I have only cleaned my laptop key board once that I can remember, maybe twice.At work I think I have cleaned 3 keyboards in 5+ years. If I do clean electrical or electronic equipment its because dust and dirt can cause them to malfunction.
I have never been one for regular cleaning of anything except my body and clothes. Dirty things do get cleaned but for practical reasons never for appearance sake alone.
I'm with Quintin Crisp on the issue of dusting " "After four years," he quipped, "you don't notice the dust." Is that the first time the "stately Homo of England" has been quoted on RW?
I have noticed that people who are constantly cleaning, disinfecting and sanitising are often the most sickly. I dont know if thats the cause of their sickliness or an attempt to combat it, either way except for a once or twice yearly cold I dont as much as get a headache if I eat, drink, sleep and excersise right.
