Hmm, we had some bad divelys that had 'gone off'. and we just binned it. after a short while it starts to mouldy in the lid. Thats when its time to bin it. Its starts to get worse and worse, and you end up needig about 9 coats, or it goes on too thin.
....not to mention the smell.
Although, we do have the twins now, so the baby sick smell is still lingering.
