Dust-off works well. However, due to the bitterant, it leaves a foul odor in the air when dispensed for too long. The can design needs work, if the sprayer comes off it is difficult to realign, making dispensing VERY difficult. Dust-Off DPSXL6 XL Compressed Gas Duster
It was buy a two-pack for $15, or a six-pack for $22. I went with the six-pack, tho i figure each can will last me half a year at least...
I use these to dust out my PC, and it works great. No complaints. - Compressed Air'
