Some surfaces can't handle high pressure. We use biodegradable solutions and gentle water flow to kill mold, algae, and grime at the root — safely, effectively, and for longer-lasting results.
Quick answer: Soft washing is a low-pressure exterior cleaning method (under 500 PSI) that uses biodegradable cleaning solutions to safely remove mold, algae, mildew, and grime from delicate surfaces — roofs, siding, stucco, painted wood — without the risk of damage that comes with standard pressure washing.
The first time I explain soft washing to a homeowner, they usually ask: "So is it less effective?" Understandable question. The answer is actually the opposite.
Soft washing doesn't just rinse the surface. The cleaning solution penetrates into the mold and algae colonies and kills the spores at the root. Pressure washing alone blasts the visible growth away — but it leaves the root system behind. Six months later, you're looking at the same problem.
That's why soft wash results typically last 2–3 times longer than pressure washing on the same surface. You're not just cleaning — you're treating.
✅ Industry note: The Asphalt Roofing Manufacturers Association (ARMA) specifically recommends low-pressure soft washing as the only approved cleaning method for asphalt shingles. High-pressure washing strips granules, accelerates shingle aging, and voids most roofing warranties.
The process is straightforward, but the chemistry and technique matter. Here's what happens from start to finish when Mr-Suds soft washes your property.
We identify surface type, contamination level, and any areas needing extra care before applying anything.
We wet down surrounding landscaping and cover sensitive plants. Your garden is protected before we start.
Biodegradable cleaning agent is applied at low pressure. It begins breaking down mold and algae within minutes.
The solution sits and works into the organic growth. This is what kills spores at the root — not just the surface.
Low-pressure rinse removes the solution and loosened contaminants without stressing the surface material.
We inspect every surface with you before packing up. If something isn't right, we fix it on the spot.
This is genuinely one of the most important questions in exterior cleaning. Using the wrong method on the wrong surface causes real, expensive damage. Here's a clear breakdown:
| Factor | 🌿 Soft Washing | 💪 Pressure Washing |
|---|---|---|
| Water Pressure | Under 500 PSI | 1,500–4,000 PSI |
| Cleaning Mechanism | Chemical solution kills mold/algae at root | Physical water force blasts surface grime |
| Best Surfaces | Roofs, siding, stucco, wood, painted surfaces | Concrete, brick, stone, pavers, driveways |
| Results Duration | 1–3 years | 6–12 months |
| Safe for Asphalt Shingles | ✓ Yes — ARMA approved | ✗ No — voids warranty |
| Safe for Vinyl Siding | ✓ Yes | ⚠ Risk of cracking/forcing water behind |
| Kills Spores at Root | ✓ Yes | ✗ Surface only |
| Eco-Friendly | ✓ Biodegradable solutions | Depends on detergents used |
⚠️ Critical mistake homeowners make: Hiring a general pressure washing company and assuming they'll know which method to use. Many don't. High-pressure washing on a roof removes shingle granules — the protective layer that shields your home from UV and rain. Once those granules are gone, the shingle clock starts ticking fast. We always assess the surface first.
At Mr-Suds, we use both methods — the right one for each surface. Most full-home jobs use a combination: soft wash for siding and roof, higher pressure for the driveway and concrete. That's the professional approach.
We'll assess it for free. One call — we'll tell you exactly what your property needs and what it costs.
Soft washing is the right choice for any surface that can be damaged by high pressure. Here's what we treat regularly across Connecticut homes and businesses.
Removes black streaks (Gloeocapsa Magma algae), moss, and lichen. The only safe cleaning method for asphalt shingles per ARMA guidelines.
Kills algae and mildew without the risk of cracking panels or forcing water behind the siding — a real concern with high-pressure methods.
High pressure splits and splinters wood grain. Soft washing cleans safely, preserving the wood's structure and finish.
Stucco is porous and highly pressure-sensitive. Soft washing removes mold and discoloration without cracking or eroding the surface.
