I'm having a clear out of DS's old baby stuff to sell and got his old booster seat out of the loft. It was fairly mildewy but a good scrub with Astonish Mould & Mildew remover has brought it up lovely...apart from the nylon webbing straps which are still covered in black spots.
Any ideas how to get rid of them? The straps won't detach from the seat so I can't run them through the washing machine. I'm going to make the most of the sunshine today and stick it in the garden for a bit but I think it's going to need something stronger than that...
