I just learned a new trick that I wished I'd had when all the drywall dust was flying.
Did you know if you place "Press N Seal" cling wrap to your keyboard, everything-including the mouse-trackpad still works?
But, no spills. No spaghetti sauces. No flour sifting through the keyboard at the same time!
I was just making bagels and afraid of having the flour go right through my macbook.
No worries anymore!
