The simplest way to clean up an oil or acrylic painting on canvas is to use a white cotton cloth soaked in a gentle soapy water; olive oil–based soap works wonders. You’ll be surprised to see how much grime comes off. Be gentle with paintings with thick impasto, as you do not want to break hardened paint. You might want to use Q-tips and work gently in crevasses.
