Reverse-osmosis and deionised (RO/DI) water is the backbone of how we clean. Here's how it compares in plain language.
| Topic | RO/DI purified water | Harsh chemicals | Untreated tap water |
|---|---|---|---|
| Coated solar glass & warranties | Gentle agitation with water formulated to leave no mineral film — aligned with how manufacturers expect panels to be washed. | Risk of damaging anti-reflective coatings or conflicting with manufacturer care guidance. | Dissolved minerals can dry as spots and build up over repeat visits. |
| Scratch risk | Soft brushes and controlled flow — no grit dragged across the glass. | Some products need aggressive scrubbing or tools that aren't panel-safe. | Particles in cloths or squeegees can still scratch if not managed carefully — we standardise kit and technique. |
| Streak-free windows | Deionised rinse dries clean — excellent for high glass and shopfronts. | Residue and fumes; often more rinsing and runoff to manage. | Hard water marks are common without filtration. |
| Water-wise mindset | We use what the job needs — pure water does more work per litre than flooding the roof with untreated water. | Chemical use adds disposal and environmental considerations. | Repeated heavy rinsing to fight spotting uses more volume overall. |
Our cleaning process
The same high standard on every job — from a single home to a multi-building estate.
We assess roof and glass access, weather, and your array before we start.
RO/DI water and soft brushes — no abrasives, no pressure washing on panels.
Thorough rinse and a careful pass so every panel and pane meets our standard.
Before/after photos where useful, then a clear wrap-up so you know the job is done.
