I would like to strait some things out that has been bothering me..
over time ive read more and more recent posts by ppl who mostly know bogus about repairing and the fact of using an old toothbrush to clean, this is quite dumb for a lot of reasons.. main reason meantioned here.
if you are planning to use a toothbrush to clean your console or whatever.. dont use an OLD USED one!!!! since most toothpastes has cemicals within them who are harmful to electronics witch in some cases cause more damage then fixing. and ALSO NEVER EVER IN HELL use water unless your cleaning something NONE electronical like plastic. even if you cant see it water soaks into viaholes and other gaps on pcb's and components and forms crystals witch in time causes inreversable damage !!! this is also why normal Alcohol aka moonshine shouldnt be used do only use Electronic-Alcohol (isopropanol) can be found at a local drugstore probably if asked for.
