Hey guys, so today I decided to clean my PC after a couple months. Now, I use compressed air but after I was done...I noticed I still had a little later of dust still on it...is this normal or do you guys get everything off???

I cleaned the fans, filters (can't do my power brick as it's blocked off but I do have a filter below it).

Also just a quick question..I did take my PC outside to clean but I noticed a very tine bug went into my front panel case (used the spray on the inside), could this ah heck do damage?
