I opened up my pc for the first time ever and realised there was SO MUCH DUST. It's all over the hard drive, fans are covered and theres a bit on my wireless and graphics card as well as my cd drvie. I have a can of compressed air, wet cleaning wipes, dry cleaning wipes and absorbing cleaning wipes. How do I use these to clean the insides of my computer? (These were all inside a "computer cleaning kit")
