Hi eR1c!
The only time I sand dirty electric metal contacts is when I am soldering. As you said, gold plating allows corrosion-free use for a long time. If anyone sands that plating off, you are now exposing metal to the environments which will corrode over time increasing resistance.
I've never had to sand my Deans connectors though.
