IT Cleaning Ltd, have been cleaning and Testing Mission critical environments for 23 years. The business cleaned its first comms room on May 3rd 2002. During this 23 years we have successfully cleaned many mission critical environments. Since 2008 we have adopted ISO 14644-1 2015 class 8 plus all accessible surfaces free from settled dust , as our specification. This is currently best practice for the cleaning of Data Centres etc. “We have managed to reach this milestone, despite of recessions, banking crisis and more recently a world wide pandemic. This is a great achievement, and I would like to thank all those who have helped and all our customers for their faith, in IT Cleaning Ltd” Stephen Yates.
