You may be able to try it for some high heat cooks on a grill via a chimney starter but I would not use it in the WSM (perhaps mix it with some charcoal that has not been wet if using it on the grill). You will struggle to get the temps above 160 - 170 in the WSM if it has been wet and maintaining temperatures will be a problem. I have had some incidents in the past of Kingsford that must have gotten damp at the hardware store and it is difficult to use for low and slow cooks.
