How should I wash butter muslin? I used butter muslin (the link is to the specific product I used as an example) to roast a turkey crown (following the method from this article). I now have a piece of muslin with a tie-die pattern of browning from where the creases were. I can get most of the butter out by rinsing it in the sink but obviously it needs proper washing before I store it and use it again.

Can I put it in the washing machine on a typical clothes-washing cycle? (Not quite on-topic, but how wary should I be of putting it in with clothes I don't want to ruin?)
Is there anything I should do after washing it to make sure it is food-safe? Is there any risk of detergent residue I need to look out for? I normally use 3-in-1 laundry capsules.
Accept that it will never look pristine white ever again.
Whatever you do, don't wash it in Persil. That stuff is designed to make your clothes bright &amp; nicely perfumed, not something you need in your turkey - &quot;seven day freshness&quot; isn't quite what they meant in the adverts. At least it doesn't have fabric conditioner in it, which would be even worse. No-one ever bought Comfort for how good it tastes;)
Unless you want to invest in some pure soap*  - flakes or liquid at various prices from reasonable eg Wilko's to truly ridiculous &quot;they saw you coming &amp; laughed&quot; then you'll be fine just washing it in regular washing-up liquid, or give it a soak in bleach first, so long as you rinse it afterwards until you can no longer smell it. [I'd just go with Fairy myself &amp; put up with the staining].
*&amp; run it through the washing machine all on its own, wasting an entire wash cycle for one cloth.
