I have been buying a lot of bulk Lego recently. I sort and clean every lot so I know to expect non-Lego and randon stuff, but this lot, by far is the worst I have seen. Not only were the bricks excessively dirty, but the lot was about 1/4 non Lego, with the majority being junk plastic and a number of sizable rocks and bolts. Also, what I fear might have been rat droppings In the bottom.
