You have options when it comes to updating an old, ugly RV refrigerator, but the simplest fix is a coat of paint. Start by cleaning the fridge with warm, soapy water and scrubbing off any greasy or sticky residue. Then, lightly sand to create a roughed-up surface for the paint to stick to. Use painter’s tape to make sure you only get paint in the areas you intend to, and protect your floor with a drop cloth.  The key to painting a refrigerator is a good coat of primer. Use a primer that’s meant for the surface you’re painting and for the type of paint you’re using. Allow time for the primer to fully dry before you start your first coat of color.  You can also use removable wallpaper, contact paper, or even washi tape to update and highlight the appliance. Or, if you want to keep your fridge more subtle, paint or cover it in the same color as the kitchen cabinets.
