How to Clean a Wood Deck the Right Way

A winter of snow and ice can make your deck dirty, scratched, and worn down. Make your wood deck sparkle in time for spring. 

There are more than 40 million decks in the US that are more than 20 years old. If left uncared for, wood decks deteriorate over time. Don’t let your old deck wear down because it’s not looked after. 

If you want your deck to look great this summer, you need to know how to clean it the right way. Consistent and effective maintenance throughout the year is key.

With this guide, you’ll have all the information you need to know how to clean a wood deck.

Prep Your Deck

You’ve taken the first step and decided it’s time to clean your deck. It’s time to do a little prep work to make sure you get the most out of your cleaning efforts.

You need to get rid of any excess debris, such as paint chips, leaves, twigs, and so on. Don’t forget to get down between the deck boards. The gaps can get clogged with dog hair, for example. 

Take all the flowerpots, chairs, and any other items off your deck. Using a stiff-bristle brush or broom, give the deck a thorough sweeping.

Finally, wash down the deck with a hose. Use a strong flow, but not one that’s so strong it creates new debris on the deck or damages the wood.

How To Clean A Wood Deck

Choose a cloudy day for your cleaning. Too much sun will dry the cleaner too quickly. Rain will wash it away before you have a chance to clean it.

You can use any standard deck cleaner. Check the specific directions for the cleaner you choose. 

Use a stiff brush or a paint roller to apply the cleaner to the wood deck. After application, allow the cleaner to soak in for a while. Once you have covered the entire deck wash it off thoroughly.

A power washer is best for rinsing your deck. You can rent one from most hardware stores. Power washers aren’t that expensive so it might be best to buy one for longer-term use.


The last step in how to clean a wood deck is to seal it. This process is also the first step in long-term maintenance. 

Sealants come in a variety of finishes. Choose a clear one to preserve the natural wood finish or pick one that has a stain to add some color to the wood. 

You should reapply the sealant every couple of years. This ensures a well-preserved deck that will last longer. It also helps with future cleaning.

Cleaning your deck annually will keep it fresh and avoid mildew and rot damaging your wood deck.
