Loose dye

[Georgyporky]

I've got 6 blue tea towels that are still shedding dye after 6 hot washes.
They are otherwise good quality.
This means I can't put them in with the other towels, so it is very inefficient & expensive to save them up & wash them alone.

I've done them @ 90, with bio detergent & soda, but the colour still keeps coming.

Any ideas please?

I wouldn't be very keen on that - dyes are pretty toxic chemicals. Where did you buy them?

@LuckOfTheDrawer
I'm not sure I understand your point. Every fabric in my house - from knickers to carpets - has been dyed.

Dylan does a dye fix sachet you can run with them in (hopefully) their last separate wash.

@Firsttimecaller Thank you.
