WashAndGo is an application designed to maintain order in Windows XP/Vista/7/8 by removing unnecessary files and taking care of the system registry. The tool allows, among other things, to clean the system (removing unnecessary files, logs, memory shots or temporary folders), traces of the use of various applications, browser cache and much more. WashAndGo 2015 is also equipped with a number of additional tools, including a module responsible for secure deletion of data, uninstalling programs, unblocking files blocked by various processes or a visualizer showing the content of disks and folders.

The authors also thought of implementing a module allowing for quick optimization of the entire system and planning for automatic launch of the WashAndGo program.
