I have bad luck with Costco detergent and cars. Two years ago I had a sweet smell coming from the back of my car that turned out to be one of those big Costco laundry detergent containers having popped open and poured liquid detergent all over the back of my station wagon. Had to pay to have car detailed. Extra even, cause the battery is back there.
Unloaded my car last night and saw a smear of white stuff in the back. I thought it was potato salad. Then I got inside and saw the container of liquid dishwasher detergent which I had unloaded from the car earlier in the day and left on my counter. A large portion of the detergent was in a giant puddle on the counter and a smaller portion dripped over the side onto the floor, all having leaked from a nail sized hole in the side of the container. I’m afraid to go back out to check my car because I don’t want to have to get it detailed again.
