Sodium Hypochlorite vs. Bleach: Understanding the Differences

Sodium Hypochlorite (NaOCl): This is the pure chemical compound, a powerful oxidizing agent. It's a clear, yellowish-green liquid with a strong chlorine odor. Key uses include disinfecting (killing bacteria, viruses, fungi), bleaching (removing stains), and water treatment.    

Bleach: In household terms, "bleach" typically refers to a diluted solution of sodium hypochlorite in water. It may contain other additives. The primary difference between bleach and pure sodium hypochlorite is concentration.    

For heavy-duty external cleaning, professionals often use higher concentrations of sodium hypochlorite, sometimes called "industrial-strength bleach." This tackles tough mold, algae, and stains on surfaces like concrete and siding. 

Household bleach, with its lower concentration, is suitable for lighter cleaning tasks. 

• Killing mold and mildew    

• Removing algae    

• Disinfecting surfaces    

• Whitening surfaces 

• Pressure washing large areas 

• Cleaning heavily soiled surfaces 

Sodium Hypochlorite:  

• Breaks down organic matter (mold, mildew, stains). 

• Can bleach or fade colored materials. 

• May corrode some metals.    

• Effectively cleans concrete and masonry, but excessive use can weaken them.    

• Is highly damaging to plant life. 

• Bleach (Chlorine Bleach):  

• Discolors materials by breaking down pigments.    

• Degrades organic materials (fabrics, wood). 

• Corrodes metals.    

• Can damage plastics, rubber, and painted surfaces.    

• Is highly damaging to plant life. 

• Can create toxic gasses when mixed with other chemicals.    

• Concentration: Higher concentrations are more potent and potentially damaging.

• Contact Time: Longer contact increases the effect. 

• Material Compatibility: Test on an inconspicuous area first. 

• Safety: Both are corrosive; use protective gear and ensure proper ventilation. 

• Environmental Impact: Both can negatively impact the environment. Dilute properly and limit run off. 

• Soft Washing: Its strength allows for effective cleaning of delicate surfaces without damaging high-pressure. 

• Pressure Washing: It ensures thorough eradication of organic growth, preventing rapid regrowth.
