What Aquapro Softwash Does and How It Differs From Pressure Washing

Aquapro Softwash uses low-pressure water and cleaning solutions instead of high-pressure jets

Aquapro Softwash is a cleaning method that sprays water mixed with biodegradable cleaning agents at low pressure—typically under 500 PSI—rather than the 3,000+ PSI that standard pressure washers deliver. The cleaning solution does most of the work, breaking down dirt, algae, mold, and mildew on surfaces. The low pressure means the water stream won't damage delicate materials like roof shingles, siding, wood decks, or painted surfaces that high-pressure equipment can gouge or strip.

The method got its name from Aquapro, a company that developed and marketed the softwash approach, though the technique is now used by many cleaning contractors across South Carolina and beyond. You'll see it advertised for roof cleaning, house washing, fence cleaning, and deck maintenance—jobs where pressure washing risks costly damage.

Key Takeaways

• Softwash uses low pressure (under 500 PSI) combined with cleaning solutions, while pressure washing relies on high-pressure jets alone.
• Softwash is safer for delicate surfaces like asphalt shingles, wood, vinyl siding, and painted finishes that pressure washing can damage.
• The cleaning solution kills algae and mold at the root, so results last longer than pressure-washed surfaces that get dirty again quickly.
• Softwash typically costs more per job than pressure washing because the process is slower and uses specialized equipment and solutions.

When softwash works better than pressure washing

Pressure washing is fast and powerful for concrete, driveways, and hard surfaces that can withstand the force. But on a roof, softwash is the safer choice. Asphalt shingles can be torn or stripped by high-pressure water, and the damage may not show until the next heavy rain. Softwash cleans the shingles without that risk, killing the algae and moss that cause dark streaks and deterioration.

Wood decks, fences, and siding also benefit from softwash. Pressure washing can splinter wood, open grain, and force water into seams where it causes rot. Vinyl siding can be cracked or pushed inward by high pressure. Softwash cleans these surfaces gently while the solution kills the organisms causing discoloration and decay.

Painted surfaces—exterior house paint, trim, garage doors—are vulnerable to pressure washing, which can peel or chip paint. Softwash removes dirt and mold without damaging the finish. Stained wood and composite materials also hold up better to low-pressure cleaning.

How the cleaning solution makes the difference

The solution used in softwash is the active ingredient. It typically contains surfactants (soap-like compounds that break down oils and dirt), biocides that kill algae and mold spores, and sometimes enzymes that break down organic matter. The solution is sprayed onto the surface and left to work for a period of time—sometimes minutes, sometimes hours—before a low-pressure rinse removes the loosened debris and dead organisms.

Because the solution kills mold and algae at the root rather than just blasting them away, the results last longer. A pressure-washed roof may look clean for a few months before algae returns. A softwashed roof stays cleaner for a year or more because the biocide in the solution has eliminated the spores. This longer-lasting effect is why many homeowners choose softwash despite the higher upfront cost.

Most softwash solutions are biodegradable and safe for landscaping, pets, and runoff into storm drains when used as directed. Always ask a contractor what solution they use and whether it's safe for your specific situation—especially if you have sensitive plants, a pond, or a septic system nearby.

Cost and time differences

Softwash jobs typically cost more than pressure washing the same surface. A pressure-washed driveway might run $200 to $400, while softwash for a roof or deck—which requires more solution, more time, and specialized equipment—often ranges from $300 to $1,000 or more depending on size and condition. The higher cost reflects the slower process, the cost of the cleaning solutions, and the expertise needed to apply them safely.

The job also takes longer. Pressure washing is quick—spray, rinse, done. Softwash requires application of the solution, a dwell time for it to work, and then a gentle rinse. A roof that takes two hours to pressure wash might take four to six hours to softwash. That time investment is part of why the price is higher, but it's also why the results are better and longer-lasting.

Finding softwash contractors in South Carolina

Many pressure washing companies in South Carolina now offer softwash as an option, especially those serving residential areas where roof and deck cleaning are common. Search for "softwash near me" or "roof cleaning" in your town to find contractors who advertise the method. Ask directly whether they use softwash or pressure washing, and what solution they use.

Check reviews and ask for references, particularly from jobs on roofs or wood surfaces. A contractor experienced in softwash will be able to explain why it's the right choice for your specific surface and what results you can expect. They should also discuss how long the results typically last and whether they offer any warranty or may provide on their work.

Softwash versus pressure washing: which to choose

Use pressure washing for concrete, asphalt, stone, and metal surfaces that are durable and won't be damaged by high pressure. It's faster, cheaper, and effective for heavy dirt and grime on hard surfaces.

Choose softwash for roofs, wood, vinyl siding, painted surfaces, and composite materials. It's gentler, kills organisms at the root so results last longer, and protects your investment in those surfaces. The higher cost and longer timeline are worth it to avoid damage and get longer-lasting cleanliness.

If you're unsure which method is right for your job, a reputable contractor can assess your surfaces and recommend the best approach. Many will offer both services and can tell you which one makes sense for each area of your property.

Frequently Asked Questions

Will softwash damage my roof shingles?

No. Softwash is specifically designed for roofs because the low pressure won't tear, strip, or lift shingles the way pressure washing can. The cleaning solution kills algae and moss, and the gentle rinse removes the dead material without harming the shingles themselves.

How long do softwash results last?

Results typically last one to three years, depending on your climate, shade, and how much moisture your surface gets. South Carolina's humidity and frequent rain mean algae can return faster than in drier regions, but softwashed surfaces still stay cleaner longer than pressure-washed ones because the biocide kills spores rather than just removing visible growth.

Is softwash solution safe for my plants and pets?

Most softwash solutions are biodegradable and pet-safe when used as directed, but it depends on the specific product. Ask your contractor what solution they use and whether you should water plants beforehand or keep pets away during application. Some contractors will take extra precautions around sensitive landscaping.

Can I softwash my driveway instead of pressure washing it?

You can, but it's usually unnecessary and more expensive. Driveways are concrete and can handle high pressure without damage. Pressure washing is faster and cheaper for driveways. Save softwash for surfaces that need gentler treatment, like roofs, decks, and siding.

Do I need to do anything to prepare for a softwash job?

Ask your contractor what preparation they recommend. For roof cleaning, you may need to move outdoor furniture or cover items that could get wet. For deck or siding work, move planters and secure loose items. Most contractors will give you specific instructions based on the job and the solution they're using.
