I have ironed the wax off onto kitchen towels and then washed. Big stain that was still a bit crunchy. On the advice of the internet they recommended pouring boiling water on it to get rid of the rest of the wax and then running a washing up liquid into it and washing. Did that, its no longer crunchy at all but still have a big grease mark on it.
I'm assuming I'm going to have to bin it but before I do has anyone got any other tips I would try.
Thank you!
