How I fixed a situation with powder brush

So I bought a new sound card and to install it I had to move my graphics card from PCIe2 to PCIe3 slot (it was in PCI2 because it was better for ventilation that way) and when I installed into PCI3 my PC refused to recognize there's a card in the PC no matter what I did - changed bios settings, reinstalled bios. Everything was perfectly connected. I was about to downgrade my gpu bios when I came up with an idea: I took my sisters powder brush and cleaned the PCI3 slot a bit with it. I also took a screen cleaning tissue and cleaned the gpu's contacts a little. Voila. Works perfectly in PCI 3 now :D

People used to use pencil eraser to clean gpu contacts. Not sure about cleaning the slot itself.
