So to avoid glittery hands (the varnish runs due to the thickness I apply, two coats doesn't look as good as one coat simply loaded on) I filled my sink up with cold water and dipped my hands in for approximately a minute and a half. I believe the recommended time is between one and two minutes.
Overall this worked pretty well. I did however smudge a couple of bits when I was drying off my hands where the nail hadn't fully dried yet, so perhaps the full two minutes is required for complete effectiveness. I think next time I'll stick to my old technique: blowing on the nails every now and then and typing strangely if I have to.
