TOTO Neorest 500 bowl surface no longer easy wash

[Margaret Manning]

We bought the Neorest back when it made its debut at the Kitchen & Bath Show. Nearest 500. For more than a decade, the bowl was easy to clean. In fact, it seldom needed cleaning. Over the past year, it has begun accumulating stuff AND is always developing a ring at water level. We love the Neorest but hate the fact that it always seems dirty. I doubt that we used anything damaging to clean it. Is it normal for the bowl finish to deteriorate after that m7ch time? Tempted to get a newer model.

Well?
City water?
I am not a pro. I know this is not recommended by Toto, but a Pumie pumice stick can do wonders on a ring at the water line. But if you are considering replacing the unit, try that. https://terrylove.com/forums/index.php?threads/toilet-bowl-ring.57800/

ALL porcelain tends to accumulate invisible/microscopic mineral accumulation from urine and minerals in the water.
Toto and many other mfrs make optional special finishes that keep the bowl from accumulating better, but after a handful of years, even those finishes will build up similarly.
Removing the water in the bowl and using, say, CLR and letting it soak may give you some benefit.
I've used but do not recommend muriatic acid...but minerals keep on coming back.
