How conductive is cotton left on gpu

[spyguy]

I clean my gpu with cotton swabs, qtips to be exact and it works well but usually there will be a small hair size piece of cotton left snagged on one of the little silver pins on top of the gpu. I blow it off with compressed air but im a little ocd and its hard to get the thing completely spotless. So would a tiny hair size piece of cotton conduct electricity enough to cause a static discharge and fry the card? And also what type of brush should I get from the hardware store to prevent this type of problem in the future? And by that I mean what material should the bristles be?

It wont cause any harm.
I use personally brush for paintings ( the fine one) and acetone to clean gpu from dust, as part of old thermal paste, simple towel to wipe off and some more acetone.

And to add, i even spilled hot glue onto my R7 250 onto back with tranzistors and caps which is still working to its day

Is a polyester nylon brush safe to use? Will it short anything out?

No. Just dont press while brushing, let it slide across, Ive used on my both previous R7 250's and 1050ti without issue at all.
