1 cup ammonia
1/2 cup vinegar
1 gallon hot water
1/4 cup baking soda
Mix together and wash your walls. No rinsing is required.
We tried this on Saturday. I made half a batch and put it in spray bottles and turned the kids loose. It appears to have worked pretty well. If my paint starts peeling off in the next couple of weeks, I’ll be sure to let you know.
