Commercial Soft Washing in South Florida
The safe, effective alternative to high-pressure washing for stucco, EIFS, painted facades, and architecturally sensitive surfaces.
Not every commercial surface can or should be cleaned with high-pressure water. Stucco, EIFS (Exterior Insulation and Finish Systems), painted concrete, fiber cement siding, and many historic building materials require a low-pressure, chemistry-driven cleaning approach to remove biological growth and soiling without cracking, pitting, or delaminating the surface. TitanFlow Exteriors' commercial soft washing service uses biodegradable surfactant blends applied at under 500 PSI to kill mold, algae, mildew, and lichen at the root — providing results that last far longer than high-pressure washing alone, without the surface damage risk.
Our Process
Soft washing is fundamentally different from pressure washing in its operating principle. Where pressure washing uses mechanical force (high PSI) to dislodge surface contamination, soft washing uses chemistry — specifically, surfactant and biocide solutions — to kill, loosen, and float contamination off the surface at pressures that are safe for delicate materials. Our commercial soft wash system applies a blended solution of sodium hypochlorite (at a commercial concentration appropriate for the surface and contamination type), a surfactant to increase surface contact time and penetration, and a neutralizer to protect surrounding vegetation and surfaces.
Solution is applied from the bottom of the surface upward to prevent streaking, allowed to dwell for 5–15 minutes depending on the contamination type and intensity, and then rinsed from top to bottom at low pressure (150–500 PSI). This dwell time is critical — it allows the biocide to penetrate the algae or mold colony and kill the organism rather than just washing away the surface layer. The result is a cleaner surface that stays clean significantly longer than pressure-washed surfaces where the root of the biological organism remains embedded in the substrate. For multi-story soft wash applications we use a proportional injector system that delivers solution through standard garden-hose-pressure supply lines, eliminating the need for aerial access in many cases.

Common Questions
What is the difference between soft washing and pressure washing?
Pressure washing uses high PSI water force (2,000–4,000 PSI) to mechanically remove surface contamination. Soft washing uses low pressure (under 500 PSI) combined with a biocide surfactant solution to chemically kill and remove biological growth. Soft washing is required for surfaces that would be damaged by high pressure and produces longer-lasting results by killing organisms at the root.
Is soft washing safe for all exterior surfaces?
Soft washing is the safest cleaning method for most coated, painted, or architecturally delicate surfaces. It is specifically recommended for stucco, EIFS, painted concrete, fiber cement siding, and historic masonry. For unpainted hard concrete, brick, and pavers, standard pressure washing is more appropriate and efficient.
How long do soft wash results last compared to pressure washing?
Soft washing typically provides 2–4 times longer results than pressure washing for biological growth because it kills the organism rather than just removing the surface layer. A pressure-washed stucco facade in South Florida may re-green within 6–12 months; a properly soft-washed facade may stay clean for 18–36 months depending on shade, humidity, and irrigation exposure.
Is the bleach in your soft wash solution harmful to landscaping?
When applied correctly, no. We pre-wet all surrounding vegetation before applying solution, use surfactant blends that help the solution cling to the target surface rather than running off into landscaping, and rinse all vegetation thoroughly after the wash. We also apply a neutralizer to offset pH impact on plants. We have cleaned thousands of South Florida properties without landscape damage.
Can soft washing remove mold from stucco without damaging it?
Yes — soft washing is the recommended method specifically because it removes mold safely from stucco. High-pressure washing can crack stucco, drive water behind the surface into the substrate, and introduce moisture that accelerates future mold growth. Soft washing kills the mold at the root without hydraulic force.
Do you soft wash EIFS (Dryvit) commercial facades?
Yes. EIFS is one of the primary applications for our commercial soft wash service. EIFS manufacturers explicitly warn against high-pressure washing, which can delaminate the finish coat and damage the insulation layer. We use EIFS-safe surfactant concentrations and verify solution strength before applying to any EIFS surface.
Can soft washing remove black streaks from painted buildings?
Yes. The black streaks common on South Florida buildings are caused by Gloeocapsa magma — a photosynthetic cyanobacterium — and respond directly to sodium hypochlorite biocide treatment. Soft washing eliminates these streaks and, by killing the organism, prevents rapid re-staining.
How often should a stucco commercial building be soft washed?
In South Florida's humid climate, annual soft washing is typical for stucco commercial buildings with normal sun exposure. Buildings with north-facing facades, under heavy shade, or exposed to irrigation overspray may need biannual treatment due to faster biological growth. We will recommend a frequency based on your building's specific exposure conditions.
Is soft washing available for historic buildings in South Florida?
Yes. We are experienced working with historic commercial properties where preservation requirements prohibit high-pressure cleaning. We can provide documentation of our method and solution concentrations for review by historic preservation consultants or boards if required by your project.
Do you offer a warranty on soft wash results?
We stand behind our work — if biological growth returns to a soft-washed surface within 90 days of service under normal conditions, we will return and retreat at no charge. Recurring maintenance contract clients benefit from this coverage on an ongoing basis.
