The Three Ingredients
Every soft washing job uses the same three-part system. No mystery additives, no shortcuts. Here's what each one is and why it's in the mix.
Sodium Hypochlorite (SH)
This is the active cleaning ingredient. It's the same compound as household bleach, but in a more concentrated form. Sodium hypochlorite kills algae, mold, mildew, and bacteria at the root — which is why soft washing results last significantly longer than a straight pressure wash. Pressure alone removes what's visible on the surface. SH eliminates the organism causing it, so regrowth is much slower.
The concentration varies by surface. Roofs typically get a stronger mix because they have heavier biological growth and the surface is more forgiving of a stronger solution. House washing uses a more diluted mix because painted siding, trim, and windows need gentler chemistry. Dilution is everything — getting it right is the skill, not just the application.
Surfactant
A surfactant — short for surface active agent — does several things at once. It helps the cleaning solution cling to vertical surfaces instead of running straight off before it can work. It breaks surface tension, allowing the SH to penetrate deeper into porous surfaces like stucco, concrete, and roof tile. And ours is scented, which means the job smells reasonably pleasant rather than like a swimming pool facility.
The surfactant we use is biodegradable. Once it's rinsed, it breaks down quickly and doesn't leave a residue.
Plant Neutralizer
This one is non-negotiable for us. Before we apply any cleaning solution near landscaping, we pre-wet all plants, grass, shrubs, and ground cover with a neutralizing solution. After the job is done, we rinse and neutralize again. Sodium hypochlorite can damage plant tissue if it lands on foliage undiluted or at full concentration — the neutralizer counteracts the SH and protects what's growing around your home.
Not every company does this step. We do it on every job. The landscaping goes in healthy, it stays that way.
Why Dilution Matters More Than People Think
The same chemical — sodium hypochlorite — is used at completely different concentrations depending on what surface we're cleaning. A roof soft wash uses a noticeably stronger mix than a house wash. A painted wood fence needs a gentler approach than concrete. Pool cage enclosures need care around the aluminum framing. Each surface has a right answer.
Too strong and you're risking the surface — etching paint, damaging sealants, or killing plants. Too weak and you're wasting time and product without getting the organic growth out at the root. There's no universal setting you just dial in. This is where experience matters: knowing the right mix for the surface in front of you is the actual job.
It's also worth noting that SH off-gasses quickly in Florida's heat. The concentration you apply is not what remains on the surface fifteen minutes later. This is why timing, dwell time, and immediate rinsing are all part of the process — not just steps to look thorough.
What About Pressure Washing?
For hard surfaces — concrete driveways, pool decks, pavers before sealing — the cleaning is primarily mechanical. The pressure and volume of water do the work. We still apply a pre-treatment detergent for stubborn organic growth like algae, mold, and oil staining, but the chemicals are milder because the pressure handles the heavy lifting.
For these surfaces, we use eco-friendly, plant-safe detergents only. No SH on a concrete driveway unless there's a specific reason for it. The goal is to match the right tool and chemical combination to the job — not to apply the strongest thing available and call it done.
Everything we use is biodegradable and properly diluted. We wouldn't spray anything on your property that we wouldn't spray on ours. The pre- and post-plant neutralization step is something not every company does — but it's just part of how we work. If you want to know the exact product we're planning to use on your specific job before we start, just ask. We'll tell you.
Is It Safe for Pets and Kids?
Once the solution has been thoroughly rinsed and the surface has dried — yes, completely safe. During application, we ask that pets stay inside and away from the work area. The cleaning solution is active and concentrated during application, and we don't want animals wandering through it.
By the time we've finished rinsing — which is always the last step — the chemicals are neutralized and diluted to safe levels. We'll let you know when it's safe to let the dog back out. That's a standard part of wrapping up every job.
Environmental Responsibility
All products we use are biodegradable. The rinse water that runs off your property is heavily diluted by the time it reaches ground level — the concentration of SH in the runoff is far below any meaningful threshold. We take care to direct runoff away from storm drains where the layout allows for it, and we use the minimum effective concentration needed for each surface. There's no benefit to using more chemical than necessary — it just costs more and creates unnecessary runoff.
If you have specific environmental concerns — a koi pond, a vegetable garden immediately adjacent to the wash area, a sensitive specimen plant — tell us before we start. We'll plan around it.
No mystery ingredients, no corners cut. If you ever want to know exactly what we're using on a specific job, call or text before we arrive. We'll walk you through it.
