I know this isn't the same thing but it puts me in mind of when my daughter was little and made a huge mess in her room. She was too small to clean it but not too small to sit in a chair and watch me clean it for two hours. By the time it was done she knew not to do that again. She did do it again though when she was 12 or so. I cleaned her room for 8 hours that time and when she came home and saw it was all happy until I evicted her from the room. She slept on the couch for a month. She was allowed to point to things she wanted in her room and I went in to get them. When she was allowed back in the room she kept it spotless.
If you want to repair it make him sit and watch what it takes to do. Maybe then he will take care of it.
