Why Does Concrete Stain in the First Place?

Concrete is porous and easily absorbs moisture, spills, and dirt. As a result, contaminants like oil, rust, grease, bird droppings, mold, and mildew penetrate deep below the surface rather than sitting on top. Dirt and foliage accumulate over seasons and stain the concrete gradually, while chemicals left on the slab react with it and cause discoloration. Consumer cleaners and rental equipment reach the surface but miss contamination sitting in the pores. Additionally, using the wrong cleaner on the wrong stain type can permanently damage the concrete.

Our Concrete Stain Removal Services

Different stains require different treatments.
Our crews assess each stained surface before selecting the cleaner and method,
protecting surrounding areas and using safety gear when working with harsh chemicals.

Oil and Grease Stain Removal

Oil stains come from equipment leaks, grills, and food grease soaking into the floor over time. Pressure washing alone simply moves oil around without pulling it out. We apply a commercial degreaser or oil-removing poultice, work it in with a brush, allow dwell time, and then power wash the surface clean. Deep stains get a trisodium phosphate solution in hot water first. Vinegar mixed with dish soap handles light, fresh oil marks.

Rust Stain Removal

Rust stains come from metal tools, furniture, and equipment left on concrete. A rust remover or mild acid-based cleaner designed for concrete dissolves the metal deposits without damaging the surrounding surface. Our cleaners foam as they react, confirming active removal from the pores. We test on a small area first — harsh acids on colored or stained concrete can alter the finish.

Organic Stain and Algae Removal

Mold, mildew, algae, bird droppings, leaves, and debris leave dark discoloration and etch into unsealed concrete quickly. Oxygen bleach or an outdoor concrete cleaner lifts organic staining when applied with a spray bottle, worked in with a brush, and thoroughly rinsed with a hose. Bird droppings clean up much like pet stains and need prompt attention.

Paint and Coating Removal

Paint spills require a paint stripper formulated specifically for masonry rather than a general-purpose product to soften the paint without attacking the concrete beneath it. Epoxy, wax, and similar coatings are matched to the appropriate solvent and dwell time.

Food and Household Stain Removal

Food grease, drink spills, and household messes absorb into unprotected concrete rapidly, and fresh stains lift far more easily than ones that have sat for months. We treat them with dish detergent, laundry detergent solutions, or commercial concrete cleaners depending on the stain, scrub the area with a brush, and rinse completely. Baking soda mixed with dish soap handles what remains.

Pressure Washing

A pressure washer removes surface grime, dirt, and algae across the entire area and handles many stain types once the right pre-treatment has done its work. We calibrate pressure to the surface condition — too much damages the concrete, too little leaves contamination behind.

Cleaning and Sealing

Stain removal prepares the surface for sealing. Once the concrete dries completely, we apply professional-grade sealant that locks contaminants out of the pores and prevents future stains from setting. A sealer also enhances the concrete's color and sheen. Reseal every 1 to 2 years depending on exposure and traffic.

Why Choose Teak & Deck Professionals?

Stains Pulled From the Pores

Consumer cleaners lack the concentration to reach contamination below the surface. Our degreasers, acid-based cleaners, and poultices are formulated to draw it out.

Right Cleaner, Right Stain Type

Using the wrong product causes permanent damage. We match treatment to stain, apply the correct dwell time, and power wash at the pressure the surface can take.

Sealed Against the Next One

Every stain removal finishes with sealant, so the clean surface stays clean and the next spill sits on top instead of soaking in.

The Concrete Stain Removal Process

STEP 01

Assessment and Quote

We identify the stain type, how long it has been there, and the surface condition, then confirm your price. A water test tells us whether existing sealant is present — beading means there's a sealer that affects how we treat the stain.

STEP 01

STEP 02

Preparation

We clear debris and dust from the entire area, protect surrounding plants and hardscape, and mask anything that shouldn't be touched. Careful preparation is what keeps a cleaning job from becoming a repair job.

STEP 02

STEP 03

Targeted Treatment

We apply the matched cleaner—whether it's a degreaser, acid-based rust remover, oxygen bleach, or masonry stripper—work it in with a brush, and allow full dwell time. We test in an inconspicuous spot first on colored or stained concrete.

STEP 03

STEP 04

Pressure Washing and Rinse

We power wash at the pressure the surface condition calls for, then rinse thoroughly with clean water until no cleaner or residue remains anywhere on the slab.

STEP 04

STEP 05

Drying, Sealing, and Walkthrough

The concrete dries completely before sealer goes on. We apply a coat of professional-grade sealant, then walk the finished surface with you and cover ongoing maintenance.

Get Rid of That Stain Before It Sets Permanently

Fresh stains lift easily. The same stain six months later has worked deep into the pores, and some — bird droppings
on unsealed concrete especially — etch the surface permanently. Request a quote, and we will match the right treatment to your surface and stain type.
