Unpacked my suitcase and found some blue/green dye had transferred onto a few white things that must have been next to perhaps jeans in the case. I can only assume this was to do with me putting my toiletries bag, which had wet bottles and shower puff etc, in there and perhaps the damp bag facilitated the dye transfer.
The same stuff was perfectly fine in the suitcase beforehand.
Anyway, I tried removing the stains with Vanish and a run in the washing machine but to no joy.
What could I buy or what typical cleaner might remove the dye transfer please?
It's even got on my white duvet as I just chucked stuff out of the suitcase before putting it all away and I now have a blue rectangular outline on my nice duvet. 
thanks
