Home bakers and pastry chefs waste ingredients due to uncertainty about egg wash shelf life and food safety

Professional and amateur bakers frequently prepare egg wash for glazing but lack clear guidance on how long it stays safe to use, leading to either wasteful discarding of perfectly good batches or risky food safety practices. Current solutions are fragmented across cooking forums with inconsistent advice, forcing users to make guesses that result in either ingredient waste or potential contamination risks. This creates friction in meal prep workflows and increases costs for small bakeries and home-based baking businesses.
