My wife's toilet is a bit sluggish requiring the occasional use of a
plunger. It is an American Standard, 20 years old. Could someone point
me to a "how to" article on this subject or offer suggestions. I am
hoping that a Drano like product can be used.

Does it every flush properly? Mine was always sluggish; I pulled it and
found a pill vial stuck in the trap.

I wouldn't pour hydochloric acid in my toilet without something more
authoritative than a post here. I can't picture sediment building up, and I
don't know what HCl will do to your plumbing.
