LM224: LM224DRG3 Performance problem

Part Number: LM224

We purchased this product from TIstore, and found dirt on the product after delivery, which looked like water stains or oil stains
Could you please help to confirm what causes it, what marks it is, and whether it will affect the performance and use
thank you
