Bleach Dilution Calculator
Calculate bleach dilution ratios for cleaning and disinfection. Mix water and bleach safely for effective sanitization at recommended concentrations.
About This Calculator
The Bleach Dilution Calculator helps you determine the correct amounts of bleach and water to mix for effective disinfection and cleaning.
Using the standard dilution formula (C1 x V1 = C2 x V2), the calculator determines exactly how much bleach concentrate and water you need to achieve your target concentration and volume.
Features:
- Accurate calculations using verified formulas
- Two chart views for data visualization
- Detailed breakdown of bleach and water amounts
- Shareable calculation links
Frequently Asked Questions
What is the recommended bleach concentration for disinfection?
CDC recommends 0.1% sodium hypochlorite (1:50 dilution of 5% bleach) for general disinfection, and 0.5% (1:10 dilution) for blood spill cleanup. Always add bleach to water, not water to bleach, and never mix with ammonia.
How do I calculate bleach dilution?
Use the formula: C1 x V1 = C2 x V2, where C1 is the initial bleach concentration, V1 is the volume of bleach needed, C2 is the target concentration, and V2 is the final volume. Our calculator handles this automatically.
Is this calculator free to use?
Yes, it is completely free with no registration required. Use it unlimited times.
Can I share my calculation results?
Yes, your inputs are saved in the URL automatically. Copy the URL to share the exact calculation with anyone.
How accurate are the results?
All calculations are rounded to 2 decimal places for clarity. The formulas use verified equations from CDC and WHO guidelines.
What safety precautions should I take when mixing bleach?
Always add bleach to water, never water to bleach. Work in a well-ventilated area. Wear gloves and eye protection. Never mix bleach with ammonia, vinegar, or other cleaning products as this produces toxic chlorine gas.
What does the chart show?
The bar chart displays the calculated volumes for comparison. The pie chart shows the relative distribution of bleach and water in the final mixture.
