Here's something most Toronto homeowners don't know: your storm drains flow directly to Lake Ontario with zero treatment. Every drop of chemical cleaner that washes off your windows during cleaning enters the lake untreated. Ammonia, surfactants, degreasers — all of it.
ClearCoat™ purified water eliminates this entirely. The only thing that touches your windows — and washes into your garden and storm drains — is pure H₂O. And counterintuitively, it cleans better than chemicals.
Chemical Cleaning vs Purified Water: The Comparison
| Factor | Chemical Cleaning | ClearCoat™ Purified Water |
|---|---|---|
| Chemicals used | Ammonia, surfactants, degreasers | None — pure H₂O only |
| Garden safety | ❌ Kills plants, changes soil pH | ✅ 100% safe (pH 7.0) |
| Pet safety | ❌ Toxic if ingested from puddles | ✅ Drinkable water |
| Child safety | ⚠️ Residue on windows, skin irritant | ✅ Zero residue |
| Lake Ontario impact | ❌ Storm drains → lake untreated | ✅ Pure water only |
| Residue on glass | Chemical film + mineral deposits | Zero — dries invisible |
| Clean longevity | 2-4 weeks before re-soiling | 6-12 weeks |
| Streak risk | High (residue dries visible) | Zero (nothing to dry) |
| Cost | $149-$349 | $149-$349 (same price) |
🌿 The Lake Ontario connection: Toronto's 5,700 km of storm drains flow directly to Lake Ontario — no water treatment plant in between. Unlike sanitary sewers (which go to treatment), storm drains are direct pipes to the lake. When a window cleaner uses ammonia on your 2nd-floor windows and it washes down into your garden, it enters the soil. When rain hits that soil, it carries those chemicals to the nearest storm drain. From there: straight to the lake. Every eco-friendly cleaning choice protects the lake your grandchildren will swim in.
Why Pure Water Cleans Better Than Chemicals
This surprises people: purified water is a more aggressive solvent than chemical-laden water. Here's the science:
- Pure water is "hungry" — with 0 dissolved solids, every water molecule is actively seeking to dissolve and absorb contaminants. It's thermodynamically unstable, which makes it an excellent cleaning agent.
- Chemical cleaners add residue — surfactants break surface tension (good) but deposit their own film on glass (bad). That film attracts new dirt faster than clean glass.
- Temperature + agitation — ClearCoat™ water is delivered at room temperature through brush heads that physically agitate dirt. The combination of pure water's dissolving power and mechanical action outperforms chemical surface-tension breaking.
- Zero-residue drying — when purified water evaporates, nothing remains. When chemical-laden water evaporates, its dissolved solids and surfactant residue stay on the glass.
The result: ClearCoat™ cleaned windows stay clean 2-3x longer than chemically cleaned windows because there's no residue film for new dirt to stick to.
Safe for Your Specific Garden
Toronto's garden-proud homeowners spend thousands on landscaping. Here's what common cleaning chemicals do to gardens:
| Chemical | Garden Impact | Soil Impact |
|---|---|---|
| Ammonia (Windex, etc.) | Burns leaves, kills beneficial insects | Nitrogen spike → algae in soil |
| Bleach (sodium hypochlorite) | Kills all vegetation on contact | Kills soil microorganisms for months |
| Surfactants (dish soap) | Coats leaves, blocks photosynthesis | Reduces water absorption |
| Acid cleaners (CLR, etc.) | Changes soil pH, burns roots | Can make soil toxic for years |
| ClearCoat™ purified water | ✅ Actually waters your plants | ✅ Rinses away salt deposits |
Rose gardeners, take note: Roses are particularly sensitive to pH changes and chemical residue. If your rose beds are below or near windows that get professionally cleaned, ask your cleaner what they're using. Ammonia runoff on roses causes leaf burn within 24-48 hours. ClearCoat™ runoff? It's better than your hose water — it doesn't have Toronto's 124 mg/L of dissolved minerals that cause hard water buildup on soil.
The Carbon Footprint Comparison
- Chemical cleaning: Manufacturing chemicals + plastic bottle packaging + chemical transport + disposal = significant carbon footprint per job
- ClearCoat™ system: One reusable filtration system processes tap water on-site. No chemical manufacturing, no plastic bottles, no chemical transport. The only input is municipal water and filter replacements (every 6-12 months)
- Water usage: ClearCoat™ water-fed poles use approximately 4-8 litres per window — less than a standard kitchen tap running for 2 minutes. A full house cleaning uses less water than one load of laundry
