Is it definitely lint and not dark flaky bits? Sometimes washing machines benefit from an empty boil wash as it cleanses the machine of debris and dried soap powder which can manifest as dark flaky bits on clothing.
I always turn all clothes inside-out / outside-in before washing them - seem to get less fluffy lint bits sticking to them if you do this - I don't know why, but it seems to work.
Is it definitely fluff/lint and not powder bloom?
On a side not as you do liquid and hence no bleach do you find that your door seal looks grubby?
Mine is and I use liquid.
Any way to get rid? Apart from scrubbing?
Powder bloom is where the washing powder is left on the clothes after the wash, more noticeable on dark items.
As you use liquid this won't be the case.
