Quick Intro

Nowadays, a lot of people are using a cleaning software, so it's important to know how well a cleaning program performs the cleanup. Here you can test any cleaning software to see if it's really cleans any data stored in a Local Web Storage i.e a location on your computer where websites can store any kind of data e.g Cookies, Flash LSO etc.


We have tried to make this test simple and easy to understand as possible. However, before you take the test there are a few points that you should know:

• Almost all cleaning programs cannot delete browsing data while your browser is running!

• If you have installed Click&Clean and want to test another program, make sure you have deselected the " Delete private data when Chrome closes" checkbox.

Test Your Cleaning Program
