I replaced the entire valve assembly and the flapper.

Still, the toilet dirt lines appear, as can be viewed on the pix.

What should I do next?

Read this link carefully about using muriatic acid to clean the bowl

rim jets. Carefully if on a septic system as it requires baking soda

to neutralize the acid before a flush.



The "dirt" - slime is coming from the rim bowl jets.

Plenty of old threads in AHR about it. You could use some muriatic

acid in the bowl, brush with a nylon toilet brush, the stains will

come back sooner, unless the rim jets are cleaned.



Side view of the rim jets (flush passages), etc.

Or buy one of the rust stain removal products, like CLR,
etc that are available at hardware store, HD, etc. On
the stains like that I used it on it disappeared almost
instantly, no scrubbing, just applying it.
