hi,
yes it can damage your new mobo !!!
use pure alcool to clean it, then dry it with soft paper.
Let it "sleep" for 2-3 hours, or use an aircompressor (those at gas station are also good).
Get an electronic spray cleaner and a teebrush, spray well and brush, and let it dry alone.
May be you can do it to your 1200 too !!
but orange juice is bad.... :roll:
