You should actually dilute it to about 70% with distilled water. It helps penetrate cell membranes and destroy them. You'd be surprised how much fungus and other nasty stuff appears over and inside old tech. I deal with camera lenses myself.

But yeah just buy the 99% stuff and some distilled water and do it yourself. You can wash down with distilled water too so having a few litres lying around is quite handy.
