I installed a Toto toilet during a reno about 8 years ago and it’s been impossible to keep it clean. The very bottom of the bowl is rough and you can’t brush it clean. I’ve tried the recommended cleaning products, draining it and using a toothbrush to clean it to no avail. There is a perpetual brown ring stain. Getting ready to renovate again—is this Toto salvageable or do I need a new one? And can I trust Toto again? Any advice?

I soak the bowl with Dawn dishwashing detergent. Seems to loosen things up. I also use a nylon bristle brush which is pretty easy on the finish.
I would definitely give it some soaking time.

I have that a similar symptom of crusty scale buildup. I can get it to dissolve with CLR after evacuating all the water out of the bowl.
I also get ok results with Muriatic Acid. But that is a dangerous chemical not for use w/o major knowledge of chemical handling and protection.
But the scale comes back.
I have a different Toto back to back with that one than never develops scale. And an Am. Std. one that never develops scale.
I think that replacing is a good bet.
Many toilets available have a special finish available which can be called things like EverClean, or Cifonet and they are molecularly superior to plain porcelain, so consider that in your upgrade.
Toto as all mfrs now, has some good flushing toilets and some not so good.
MaP Testing site is the top resource for checking on good flushing, aside from Terry Love's excellent list.
The cheapest good flush around is Toto's Entrada. Best to buy from a local plumbing supply dealer.

Thanks tried this. It didn’t reduce the brown stain at all. Ready to give up.

Thanks for the great info and advice! Even with extensive cleaning I can’t get rid of this stain.This photo is after trying Dawn and then CLR and scrubbing with a toothbrush.

It’s disgusting. Will refer to your advice in getting a new toilet—won’t go with Toto.

If it might be iron, you could try a strong paste of Iron Out.

Pumie brand pumice stick may be what works. I understand that you are not supposed to use that on the Sanigloss, but I have -- after trying an assortment of chemicals.
