Professional Soft Washing in Maryland
The safe, chemical-based cleaning method that outperforms pressure washing for delicate surfaces.
About This Service
Soft washing is the professional standard for cleaning surfaces that cannot tolerate high-pressure water — roofs, painted siding, stucco, EIFS, wood, and older masonry. Instead of relying on water pressure to blast away contamination, soft washing uses targeted, biodegradable cleaning solutions applied at low pressure to kill and dissolve mold, algae, bacteria, and organic staining at the molecular level.
OneNation Pressure Washing's soft wash system delivers results that last significantly longer than traditional pressure washing — typically 4 to 6 times longer — because it eliminates the biological growth causing stains rather than simply washing the surface appearance. The result is a cleaner property that stays cleaner longer, without any risk of surface damage from high-pressure water.
What’s Included
- ✓Safe on Delicate SurfacesRoofs, painted wood, EIFS, stucco, and older masonry can all be damaged by high-pressure washing. Soft washing cleans these surfaces without any risk of damage.
- ✓Kills Biological Growth at the RootCleaning solutions eliminate algae, mold, mildew, and bacteria — not just visually remove them. This means results last 4–6x longer than pressure washing.
- ✓Biodegradable SolutionsOur soft wash chemistry is biodegradable and breaks down safely after application. We pre-wet and protect your landscaping before every job.
- ✓Roof Warranty CompliantSoft washing follows ARMA guidelines and is the only cleaning method recommended by asphalt shingle manufacturers. High-pressure washing voids most roof warranties.
Our Process
Surface Assessment
We identify all surfaces to be cleaned, assess contamination type and level, and determine appropriate solution strength and dwell time.
Landscape Protection
All surrounding vegetation, planters, and landscaping are pre-wetted and protected before any cleaning solution is applied.
Solution Application
Biodegradable soft wash solution is applied at low pressure to all target surfaces, ensuring complete coverage and appropriate dwell time for maximum biological kill.
Low-Pressure Rinse
A gentle low-pressure rinse removes the cleaning solution and dead biological material. Results are often immediate and dramatic.
Plant & Landscape Safe
We pre-wet and protect every plant, shrub, and lawn bordering the work area before we start, and use biodegradable cleaning solutions that rinse clean. If anything in your landscaping is damaged by our work, we make it right at no cost to you.
Our Guarantee
If you’re not satisfied with the soft washing we did, we come back within 7 days and re-clean the area at no charge — no argument, no fine print.
Frequently Asked Questions
Pressure washing uses high-pressure water (1,500–4,000+ PSI) to blast away surface contamination. Soft washing uses very low pressure (under 500 PSI) combined with cleaning solutions to kill and dissolve organic growth. Soft washing is safer for delicate surfaces and produces longer-lasting results.
