To make your holiday decorating way more fun, it’s a great idea to dust before decorating.
It sounds like it will be a huge job, but since you’re moving everything around anyways, it will be super fast.
I usually take my big Christmas bucket, empty all of my decorations onto the kitchen counters, and then take down all of my regular decorations to be stored in the bucket, and dust the empty mantel, tables, curio cabinet, china cabinet and so on. I love Pledge for the wood and Windex Multi Surface for everything else.
Have fun decorating your space with a nice clean surface!
