If your deck is looking a little worn, dull or is getting slippery, it might be time for a stain – but be sure to clean it first. A stain won’t work on a dirty deck.
Deck stain is designed to soak into wood.
But if the wood is covered in algae, mildew, pollen, and leaf stains then the stain will bond to the grime layer instead.
We often see decks that were stained less than a year ago already coming apart because the surface was never prepped.
What cleaning does for your deck
We use a cleaning solution made for wood decks that breaks this stuff down into the grain, not just on the surface. Then we wash at the right pressure to clean the wood without tearing it up.
Using too much pressure on would can create splinters which would make staining even harder. It’s important that the deck is cleaned professionally so there’s no damage done.
After cleaning, some decks benefit from a brightener to restore the wood’s natural tone and balance the pH. This opens up the grain so stain can really penetrate.
We clean composite decks the same way!
After the deck is clean
Once it’s clean, it needs to dry completely for at least 48 hours of dry weather before any stain goes on. Staining damp wood traps moisture and shortens the life of the finish.
After it’s dry, you might not even want stain. A lot of people see their deck after a good cleaning and realize the wood looks great on its own. A clear sealer can protect it without changing the look.
If staining is the right call, it’ll actually work now. It’ll soak in, bond properly, and hold up the way it’s supposed to.
Our sister company Davis Painting handles deck staining in the same area — so if you need both cleaning and staining, we can make that happen pretty easily.
If you’re planning to stain this year
Get the deck cleaned first. It’s not optional if you want the stain to last.

How to Clean a Deck Before Staining
Preparation that lets stain penetrate evenly and bond to the wood rather than sitting on debris.
-
Clear the deck completely
Remove furniture, planters, and rugs, then sweep out the gaps between boards where leaves and grit collect. Anything left behind leaves an outline in the finished stain.
-
Apply a deck cleaner
Use a cleaner suited to your wood type and let it dwell for the time the label specifies. The solution does the work of lifting mildew and greyed fibers, not the pressure.
-
Rinse at low pressure
Use a wide tip held well back from the surface and keep the wand moving along the grain. Too much force raises the grain and leaves a fuzzy finish.
-
Sand any raised grain
Once dry, check for rough patches and sand them smooth. Skipping this step leaves a texture that absorbs stain unevenly and shows every mark.
-
Let the wood dry fully
Allow around forty eight hours of dry weather, longer for shaded decks. Staining over damp wood traps moisture and causes the finish to peel early.
Frequently Asked Questions
Why does a deck need cleaning before staining?
Stain has to penetrate the wood to bond. Dirt, mildew, pollen, and old degraded finish sit between the stain and the wood, so applying over them leads to blotchy color and early peeling.
How long should a deck dry before staining?
Around forty eight hours of dry weather is a common guideline, though damp conditions and shaded decks need longer. A moisture meter gives a more reliable answer than a visual check.
Can a deck be pressure washed safely?
Yes, at low pressure with a wide tip held well back from the boards. Too much force raises the grain and leaves a fuzzy surface that then needs sanding before any stain goes on.
