I'm not sure if it's the way I was brought up, or if I was simply made this way, but for my entire adult life I have always kept a very clean home. Some may argue that the reason my home is so clean is because I work from home and my kids are older. However, when I was working a full-time job outside of the home and my kids were babies and toddlers, my home was still clean. I honestly don't know any other way to live. And before you go thinking that all I ever do is clean, I assure you that I probably spend less time cleaning my home than most people, simply because I am in the habit of doing it every single day and it takes very little time.
I don't believe there are "secrets" to a clean home, instead I believe there are simply clean home habits.
