CLEANING CHEMICALS AND PH, 10 MUST KNOW FACTS

PH, what is PH

Chemicals and their Ph are defined on the PH scale. The pH scale is a measure from zero to 14. It reflects the relative amount of free hydrogen and hydroxyl ions in the water – the more hydrogen ions, the more acidic the product, the greater the number of hydroxyl ions, the more alkaline the product. 

Acid products have a low PH and alkaline product have a high PH. The middle number on the scale, 7, is used to describe substances that are neutral in acidity – for example pure water. Any number on the scale below 7 is acidic, any number above 7 is considered alkaline. Acidic substances are great for removing calcium, rust and minerals while alkaline solutions are much more effective at cutting through grease, proteins, oils, dirt and organic items

How do everyday items fit in the PH Scale

Lets define the types of Cleaning Chemicals and their PH

• Acidic Agents 

Acidic cleaners usually have mineral acids (like hydrochloric acid) as the active ingredient. They are used to brighten metals or remove mineral deposits and clean oxidized materials. Many bathroom fixture cleaners are acidic, and their purpose is to remove calcium build-ups (water stains/lime deposits) or scaly or corrosive deposits. 

• Alkaline Agents 

Alkaline cleaners, like degreasers and ammonia, are used to dissolve fats, oils and proteins. Most types soils will contain these elements and alkaline cleaning agents will break down these materials and make them easier to remove. 

• Neutral Agents 

Neutral cleaning agents are called such due to their pH-neutral base. They are useful for dispersing dirt, dust and other debris though a completely neutral base. They will have less cleaning effect than a cleaning agent that falls more to one side of the scale, and are ideal for light soil loads. 

So what are the typical PH values of chemicals ..

• Chlorine bleach
Chlorine Bleach has a pH of between 11 and 13. As an alkaline product it makes a fantastic whitening and stains removal agent. However it is fairly corrosive. This means it’s great for every hard surface, but you need proper ventilation when using it and be careful on materials and clothes 

• Ammonia
Ammonia solutions have a pH of between 11 and 12. Highly alkaline substance, ammonia is a formidable cleaner that can work miracles in removing dirt and grime. Use with proper protective equipment in an area that provides adequate ventilation. 

• Mild dish detergent
Mild dishwash detergents have a pH of between 7 and 8 .If you’re using dish detergent that’s labelled ‘mild’ this generally means its pH level is sitting just around the middle, which is perfect for items you’re cleaning on a daily basis. Most surfaces won’t be damaged by mild dish soap and you generally don’t need to wear protection when dealing with products of a neutral acidity. 

• Vinegar
Vinegar has a pH of around 3.The acidic properties in vinegar make it perfect for removing tough mineral deposits, but it also makes it a bad choice for some surfaces (particularly stone). Vinegar also has the potential to cause real damage if you’re not careful. Protection for your face and hands is a definite must. 

• Toilet bowl cleaner
Toilet Bowl cleaner has a pH of between 1 and 3. Toilet bowl cleaners are extremely acidic but perfect for breaking down minerals and other non-organic nasties that might be lurking in your toilet bowl. You must use these products with extreme caution. 

What chemical and PH should I use for cleaning

For acid-based soils, such as those listed below, use cleaning chemicals with and alkali PH.

• Greasy floor
• Dirty walls
• Cigarette tars
• Engines and tools
• Motor oils, diesel oil, axle grease Cooking oil
• Ventilation hoods
• Ovens

For alkaline-based soils, such as those listed below, use cleaning chemicals with an acid PH.
