One of my Flip wraps has sprouted small black spots, I am assuming it's mould/mildew stain. I discovered it after it had been airdrying on a rack for a couple of days.
Is there anything I can do? I did a search and see people have had good results with Milton/bleach solution on stained fabric, but this is PUL and I am afraid it would damage it (as I once ruined a food-stained Airflow by attempting to clean it with Milton). The marks on the Flip wrap are visible on both sides.
If I don't attempt to clean it, will it be ok to use or is it only good for the bin?
