About Cleaning Technique

Dayton Commercial Softwashing  Services


Your building's exterior is the first thing clients, customers, and tenants see. Dirt, algae, mold staining, and grime don't just look unprofessional — they signal neglect. Cleantec Softwash provides professional commercial exterior cleaning across Dayton and the surrounding Miami Valley, helping businesses, property managers, and facility directors maintain clean, well-presented properties year-round.


We use soft washing and pressure washing techniques matched to each surface type, so your building gets a deep, lasting clean without the risk of damage. No shortcuts. No subcontractors. Just experienced technicians, professional-grade equipment, and results you can see from the street.


Professional Commercial Building Washing for Businesses


Since 2012, Cleantec Softwash has been trusted by commercial property owners and managers throughout the Dayton metro for exterior cleaning that actually holds up. We work on everything from small retail storefronts to multi-unit office parks, industrial facilities, and managed HOA communities — adapting our methods to the specific needs of each property.


Every commercial job starts with a thorough site assessment. We identify surface types, contamination levels, drainage considerations, and any areas needing special care before a drop of water hits your building. That preparation is what separates a clean that lasts 12–18 months from one that fades in a season.


We are fully licensed and insured, and we carry general liability coverage for all commercial work. Certificates of insurance are available on request for property managers, facility directors, and commercial landlords.

Commercial Exterior Cleaning Services We Offer Near Dayton

We offer a full range of exterior cleaning services for commercial properties across Dayton, OH. Whether you need a one-time deep clean or a recurring maintenance program, we'll build a scope of work that fits your property and your schedule.


Commercial Soft Washing

Soft washing is our go-to method for most commercial building exteriors. Using low-pressure water combined with professionally formulated cleaning solutions, we remove algae, mold, mildew, lichen, and biological staining from siding, stucco, EIFS, painted masonry, and wood surfaces — without the high-pressure force that can damage finishes, force water behind cladding, or void roofing warranties.

The cleaning solutions we use target the root of biological contamination at the cellular level, which means results last significantly longer than a standard pressure rinse. Most treated surfaces stay clean for 12–24 months before needing retreatment.


   Safe for painted siding, vinyl, wood, stucco, and EIFS

   Removes algae, mold, mildew, lichen, and organic staining

   Results last 1–2 years in typical Dayton conditions

   No risk of surface damage, streaking, or water intrusion


Commercial Pressure Washing

For hard, high-density surfaces that can handle — and benefit from — higher water pressure, we use commercial-grade pressure washing equipment to blast away grease, oil, tire marks, chewing gum, and heavy buildup. This is the right tool for surfaces where soft washing alone won't cut through years of contamination.


   Concrete sidewalks, entry plazas, and common areas

   Loading docks and service entrances

   Parking garages and covered decks

   Dumpster pads and grease trap areas

   Retaining walls and decorative masonry


Building & Façade Washing

Your building's façade is your brand's physical face. We clean all common commercial cladding materials — brick, block, natural stone, metal panel, EIFS, and composite systems — using the method best matched to each substrate. Brick and mortar in particular require careful pressure management to avoid joint erosion; we adjust accordingly on every job.


For multi-story buildings, we have the equipment and training to work safely at height. We don't just do the easy ground-floor band — we clean the whole envelope, because a half-washed building looks worse than one that hasn't been touched.


Roof Cleaning for Commercial Properties

Black streaking on commercial roofs — that familiar dark discoloration creeping down from the ridge — isn't dirt. It's Gloeocapsa magma, a bacteria that feeds on the limestone filler in asphalt shingles and causes premature degradation. Left untreated, it shortens roof life, increases heat absorption, and raises energy costs.


Cleantec removes it using a soft wash approach endorsed by roofing manufacturers — no high-pressure tools that can dislodge granules or void warranties. We treat the source, not just the surface, so the staining stays gone.

   Safe for asphalt shingle, TPO, modified bitumen, and metal roofing

   Removes algae, lichen, moss, and organic buildup

   Manufacturer-approved low-pressure method

   Recommended by most commercial roofing warranty programs


Parking Lot & Concrete Cleaning

Parking lots and concrete surfaces take a beating — vehicle fluids, tire marks, food and beverage spills, general foot traffic grime, and seasonal road salt and debris all accumulate fast. A clean parking lot and entrance walkway signal a well-managed property. A grimy one tells customers something different before they ever walk through the door.


We offer hot or cold water pressure washing for concrete surfaces, depending on the contamination type, along with pre-treatment for oil and grease. For larger lots and shopping centers, we can schedule work during off-hours to avoid disrupting business operations.

Some of the most common issues we see on Dayton Buildings include:


  • Black Streaks on Roofs
    These streaks are caused by algae (Gloeocapsa Magma), which thrives in Ohio’s humid climate and can shorten the lifespan of your roof if not treated.
  • Green Algae on Vinyl Siding
    Shaded areas and moisture retention create ideal conditions for algae, leading to green film and discoloration that spreads quickly over time.
  • Mold and Mildew Growth
    Warm summers and wooded areas around Dayton contribute to mold and mildew buildup on siding, gutters, trim, and other exterior surfaces.
  • Dirt and Grime from High-Traffic Areas
    Buildings positioned near major Dayton roadways like I-75, I-70, and Route 35 often collect extra soot, dust, and pollutants throughout the year.
  • Rust Stains from Metal Fixtures and Hard Water
    Mineral-rich water and metal runoff can cause rust streaks on siding, concrete, parking areas, and walkways.
  • Organic Debris on Roofs and Gutters
    Leaves, twigs, and moisture accumulation create discoloration and potential deterioration when not properly maintained.


These issues not only impact curb appeal but can also lead to long-term exterior damage if ignored. Routine softwashing is one of the most effective ways to protect your building and maintain a clean, healthy exterior.
