What You'll Need: Castile Soap + Microfiber Mop
How Often You Should Clean It: Weekly
Sweep or vacuum, then mop. Since wood can warp if exposed to too much water, Hammersley mixes 1 teaspoon of castile soap into a 24-ounce spray bottle of hot water, then adds 10 drops of lemon or rosemary essential oil. She lightly spritzes the floor and wipes it with a microfiber mop. Her favorite non-DIY cleanser is Method Almond Squirt + Mop wood floor cleaner ($5, target.com).
Mop with warm water and an all-purpose cleaner. Avoid acidic ingredients like ammonia, which can discolor grout. Rinse; repeat with plain warm water.
Start in a corner and back your way out of the room, using arcing, overlapping mop strokes.
Here's how to keep those wood floors like new.
