Hi everyone! I've had my MacBook Pro for a while now, and I was thinking of cleaning it, specially on the keyboard and vents and every little place that is impossible to clean with a cloth. So, I've come across air dusters, but I don't know if they might damage the computer. I'd also like to use this to clean my iPhone in a similar fashion. Is it okay to clean a computer like this, or is it better to use something like a toothbrush or a dedicated electronics brush?
