The Pledge Multi-Surface Duster is different from other dusters out their because it comes with a small bottle of multi-surface spray in the handle of the duster. the most effective way to truly pick up the dust is to wet dust. Dry dusting often leaves some dust behind, but this traps in those extra dust particles leaving everything truly clean.
I really like the fact that they multi-surface spray is multi-surface. you can use it on a computer screen or on a table. The fact that you do not have to switch cleaners based on what you are cleaning cuts down on cleaning time.
My one complaint about this product is that it does not contain enough spray. I still had a clean duster, but no spray to finish up the job. I say if you are going to include spray you should include enough to get the job done!
