Cleaning up after an art project is the more boring, but necessary part of keeping all your supplies clean and ready for many future paintings. I use a plastic paint palette for all my videos, and I really enjoy using this because it is easy to clean and doesn't require me to throw it away. I am all about reusability with this one :)
I start the cleaning process by removing excess paint on my paint palette with a damp cloth/paper towel. I then rinse my plate in warm water until all the paint is removed. Simple!
