Keep out the rain

Remove residue with no-wax wood floor cleaner

Wipe up spills and dirt immediately; then use the cleaner to remove the residue. Dirt can damage the finish or get ground in. Liquids can damage the finish or stain the floor. It’s important to clean spills on wood floor quickly, but make sure you’re not over-cleaning these other areas of your house.
Know the rules about using waxes and restorers

It not only makes the floor far too slippery, it also interferes with subsequent finishes. If the finish is polyurethane, use a polish made for polyurethane. If it’s another type of surface finish, get a general-purpose floor restorer; test the restorer on an inconspicuous area to make sure it won’t peel off.
