It can happen accidentally in an instant: you're carrying in the groceries and the bag bursts open, spilling your eggs onto the concrete. It might happen deliberately if someone dislikes you or wants to play a joke on you by "egging" your property. Either way, eggs can leave stubborn stains on concrete. Thankfully, there is an easy, inexpensive way to get rid of them.
Getting an Egg Stain Off Your Concrete
Clean up any leftover egg shell, white or yolk by wiping it up with a rag or paper towels.
Pour regular cola over the entire stained area. Use enough cola to cover the area liberally.
Allow the cola to soak into the concrete for 30 minutes to an hour.
Scrub the stain with a stiff-bristled scrub brush.
Rinse off the area with clean water.
