Do PC Cleaners actually work?

There are many PC cleaners out there today, but most of them are not worth your time. In fact, some of them can actually do more harm than good. Many PC cleaners are designed to make you think that your computer is dirty and in need of a cleaning. They will often show you a list of "junk files" that they claim are slowing down your computer. However, in reality, these files are often harmless and can even be helpful. Some PC cleaners even go so far as to delete important system files. This can cause serious problems with your computer and even make it unusable.

However, a well-built cleaner that can safely clean substantial amounts of files can do wonders for your system. Having fewer temporary and junk files comes with many benefits, such as reduced tracking and privacy-exposing files, additional free disk space, a lower amount of files to load, less CPU usage, and faster hard drives. All of these would mean that your computer would have to work less and have a cooler CPU and system (less heat generated means a better life for your PC and components).

We kept all of that in mind when developing our PC Cleaner. We made sure that it is not only effective, but also completely safe. We ran several lab experiments with various other PC Cleaners, and we made sure ours came out at the top every test. This can be confirmed in our reviews section and across the media (just Google us). Our PC Cleaner is also completely free and comes with System Utilities, a trusted product designed to significantly speed up, clean, maintain, secure, and increase the battery life of your PC.

"PC Cleaner is unusual in that it actually freed up more space than CCleaner on our test system. And that's before we ran its Deep Cleaner"
