Guidelines for Safely Diluting Concentrated Cleaning Chemicals

Concentrated cleaning chemicals are effective cleaning agents - but only when used correctly. 

These chemicals are often dangerous and need to be stored, handled and diluted safely. 

You should always refer to the manufacturer’s guidance when diluting Concentrated Cleaning Chemicals. Never mix cleaning chemicals with water or any other substance, unless you are instructed to do so by manufacturer instructions.

We’ve compiled this guide to help cleaning professionals and housekeepers safely dilute concentrated cleaning chemicals. This information will help you and your team understand the importance of safety measures and correct dilution procedures. 

Anyone who handles cleaning chemicals must wear appropriate Personal Protective Equipment (PPE) and always handle these potent chemicals with the utmost care. 

Standard Operating Procedure (SOP) for Diluting Concentrated Cleaning Chemicals Safely

Purpose: This SOP outlines a general procedure for safely diluting concentrated cleaning chemicals, essential for maintaining household cleaning standards.. This guideline protects cleaning professionals by minimising the risks of handling and diluting these chemicals. This is not a substitute for manufacturer guidance and instructions. Always refer to the manufacturer's information first. This is a supporting guide to ensure safety.


  1. Prepare Protective Equipment: Wear appropriate personal protective equipment (PPE). This includes gloves, eye protection, and clothing that covers the skin to avoid direct contact with the concentrated chemical.
  2. Ventilation: Ensure the workspace is well-ventilated to disperse any fumes that may be produced during dilution.
  3. Choose an Appropriate Container: Select a clean, chemical-resistant container that is large enough to hold the final volume of the diluted solution. The container should have clear measurement markings.
  4. Fill with Water First: Always add water to the container first. This is crucial to avoid a violent reaction when water is added to certain concentrated chemicals.
  5. Add Concentrated Chemical: Slowly add the appropriate amount of concentrated chemical to the water. Follow the manufacturer's dilution guidelines to ensure the correct concentration.
  6. Mix Solution: Stir the solution gently until it is thoroughly mixed. Do not shake the container, which could lead to splashing or releasing volatile fumes.
  7. Label the Container: Label the container clearly with the name of the chemical, its concentration, the date of dilution, and any safety precautions.
  8. Storage and Disposal: Store the diluted chemical in a cool, dry place out of direct sunlight. Dispose of any waste materials as per local regulations and guidelines.

Safety Precautions: Always follow the specific safety instructions provided by the cleaning chemical manufacturer. In case of skin or eye contact, rinse immediately with plenty of water and seek medical advice.

Accountability: It is the responsibility of all cleaning professionals to follow this SOP when diluting concentrated cleaning chemicals. Supervisors should ensure that these procedures are understood and adhered to.

Essential Equipment for Safely Diluting Concentrated Cleaning Chemicals

Personal Protective Equipment (PPE)

Gloves: A pair of chemical-resistant gloves is indispensable to protect your hands from direct contact with concentrated chemicals. These prevent skin irritation and chemical burns that can occur from such exposure.

Eye Protection: Safety glasses or goggles shield your eyes from potential chemical splashes. Considering that some chemicals can cause severe eye damage or blindness upon contact, this is crucial to your PPE.

Coveralls or Aprons: Wearing a chemical-resistant apron or coverall can protect your clothes and skin from accidental spills or splashes during dilution.

Footwear: Chemical-resistant boots ensure that any spills do not harm your feet or lower legs.

Tools and Containers

Chemical-Resistant Container: This is where you will perform the dilution. The container must be resistant to the chemical you're diluting, have clear measurement markings, and be large enough to hold the final volume of the diluted solution.

Measuring Equipment: You'll need measuring cups or a chemical dispensing system to achieve the correct concentration. Accurate measurements are essential to ensure the efficacy and safety of the diluted chemical solution.

Stirring Tool: A long, chemical-resistant stirring rod or spoon is used to mix the solution. Avoid shaking the container to prevent splashes or the release of volatile fumes.

Labelling Equipment: Use permanent markers and chemical-resistant labels to clearly mark the container with the chemical name, dilution date, concentration, and safety precautions. Proper labelling is crucial for safety and regulatory compliance.

Ensuring Safety When Diluting Concentrated Cleaning Chemicals

Maintaining a safe, efficient dilution process requires adherence to certain crucial principles.


Use PPE: Always equip yourself with the necessary Personal Protective Equipment (PPE) before starting the dilution process.

Ventilate: Ensure your workspace is adequately ventilated to disperse potentially harmful fumes.

Measure Accurately: Precise measurements are key to achieving the correct concentration for effective and safe cleaning.

Add Water First: This prevents violent chemical reactions that can occur when water is added to concentrated chemicals.

Label Containers: Properly label all containers with the name of the chemical, its concentration, the dilution date, and safety precautions.

Store Safely: Store the diluted solutions in a cool, dry place away from direct sunlight, ideally in a secure, ventilated cabinet.


Mix Different Chemicals: Mixing different chemicals can lead to harmful reactions. Always dilute each chemical separately and use as directed.

Overlook Safety: Never overlook or underestimate the importance of safety measures, even if the task seems routine.

Rush: Haste can lead to accidents like spills or incorrect concentrations. Always take your time during the dilution process.

Improperly Dispose of Chemicals: Follow local regulations for disposing of any leftover concentrated chemicals or waste materials.

Leave Chemicals Unattended: Never leave concentrated or diluted chemicals unattended.

Before using any cleaning chemicals on surfaces, it is essential to carefully read and adhere to the manufacturer’s instructions provided on the product packaging and on the Safety Data Sheet. Failure to do so could lead to unintended consequences, including damage to surfaces, health risks, or inefficient cleaning. The instructions outline proper usage, dilution ratios, safety precautions, and compatibility with different materials.
