Why are my Sandies pink?

[Cies]

They are coming out of the wash tinged pink, obviously where the poo and wee was strongest. I`ve now had them hanging outside for a couple of days in the light (some sun, some cloud) but if anything they're pinker than ever.

I dry pail, cold rinse cycle, wash at 40 then line dry outside or on rack over radiator.

They're cotton btw.

Any ideas?

apart from a sock lol not sure!

do you think it could have anything to do with build up? would stripping them help?

no socks, cos I only put nappies in and wash every other day.

Could be - would def strip wash and see if makes a difference - also try some laundry bleach like home scents one.
