I wouldn't use it even after rinsing to remove the other stuff. There's no guarantee that it's free of fertilizer.

I'd take it back for a refund also.
You don't have any nurseries around you? Home Depot? Lowes? If none of those are around, you can probably mail order it cheap since it's extremely lightweight, like from the forum owner's shop as previously mentioned.
