As you surf the internet, your web browser keeps a record of the sites you visit and caches a great deal of information in cookies. Over time this data collection can accumulate to a point that these types of data storage start to occupy a lot of disk space, not only wasting valuable megabytes but also slowing down your Mac.
In addition to this, the cookies and browsing history that is retained can reveal a great deal of information about you and you may not want it to be accessible to other people who use your computer. Using Washing Machine you can quickly and easily wipe out bookmarks, caches, cookies, download history and browsing history.
While the program is designed primarily for use with a web browser, and it supports all popular browsers, there are other programs that track usage information about you. Washing Machine can also be used to cleanup your iTunes playlist update caches and much more.
Manually deleting the information that is stored about you is possible, but this can be a lengthy and taxing process. Washing Machine can do all of the hard work for you enabling you to cleanup certain items on a schedule and create Smart Cleanlists to wipe out information that meets certain criteria.
