To get dried, raw eggs off a house, one can use a hose, an enzyme-based detergent or an alkaline all-purpose cleaner. Cleaning a stain from the side of the house with a hose works best on egg that hasn't dried completely, and it can help remove small pieces of eggs.
Using an enzyme-based detergent on house siding can help remove raw egg that has dried thoroughly. One teaspoon of the detergent should be combined with a cup of warm water. A brush can be used to scrub away the egg stain with the mixture. After removing the stain, the siding should be rinsed with clean water.
An alkaline all-purpose cleaner can be used for tough egg stains. The product should have a pH range from 11.5 to 12.5 to work most effectively.
