I need to scrub down my kitchen walls and I'm not impressed cause they were only recently painted. I started baking bread and the recipes suggested putting a water bath in the bottom of oven to help get a good Crust. However, this caused brown water to run down my walls, even with the window open. I don't want to stop baking bread but I can't be cleaning my walls each time. Any tips?
