Let me make some general remarks from what I gather. There are four types of people when it come to equipment, be it car, guitar or camera.
1. Collectors, who would take meticulous care of the equipment, going to the extend of cleaning the equipment at least once a week, to ensure that it's in tip-top condition. Collector generally don't use the equipment much, since any physical damage to the equipment would hurt the owner more than the pleasure that he/she would experience from the usage.
2. Users, who would use the equipment quite regularly, and have regular maintenance done on the equipment. User generally would not clean or keep the equipment in proper storage, until he/she deem that the equipment is dirtied or when the user think that the equipment would be neglected for the time being.
3. Professionals, or those who rely on the equipment to earn money. They use their equipment regularly, and quite intensively. Though they have the knowledge of maintenance, they usually don't have the time to maintain them, and would rather send the equipment for professional cleaning, rather than wasting time to do so themselves.
4. The clueless, who don't have any knowledge of maintenance, and won't actually know the importance of maintenance, until it's too late.
Hee~! Just my $0.02.
