Default Re: Cleaning PCB track side?

I can verify the need for caution when using a fibreglass pencil, I had a nasty experience with one over the weekend!
I was trying to remove some corrosion from a battery terminal, and suddenly remembered the "pencil". I was sat on the floor in the lounge, holding the offending component in one hand and cleaning it with the pencil. It worked a treat, and after a few minutes the contact was as good as new.As I stood up I noticed that my trousers were covered in a fine dust, and without thinking, I attempted to brush it off with my hand, it felt like I had grabbed a cactus plant!
I spent the next couple of hours with a torch, tweezers, and magnifying glass, extracting the splinters from my hand, to make matters worse I had to throw away a good pair of trousers, as I didn't fancy putting them in the wash.
Next time I need to use it, it will be outdoors and I'll be wearing gloves and safety glasses, I really wouldn't want a piece in my eye's, still lesson learned.
