Unlike high-pressure washing, soft washing uses low-pressure water and biodegradable cleaning solutions to remove grime, algae and organic growthsoftwashdoctors.com. The key is to clean effectively without risking damage to the panel or roof.
- Low Pressure: Soft washing avoids powerful jets. Pressure washers can crack the glass or dislodge panel seals. In fact, one cleaning service warns that pressure washers are “too violent” and can reduce panel lifesoftwashdoctors.com. Soft washing uses a simple spray and brush method to gently lift dirt.
- Eco-Friendly Cleansers: Technicians mix mild, biodegradable detergents that break down moss, pollen or guano. These solutions disinfect and clean without leaving harmful residues. Panels treated with a soft wash solution often stay cleaner longer.
- Mineral-Free Water: Many soft-washers use purified or deionized water, which leaves no mineral streaks. As Softwashing UK notes, plain tap water is “not up to the task” because minerals can deposit on panelssoftwashinguk.co.uk. Soft washing typically uses water fed through filters to ensure a spot-free rinse.
