An eggshell finish paint is not as shiny as semi-gloss, but has a bit more shine than flat. Often chosen by homeowners for its ease to clean, washing eggshell finish walls is task that doesn't involve much effort. Whether your two-year-old has left dirty fingerprints all over the walls or the walls are just looking a bit dingy and in need of a cleaning, washing the walls can be done quickly without disturbing the paint itself.
Fill a bucket with one gallon of warm water. Add 1 cup white vinegar and mix it up well.
Dip a soft cloth or sponge into the cleaning solution. Wring the cloth or sponge out well.
Wash the walls starting at the top and working your way down to the bottom. It's not necessary to scrub hard when cleaning the walls; minimal pressure is required except for any stubborn spots. Rinse and wring out the rag or sponge often while cleaning.
Let the walls air dry after washing.
