked as advertized

This worked very well I haven't cleaned the inside of the toilet since I moved here 5 years ago

Worked well. One tip: pour some water into the tank before using to raise the water level above the normal water line. That will avoid the possibility of having a discolored line at the top of the tank.

removed all rust particles in tank

This cleaner didn't seem to help either of our 2 tanks. Seems like the instructions said to repeat if necessary and we didn't repeatedly add more cleaner. Not sure how many times one might have to repeat adding the cleaner to get any results.

This product really works according to "hype" it is awesome. Cleaned tank overnight...

Good stuff. Worked as advertised.
