Cistern Problem?

[Tamtoot]

Good day all,
I have recently noticed dark streaks appearing at the back of my toilet pan ( No...not what you may think.!.) - see photo attached, and would like to know, based on your knowledge, if it is the start of problems with my internal cistern components?

Thank you in advance.

No, I get these every few weeks. I squirt bleach under the rim and clean it with an old tooth brush. If I can be arsed I put some bleach in the cistern and flush.

No, not your cistern problem (although you could take the lid off and have a look) It looks more like water stains from what is in your tap water. You are lucky, when ours does it its often a darker colour, but a good toilet cleaner and a stiff brush work wonders.
Oh, don't use bleach, bleach, bleaches things (funny that) you need a proper cleaner to remove it.
