tips for getting laundry marker out of curtains

[WottaMess]

Just that really. Had a proper oh shit moment this morning when running to rescue the toddler from something holding the open laundry marker i'd been using in one hand. Brushed a lovely line over my bespoke pale linen curtains. Bollocks.

Have tried spot treatment with hairspray and a gentle dabbing with wet wipes, both of which were Google recommendations but neither of which has helped.

It's a mother are water based pen if that makes any difference.

Thanks in advance.
