I'm pretty clean with food! We don't have a dishwasher, so washing the dishes is a daily duty, of at least 3 times a day. Kitchen, bathroom, laundry, catbox and garbage removal are my major have to clean places. I can't stand anything to be unsanitary.
Messy or disorganized, that is a whole different ball game as it's sanitary, but it looks like shit. I get pretty messy with my art supplies because I don't have a designated area for it in Ohio yet. But on the whole, at least from when I had all of my stuff with me in Maryland, compared to most people that sling oil paint, and charcoal, I'm pretty neat as this goes too! My palette is always clean, and the only evidence of it being well used are the scratches and marring from my palette knife. My brushes are pretty good too, no dried color on them, and the only evidence of seeing paint are the worn out brushes, and the handles are pretty paint caked and bubbled up from turpentine.
heheh, I do have a bad, bad habit of plopping newspapers, and mail on the closest available surface, and letting that accumulate.
