Effective and safe cleaning largely depends on the type of product used and its pH level. Cleaning products are classified into three main categories based on their pH: alkaline, acidic, and neutral. Each type has specific properties that make them suitable for different applications. Below, we will explore the different types of cleaning based on pH and how to choose the right one for each need.
Alkaline cleaning
Definition and properties
Alkaline cleaning products have a pH greater than 7. They are multifunctional and stand out for their ability to break down, solubilise, and saponify organic compounds, especially fats and proteins. These products hydrolyse triglycerides and react with fatty acids to form soluble soaps.
Applications
- Kitchens and restaurants: Ideal for cleaning surfaces where fats and food residues accumulate.
- Food industry: Used for degreasing equipment and surfaces.
- Households: Effective in cleaning ovens, grills, and kitchen extractors.
Benefits
- Effective removal of fats and proteins: Their ability to saponify fats and proteins makes them extremely effective in areas where these compounds accumulate.
- Versatility: They can be used in a variety of settings, from domestic to industrial.
Acidic cleaning
Definition and properties
Acidic cleaning products have a pH below 7. They are necessary for breaking down and mineralising inorganic deposits, often resulting from high water hardness or various types of mineral contamination. Generally, acidic products are applied after alkaline cleaning to ensure a thorough clean.
Applications
- Bathrooms and sanitary areas: Ideal for removing lime scale and calcium deposits.
- Food industry: Used to descale equipment and surfaces.
- Metal cleaning: Effective for removing rust and other mineral deposits.
Benefits
- Effective in removing mineral deposits: They efficiently break down inorganic scale, improving the appearance and functionality of surfaces.
- Complementary to alkaline cleaning: They ensure a complete clean after alkaline treatment, especially in industrial environments.
Neutral cleaning
Definition and properties
Neutral cleaning products have a pH close to 7. They are gentle and safe for most surfaces and materials, making them ideal for daily use and general cleaning.
Applications
- Households: Suitable for cleaning delicate surfaces such as wooden floors, furniture, and countertops.
- Offices: Used for cleaning desks, screens, and electronic equipment.
- Healthcare settings: Safe for cleaning surfaces in hospitals and clinics.
Benefits
- Safety: They are safe for most surfaces and materials, reducing the risk of damage.
- Daily use: Ideal for regular cleaning and maintaining daily hygiene.
How to choose the right cleaning product
- Identify the type of dirt: Determine whether you need to remove fats and proteins (alkaline products), mineral deposits (acidic products), or carry out general cleaning (neutral products).
- Consider the surface: Ensure that the product's pH is safe for the surface you are cleaning. For example, acidic products can damage marble or limestone surfaces.
- Frequency of use: For daily cleaning, neutral products are generally the best option. For deeper and more specific cleans, consider alkaline or acidic products depending on the need.
- Compliance with regulations: Make sure the products comply with local regulations and safety standards.
Conclusion
Understanding the different types of cleaning products based on their pH helps in selecting the right product for each task. Alkaline products are ideal for removing fats and proteins, acidic products are necessary for breaking down mineral deposits, and neutral products are perfect for daily cleaning and delicate surfaces. By choosing the correct product, you ensure more effective and safe cleaning, protecting both the surfaces and the health of users.
Implementing a pH-based cleaning routine not only improves cleaning effectiveness but also optimises product use and protects treated surfaces. If you are looking for specific and effective cleaning solutions, consider the appropriate products according to their pH to achieve the best results.
