How to Clean Wood Stairs

How to Clean Wood Stairs. Cleaning your wooden stairs will prolong their life and maintain their beautiful appearance. Just follow these steps.


Thoroughly clean exterior wood stairs every 1-3 years. A sealant will help protect the stairs from the elements and sun exposure. If you do not know what type of finish is on your wood steps know that a surface finish is shiny and is sealed with polyurethane while a penetrating finish has a matte look and is sealed with an oil or wax finish. A frayed tipped broom will work best when sweeping. It will help pick up the smallest dirt particles. Sweeping, vacuuming or dusting the stairs daily will help prevent scratching the wood.


Never use ammonia on wood. Do not wax steps. Wax will make them slippery and dangerous.
