It is always a great idea to do a major clean up at least once a year. I think before the end of the year is always a great time, so you see the New Year in with a clean home. Depending on where you live this is called Spring Cleaning.
Major cleaning means going beyond the normal weekly stuff or for those of you, like me, fortnightly stuff. Cleaning is not one of my favourite activities and I avoid it as much as I can. But saying that, I do make the effort to do a yearly clean and this involves, windows, curtains, light fittings and cleaning out those stuff piled cupboards.
So, even if it is only once a year, try and take the time to give your home a good old fashion clean it really does make you feel better.
