Expecting dc2 and realised dd1s lovely playmat and the attached soft toys has some little spots like mildew on it, presumably from getting a bit damp being stored in the attic. Any way of cleaning it, and making it hygienic? The mat part has been through the washing machine machine once but some spots left. Some other bits couldn't be put in washing machine eg those that are attached to the main arches or have bells etc in them.
