Leaf Stains on Your Driveway or Patio: Why They Happen and What Removes Them
Those brown leaf prints are tannins, not dirt. Here's how to get them out and keep them out.

The short answer
Leaf stains are tannins, the same plant compounds that color tea. A wet leaf sitting on concrete for a few days leaches them into the surface. Fresh marks often lift with a sweep and a rinse. Set-in stains spread across a drive or patio come out evenly with a pressure wash and the right pre-treatment. Clear leaves off before they sit through a rain and most stains never form.
Rake the last of the maple leaves off the driveway and there it is: a brown silhouette of every leaf that sat there through the last rain. It's one of the most common calls we get in late fall around Dayton.
I'm Anthony. A Team Contracting is a family-owned crew out of Tipp City, and we pressure wash driveways, sidewalks and patios across the Miami Valley. Here's what those stains are and what actually gets them out.
What leaf stains actually are
Leaves contain tannins, the same natural compounds that color tea. When a wet leaf sits on concrete or pavers, the tannins leach out and soak into the pores of the surface. That's why the stain is shaped like the leaf, and why it shows up worst where leaves sat wet for days: under the maple, along the edge of the patio, in the low spot by the garage.
It isn't dirt and it isn't algae. That matters, because the fix is different.
Leaf stain, algae or rust? How to tell
| What you see | Likely cause | Where to read more |
|---|---|---|
| Brown or tan marks, leaf-shaped | Tannins from wet leaves | This guide |
| Green or black film, worst in shade | Algae and mildew | Green algae on a driveway |
| Orange streaks or spots | Rust from fertilizer, furniture or well water | Concrete cleaning |
Plenty of driveways have all three. We look at what's on the slab before we pick a pre-treatment, because rust needs a rust-specific treatment, not more pressure.
What you can do yourself
- Get leaves off fast. Most tannin staining needs a few damp days to set. Blowing the drive off after a windy day or before a rain prevents most of it.
- Rinse fresh marks. A new, light stain often fades with a sweep, a garden-hose rinse and a few sunny days.
- Use an oxygen-based cleaner on set-in spots. Tannins respond to oxygen-based (non-chlorine) cleaners with some dwell time. Follow the label and keep it off your plants.
- Skip the wand tip. A rented pressure washer with a narrow tip chases one stain at a time and leaves stripes and etched lines in the concrete. That damage is permanent.
When a pressure wash makes sense
If the stains are scattered across the whole driveway or patio, spot treating turns into a patchwork. That's when a professional wash pays off. Concrete gets pressure washed. We pre-treat, then run a rotating surface cleaner that holds the same distance across the whole slab, so the finish comes out even instead of striped. Then we detail the edges and rinse.
One honest note: tannins that have baked into old, porous concrete for several seasons may lighten a lot rather than vanish completely. We'll tell you that before we start, not after.
Price: these are the ranges on our pricing page. A 1–2 car driveway runs $150–$225, a 3-car or extended drive $225–$300, a patio up to 400 sq ft $125–$250, and a front walk $75–$150. Bundling the drive, walk and patio on one visit costs less than separate trips.
"So pleased with the work Anthony from A Team Contracting did on our driveway and sidewalks. The method he used pressure washing made all the difference. It looks brand new! Thank you so much! Tina J., Tipp City Ohio"

Timing it with Dayton leaf pickup
The City of Dayton's loose-leaf curbside collection runs from Oct. 19, 2026 through Jan. 4, 2027, with at least two passes per neighborhood. Leaves need to be at the curb by 8 a.m. Monday of your pickup week, and bagged leaves aren't collected.
That makes a simple plan: get the leaves off the concrete and to the curb, then wash once the trees over the drive are bare. Washing before the last drop means new leaves land on clean concrete and start the cycle again. If gutters are on your list too, the timing lines up with our guide on when to clean gutters in fall, and we can do both on one visit.
For property managers and HOAs
Leaf stains on shared sidewalks, entry walks and pool decks are the first thing residents and buyers notice. We can wash common flatwork across several buildings on one schedule. See our commercial pressure washing in Dayton page, or call to set up a walk-through.
Siding is a different job. If the walls are green too, that's a soft wash, not a pressure wash. See house washing in Dayton.
