Where can I buy circuit board cleaner?
i use engine antifreeze if i dont have any alcohol for cleaning my CPU/heatsinks. As for dust removers which is what i think you are looking for, walmart has them for 5$ or soemthing, Zellers for 9.99, radioshack for 7.99, The source 7.99, Microbytes 2.99, and just about every other major retailer or PC store. Including Best buy and staples but i didnt know their prices.
I'm Canadian, although newegg is now an option, its garbage compared to other options.
