Oak Tree Tannin Stain Removal: Why Pressure Washing Alone Doesn’t Work

If you live in Florida and have oak trees around your home, you’ve probably noticed brown, tea-colored stains on your concrete driveway, sidewalks, or patio—especially after acorns and leaves fall.


These stains aren’t dirt or algae. They’re called tannin stains, and pressure washing alone will not remove them.


At Sunshine AquaWash, we frequently remove oak tree tannin stains from concrete driveways and walkways throughout Bradenton, Palmetto, Parrish, and surrounding communities.



What Are Oak Tree Tannin Stains?



Tannins are natural organic compounds found in oak leaves, acorns, and bark. When moisture hits these materials, tannins leach out and soak into porous surfaces like concrete.


Over time, this causes:


  • Brown or dark orange blotches

  • Stains that look “set in”

  • Discoloration that keeps coming back



Because tannins penetrate the concrete, standard pressure washing cannot break them down.



Why Pressure Washing Alone Won’t Remove Tannin Stains


Pressure washing is excellent for removing:


  • Dirt

  • Algae

  • Mildew

  • Surface grime


But tannin stains are a chemical stain, not surface buildup.


❌ More pressure won’t help

❌ Aggressive pressure can damage concrete

❌ The stains will still remain after washing


This is why many homeowners are frustrated after cleaning their driveway and seeing brown stains still there.

Not all stains can be removed with pressure washing alone. This video shows how we professionally remove oak tree tannin stains from concrete driveways in the Bradenton area.

We use a specialized stain removal process designed specifically for tannins:

This process safely dissolves tannins and restores the natural color of your concrete.



Real Results from Local Driveway Cleanings



We recently removed heavy oak tree tannin staining from a concrete driveway in Bradenton, where acorns had left deep brown discoloration across the surface.


The results were dramatic — stains that pressure washing couldn’t touch were completely broken down and removed.

Where Tannin Stains Commonly Appear


We most often see oak tannin stains on:


  • Concrete driveways

  • Sidewalks and walkways

  • Entryways

  • Patios

  • Pool decks

  • Street curbing under oak trees


If your property has mature oak trees, tannin stains are almost unavoidable without proper treatment.
