How Bleach Breaks Down in Sunlight
Sodium hypochlorite, the active ingredient in bleach, is a powerful cleaner we use in our pressure washing process. But what happens after we’re done? Here’s the science:
Photodegradation Process
When exposed to sunlight, UV rays break down sodium hypochlorite (NaOCl) into sodium chloride (NaCl, table salt) and oxygen gas (O₂). This reaction is rapid in direct sunlight, often reducing bleach’s potency within hours. The chemical equation is:
2NaOCl → 2NaCl + O₂
Why It Matters
This natural breakdown means any bleach residue left behind after cleaning quickly becomes harmless salt and oxygen, minimizing environmental impact. Unlike persistent chemicals, it doesn’t linger in soil or water, aligning with our eco-friendly mission.
Factors at Play
- UV Intensity: Direct sunlight speeds up the process more than shade or cloudy days.
- Concentration: Our 12% sodium hypochlorite solutions degrade faster in sunlight than diluted mixes, ensuring quick cleanup.
- Heat: Sunlight’s warmth accelerates decomposition, making summer cleanups even greener.
Practical Takeaway
By leveraging bleach’s sunlight sensitivity, we ensure powerful cleaning that fades naturally, leaving your property spotless and the environment safe. Learn more about our methods on our Services page!
