Silk blouse grubby black collar

[StrikesMatches]

I have a lovely cream silk blouse which I've machine washed at 30 using a silk/wool liquid, as per the label, but I can't seem to get the neckline /collar clean. I think the dark grey fleece lining of my coat has rubbed and transferred onto it any ideas how I can get it clean without ruining it?

Soap and cold water. They use soap on silk to remove marks before dry cleaning so try that. Don't scrub or pull at the fabric, just go gently. Then rinse and wash the blouse as normal. Might also be worth getting your coat washed or dry cleaned to remove the loose bits or any loose dye.

Thanks, I'll try that. Would just a normal bar of soap be the right kind? I am waiting for a day to be warm enough that I don't need my portable duvet coat so that I can get it washed and dried! I'm going to avoid wearing the two together until I do though.

Yes or hand wash or even shampoo
