Customer Reviews for Instant Power 1 lb. Toilet Tank Cleaner

I have three toilet tanks and all three are clean and beautiful now that I used this stuff!

The cleaner worked very well. We will do a second cleaning in about six months to prevent a build up of mineral deposits that badly stain the inside of the toilet bowl. We were specifically looking for a product that was safe to use with septic systems.

The product worked perfectly. Will order more when needed.

I was overwhelmed with the results of the toilet tank. It is 30 years old and never in my wildest dreams did I think it would look as amazing as it does. So sorry I didn’t take a before and after photo. Don’t hesitate to buy this product

Just follow the directions s. Does exactly what it claims to, Great product

worked as advertised. half a bottle in each toilet tank, left for 8-10 hrs and tanks were clear of all rust deposits

Works as advertised!!

The product took care of the rust from hard water. Performed as advertised.

The toilet tanker cleaner was everything as advertised! Followed the directions and checked it the next day and the toilet tank was spotless! No rust at all!!!

Works as it says. Cleaned all the staining out of tank

Noticed very good improvement after using cleaner first time.

This really works. It removed all of the built up rust, lime and calcium deposits that was causing the toilet bowl to stain that couldn’t be removed by regular cleaning products. And I only used half of the bottle. I’m really glad I purchased this because I was so tired of the stained toilet. If you follow the directions this will work!

worked as advertised. Can't get better then that.

Wish i would have taken a before pic of the toilet but this stuff worked magically and cleared all the RUST stains! i have tried about 5 other products and was so pleased with this one. Price was reasonable too! TY for a great product. This is a REAL review too folks!

I followed the directions on the bottle and poured the product in the tank and left it overnight. That was the extent of the effort I put into it. The next morning I removed the lid from the tank, and it was honestly like looking into a brand new toilet tank! I would highly recommend this to anyone wanting to clean out the tank. If you can unscrew a lid and pour, you can do it too.

Worked wonders overnight! Tank looks brand new!

This toilet tank cleaner works well. We have hard well water so the tanks get a little scummy and it flows down into the bowl. If they’re real bad it takes two treatments. Then I shut off the tank and clean up whatever is left with a cloth. Usually once a year. Good stuff.

Worked as described ...

I have hard water with a lot of iron which discolors my tank. I also had some mold mixed in. Used one-half of a container overnight which cleaned everything up with no scrubbing! Love it when things actually work.

Didn't really do anything....

Works great! It does exactly what it says, couldn’t be happier
