A very dear friend of mine has been in the cleaning business for a couple of decades. She tells me stories all the time about some houses she cleans. She is always amazed at the women that clean their house before she gets there. Seems silly, doesnt it?
She recommends that personal belongings be put away, ie, mail, filled shopping bags, etc. She will do the rest.
And remember...work WITH the woman cleaning your house...eventually, she will come to know you and your family. Last, but not least, these are people. Like my good friend, whom I love, she is just as good of a person as the people whose house she is cleaning. They deserve just as much respect as you would give your doctor, accountant, etc.
