The simplest way to clean the toilet tank is to use citric acid powder (yes it is also a cooking ingredient) and warm water. Do NOT use hot boiling water. It will crack porcelain. Turn off supply water. Flush. Pour a cup of citric acid powder. Pour warm water to fill the tank. Wait an hour. It will clean the tank amd repeat twice if there are tough stains. This cleans but doesn't prevent like the product mentioned here.

Pipes? No. Could be tough on the flapper though. Most flappers don't like bleach so this is probably better than using the blue cleaner tablets.

It's a deal but this is just citric acid and "stuff". Cheaper than and smells less than a couple gallons of vinegar. This will get rid of scale but not rust. Use "iron out" for rust.

This product is unnecessary in any home I've ever been in, and might be even harmful to the tank components. Your gaskets and seals inside the tank will need to be replaced eventually anyway, the flapper and fill valve, clean the tank out when you do that.

Whatever deposits can build up in a tank usually get flushed out anyway.

If you need, you're using the wrong bowl.

I've found it useful every few years, as there tends to be a bit of mildew that collects around the evaporation ring and some film that accumulates on the hardware in the tank.

This is a good price for this unless one has a larger need for citric acid and buys it in bulk.

Septic aside, it's not necessary. Your toilet manufacturer probably says not to use it.

What is with the pill bottle packaging? This is like the Fubuloso that comes in juice jugs

But what if house guests look in my tank? I have a reputation to uphold.
