They can be wiped, you know. With a cloth. Or even an old t-shirt or pair of pants if you don’t have a cloth (and it looks like you probably don’t).
Washing machines don’t need replacing because of a bit of mildew around the rim. The cloth or old t-shirt or pants can be soaked in normal household washing up liquid, so there isn’t even a need to buy specialist washing machine door seal cleaning fluid. You can literally CLEAN IT UP YOU DIRTY MAN.
There’s no excuse for it to be in that state, basically, and if you’re trying to sell something a quick wipe usually adds at least 10% to the final sale value.
