Here in Myrtle Beach we get rainfall well over the national average, and this can take a serious toll on your hardwood floors. Ambient humidity, combined with water being tracked into the home on rainy days, can really put the hurt on your floors in many ways.
First, and most important, never allow water to sit on your floor for very long. It is of the utmost importance that any standing water be thoroughly dried as soon as possible. When mopping, try to use a damp, not wet, cloth or mop. Even better, use a micro fiber mop, like a Swiffer, to clean your hardwood. Be sure to dry the floor with a clean dry cloth as best as you can after mopping.
That's easy enough, but an even better way of taking care of the water problem is to prevent it in the first place. There are a few things you can do to stop water from ever having a chance to get on the floor.
Putting down mats in front of sinks and dishwashers, is a great way to minimize the effects of water damage to your kitchen floors. The same can be said for the floors of your bathroom in the event that they are hardwood.
Placing mats on the inside of any doors leading to the outdoors, is another great way to keep water from being tracked around the house. Beyond that you may want to institute a policy of disallowing shoes in the house altogether. Not only will this cut down on the amount of water being spread through the house, but it will also save your floors from the damage of dirt and sand that have a tendency to erode the finish of your floors.
With just these few tricks, you should be able to keep your floors looking brilliant for years, even decades to come.
