To keep your hardwood floors looking their best, it's a good idea to establish a care routine. Sweep your floors regularly, how often depends on how much foot traffic the room receives. You can also use a dry mop on your floors. Consult your manufacturer's recommendation before using any cleaning solutions on your hardwood. It is also a good idea to place doormats at the entryways in your home and remove your shoes when you're inside to reduce the amount of dirt on your floors.
No matter how careful you are, sometimes spills still happen. When you spill a solid, simply sweep it up. When you spill a liquid, use a clean cloth to blot up the spill. You can use a damp cloth to remove any residue from the area. Take care not to let water sit on your hardwood. Consult your manufacturer's recommendations before using any cleaning solutions.
If you see a spill persist and begin to stain, you should address it immediately. Consult your manufacturer's recommendation for products that are safe to use to lift the stain. Be sure to test a small area before proceeding.
