Having googled this problem, it seems that it's quite common but no-one
seems to know the answer. Can anyone here enlighten me at all?

If you can find something relatively unimportant (like a white hanky)
or something which will withstand bleach such as a teatowel or a white
towel try putting the item in a bleach solution for an hour or so -
does the stain change colour or reduce?


I've been noticing for some time, that flannels seem to develop yellow
spots even when bleached. Don't know why: its as if there is a phantom
turmeric source somewhere in the house!

S Oh yeah, that happens too - and on towels, but that's a different
problem entirely. Different colour yellow and different shaped 'spots'.
Almost like some sort of bleach marks, that one!


As Frank Erskin says above, it may be your water supply, but not just at the
water company's end. If you still have an iron pipe between your house and
the road it may be this that is gradually rotting. If it gets very bad you
will start to hear a hissing noise when the pipe starts to leak (That's how
they detect people defying hose pipe bans.). In our road the pipes all went
within a fairly short period - as they would all have been installed at the
same time - so ask your neighbours if they are having similar problems or if
any have had to have their supply pipes replaced recently.
