We use a thin, microfiber cloth (which is included in the packing of our palette underneath the bubblewrap) and/or something called Take It For Granite which is a streak free granite cleaner that is environmentally friendly, cruelty free and best of all...doesn't streak. We then wipe the cleaner off in a "wax on, wax off" motion, with a microfiber cloth. We clean the inside - divider included, using a large powder brush to brush away any powder dust that's in the palette. For cream stains, we use a tiny bit of Take It For Granite and blot them away. Another cleaning solution that works well is Weinman granite & stone daily cleaner & polish.
