I usually check the lid of a detergent bottle by trying to tighten it. The one time I forgot, the bottle turned over in the car trunk and spilled. Fortunately, most of the liquid detergent ended up in the plastic bag instead of the floor of the car trunk.
I now leave a heavy duty plastic basket in the trunk to hold the groceries. I had the same thing happen with a gallon of milk some twenty years ago.
An ounce of prevention is worth a pound of cure.
