For this side of the home, the visible staining needed more than a quick spray. We used a controlled soft-wash process, checked the surface between applications, and protected the landscaping throughout the job.

Treatment used

An approximately 2% sodium hypochlorite soft-wash mix, applied two to three times where the organic growth required it. Sodium hypochlorite is the active cleaning ingredient professionals use to treat algae, mildew, and other organic buildup instead of relying on damaging high pressure.

Equipment used

A dedicated bleach-compatible soft-wash pump and application system designed to deliver the cleaning solution at low pressure, followed by a thorough fresh-water rinse.

Job process

1. 1Inspected the siding, staining, access, and nearby landscaping before treatment.
2. 2Pre-wet the shrubs and surrounding vegetation with fresh water for protection.
3. 3Applied the approximately 2% soft-wash mix at low pressure and allowed a controlled dwell period.
4. 4Checked the remaining growth and repeated the application two to three times where this side needed additional treatment.
5. 5Thoroughly rinsed the siding from top to bottom with fresh water.
6. 6Finished by rinsing the shrubs and surrounding areas again.

This describes this specific completed job—not a universal chemical recipe. Mix strength, dwell time, application count, equipment settings, and plant-protection steps are selected by I-Wash for each surface and condition. Professional handling and appropriate protective equipment are required.
