Hi, I'm getting pink bleach like marks on dark items, especially my lovely grey towels. It is completely random; may not happen for weeks and then one item in a whole wash will have a pink mark. I've googled it and the two main suggestions are using the machine after bleaching whites (never bleach whites) and getting face cleanser for acne on towels (don't have acne!).
I was using fairy non bio capsules and comfort, am now using bold 2 in 1 liquid.
Any ideas?
