The Dust Remover by Clean Safe is a moisture free concentrated spray that blasts cold air to help you lift away small debris and dust from hard to reach places. I bought the Dust Remover so I could clean the many computer keyboards I had in my home and also clean the intake on those computers so it would stop overheating due to the dust. For a good price at Walmart, you get 20% more than the average brand by buying this particular brand. The can is very easy to set up and you are spraying in seconds. The spray comes with a very thin straw so the air is very concentrated. The can is very easy to spray and air comes out with strength. It did a good job in cleaning and blasting away dust in small cracks on my computer and my phone. The only downside to these types of cleaning products is that the can becomes extremely cold due to the pressure release and it may be too cold to hold on its own. Also, it is dangerous around some kids because it is known as a substance you can get high on. But for the uses it is intended for, the Dust Remover is a very effective and cost efficient solution for those hard to reach places where dust can be blasted away.
