1. Hydrochloric Acid (HCl)
Description:
A clear, highly corrosive, strong mineral acid with a pungent smell. It is a major component of stomach acid and has wide industrial use.
Applications:
Used for descaling boilers and heat exchangers
Removes rust and scale from steel surfaces
Essential in the production of chlorides, fertilizers, and dyes
Used in pH control and water treatment processes
Caution: Highly corrosive to skin and metals; requires proper PPE during use.
2. Sodium Hydroxide (NaOH) (Caustic Soda)
Description:
A strong alkaline compound in solid (pellets/flakes) or liquid form. It’s highly reactive with acids and organic materials.
Applications:
Used in degreasing and removing organic matter from machinery
Neutralizes acidic contaminants
Key ingredient in soap making and chemical manufacturing
Commonly used in drain cleaners and metal processing
Safety Note: Can cause severe chemical burns. Requires careful handling.
3. Chlorine-Based Cleaners
Description:
These cleaners contain chlorine compounds such as sodium hypochlorite (bleach) or calcium hypochlorite. Known for their strong oxidizing and disinfecting properties.
Applications:
Powerful disinfectants for industrial and sanitation use
Effective against bacteria, viruses, and fungi
Used in water treatment, surface cleaning, and mold removal
Common in swimming pool maintenance and food processing facilities
Note: Strong fumes; should never be mixed with ammonia.
4. Hydrogen Peroxide (H₂O₂)
Description:
A clear, odorless liquid with strong oxidizing properties. Available in different concentrations, from 3% (medical) to 35%+ (industrial use).
Applications:
Used as a bleaching and disinfecting agent
Effective in removing biological and organic stains
Breaks down into water and oxygen — eco-friendly
Used in textile, paper, and electronics industries
Note: Stabilizers often added for storage; high concentrations are hazardous.
5. Citric Acid (C₆H₈O₇)
Description:
A weak organic acid naturally found in citrus fruits. Biodegradable and non-toxic, making it ideal for food-safe and eco-friendly cleaning.
Applications:
Descaler for kettles, coffee machines, and industrial boilers
Removes limescale and hard water deposits
Used in pharmaceutical and cosmetic industries
Mild enough for household use but effective in industrial formulas
