We have been using Mr. Clean every other week for almost 4 years. We have always found them to be trustworthy and respectful. They have always proved to be dependable, and the work is done well. They have always been able to accommodate any schedule changes or special cleaning requirements we had. We gave them a key to the house, as well as an alarm code so they could come on days that we are not available to be home. They have been doing that for years now, and we have never had any problems related to leaving them alone in our home.