Removes organic staining and brightens gutter exteriors without bending or denting aluminum with excessive water force.
Eco-friendly, low-disruption cleaning for business exteriors. Safe for signage, cladding, and areas with pedestrian traffic nearby.
Commercial jobs need a different kind of coordination — scheduling around business hours, managing access, protecting signage and lighting. We've done it enough times to handle it efficiently without disrupting your operation.
Homeowners often ask why their siding or roof looks dirty again just months after a standard pressure wash. The reason is simple and frustrating: pressure alone doesn't kill algae. It displaces it.
Algae and mold attach to surfaces with root-like structures called rhizoids. A pressure washer blasts away the visible growth on top — but those rhizoids stay embedded in the surface material. Given warmth and moisture, they regrow fast. In Connecticut's humid summers, that can mean visible regrowth in as little as 4–6 months.
The biodegradable solution we use — a professionally formulated mix of sodium hypochlorite and surfactants — penetrates the surface and kills the algae colony at the cellular level. Roots included. The result stays cleaner for 1–3 years depending on sun exposure, tree coverage, and surface type.
This is why most professional exterior cleaning organizations recommend soft washing over pressure washing for organic stains on roofs and siding.
Connecticut has plenty of pressure washing companies. Far fewer actually specialize in soft washing — and even fewer do it correctly. Here's what sets us apart.
✅ From the field: One of the most common calls we get is from homeowners who tried DIY soft washing with store-bought bleach and ended up with streaks, dead plants, or surfaces that stayed dirty. The chemistry matters. Formulation, dwell time, and rinse technique all affect the outcome. It's worth doing it right the first time.
Honesty matters to us more than just getting the job. Here's what soft washing genuinely can and can't do:
If we see something that soft washing won't fully resolve, we'll tell you that during the estimate — before any work starts. Our goal is results you're satisfied with, not just a completed invoice.

Soft washing is a low-pressure cleaning method (under 500 PSI) that uses biodegradable cleaning solutions to safely remove mold, algae, mildew, and organic staining from delicate surfaces. Unlike pressure washing, it kills the contamination at the root rather than just rinsing the surface.
Yes — it's actually the only recommended method. The Asphalt Roofing Manufacturers Association (ARMA) specifically states that low-pressure soft washing is the correct approach for asphalt shingles. High-pressure washing strips granules, shortens roof lifespan, and often voids the manufacturer's warranty.
Typically 1–3 years, depending on your home's sun exposure, tree coverage, and moisture levels. Because soft washing kills spores at the root, regrowth is significantly slower than after pressure washing alone. Shaded, north-facing surfaces may need retreatment sooner than sun-exposed areas.
Yes. We use biodegradable, professionally formulated solutions that break down safely after application. Before starting, we wet down surrounding plants and protect sensitive landscaping. We rinse the area thoroughly after the treatment. Your garden and pets are safe.
For a standard Connecticut home, soft washing ranges from $200–$500 depending on size and how much surface area needs treatment. Roof-only soft washing typically runs $150–$350. We give you a free, written estimate after inspecting the property — no guesswork or surprise charges.
Pressure washing uses high water force (1,500–4,000 PSI) to physically blast surface grime. It works well for concrete and hardscape but can damage siding, roofs, and painted surfaces. Soft washing uses low pressure and lets the cleaning solution do the work — making it safer for delicate materials and longer-lasting in results. Learn more about our pressure washing service here.
Not necessarily. As long as we have access to the exterior and an outdoor water connection, we can complete the job without you present. We'll walk through the results with you before we leave — in person or via photos if you prefer.
Yes. We clean commercial properties across the Hartford area including storefronts, office building exteriors, and multi-unit residential buildings. Scheduling can be arranged around business hours. Contact us to discuss your project.
Once a year covers most Hartford-area homes. Homes with heavy shade, mature trees, or significant north-facing siding may benefit from treatment every 6–12 months. After your first professional soft wash, Roman will give you an honest recommendation based on what your specific property needs.
