Blue what look like ink stains on clothes AFTER washing!?

[Je55ika]

Please help... I don't know what the cause could be... I've been doing washing year with no issues and then we moved last November and since then we've had trouble with blue stains appearing on our clothes.
We have moved house since and we are still getting the problem, we have also had 3 brand new (different brand) washing machines and still getting the stains. I've also completely changed all my washing products incase it was one of them and low and behold today I take the washing out and it's all stained.
Please help, its driving me mad... I feel stupid like it's my fault... And the money for new clothes is really starting to take an impact.
MANY THANKS IN ADVANCE

Is there a pen in your washing machine door seal? Has someone started a new job which means they frequently put pens in their pockets and they are not always taken out before washing?

This happened to me! I switched from using pods to using powder and that seems to have helped. I also use a bit less powder than they recommend. So frustrating, I've wrecked some lovely tops.

This happened to me. Ruined a jumper, which I'm wearing now just as a warm top before bed. No idea what it was 😖
