Things You'll Need
Baking soda or borax
Bucket or large bowl
Splattered milk on a painted wall is one of those things you may not notice right away, especially if it's in a corner or on a lower part of the wall. Now that it's dry, it's tempting to scrape it off but that can actually do more harm than good. Using mild cleansers such as baking soda or borax is more effective and gentler to your painted walls than harsher cleaners.

Mix 1 cup of baking soda or borax into 1 gallon of warm water in a bucket or large bowl. Stir with your hand until dissolved.
Put a clean cloth or sponge into the bucket and let it absorb the cleaning solution.
Wring out the cloth and wash the dried milk from the painted wall using a circular motion.
Dry the wall with a clean, dry cloth. If any dried milk remains, repeat the process.
