Cleaning Chemical Dilution Chart – How Much Product Do I Need to Add?

This dilution chart from RapidClean Illawarra (trading online as Rapid Supplies) helps you work out how much concentrated cleaning chemical to add to water for common mix rates – from 1:1 through to 1:800 – in 500 mL, 1 L and 10 L containers.

Always follow the dilution rate printed on the product label and Safety Data Sheet (SDS). This chart is a general guide only and assumes a total ready-to-use volume of 500 mL, 1 L or 10 L.

Cleaning chemical dilution rates by ratio and percentage, showing how many millilitres of chemical and water to use for 500 mL, 1 L and 10 L of ready-to-use solution.

Safe Chemical Handling & Best Practice

Always add water first and then chemical to avoid splashes of concentrate, and follow all chemical handling guidelines. Wear gloves, goggles and other personal protective equipment (PPE) as required.

Read and understand the Safety Data Sheet (SDS) and Product Information Sheet for your chemicals before use, and follow the dilution instructions on the label.

For sites that need consistent dosing across multiple areas, consider using a chemical dispensing system such as SEKO ProMax to automate dilution and reduce handling: SEKO ProMax Chemical Dispensing Systems – Safe Chemical Dilution
