What is caustic soda?
Caustic soda is the common name for sodium hydroxide (NaOH). It’s a highly alkaline substance that dissolves in water to form a strongly caustic solution. It’s used where you need powerful cleaning, degreasing, neutralisation or pH control. Because it can cause severe burns, it’s typically supplied for professional and industrial use with appropriate safety documentation.
Key Applications
This versatile chemical is essential for a wide range of demanding tasks:
- Professional Paint Stripping: Highly effective at breaking down and removing aged oil-based paints and varnishes from masonry, stone, and metal surfaces.
- Industrial Degreasing: Quickly dissolves fats, oils, and grease from heavy machinery, concrete floors, and workshop equipment.
- Drain & Pipe Maintenance: An aggressive solution for clearing organic blockages, hair, and fat deposits in commercial drainage systems.
- Sanitization & Cleaning: Used in various industrial processes for pH regulation and deep-cleaning protocols.
Please note: this product can only be used for professional and industrial applications.

Important Usage & Safety Information
Caustic Soda is a highly corrosive substance. To ensure safe and effective use, please adhere to the following guidelines:
Mixing Instructions
Always follow the “Chemical to Water” rule. Never pour water onto Caustic Soda pearls, as this can cause a violent “spit-back” reaction. Instead, slowly add the pearls to a measured volume of cold water while stirring gently.
Recommended PPE
Due to its corrosive nature, the following Personal Protective Equipment is mandatory:
Chemical-resistant gloves (Nitrile or PVC).
Impact-resistant safety goggles or a full face shield.
Protective overalls and sturdy, closed-toe footwear.
Surface Compatibility
Do Not Use on Aluminum: This product reacts violently with aluminum, zinc, and galvanized surfaces.
Wood Surfaces: Use caution on wood as it can darken the grain and weaken the fibers if not neutralized correctly with a mild acid (like white vinegar) afterward.
Storage & Handling
Keep the container tightly closed and store in a cool, dry, well-ventilated area. Sodium Hydroxide is hygroscopic, meaning it will absorb moisture from the air and solidify if left exposed. Keep out of reach of children and unauthorized personnel.
Q:Is caustic soda the same as sodium hydroxide?
A:Yes, caustic soda is the common name for sodium hydroxide (NaOH).
Q:What is caustic soda used for?
A:It’s used for heavy-duty cleaning/degreasing, drain maintenance (where appropriate), stripping, and various industrial processing tasks including pH adjustment.
Q:How do I dilute caustic soda safely?
A:Use suitable PPE and a compatible container, and add caustic soda to water slowly (not the other way round). Mix carefully because the solution can heat up.
Q:Is it suitable for household drains?
A:Yes, it is highly effective for clearing fat and grease blockages, but must be used with extreme caution.
Q:Is it safe on metal or plastic?
A:It can attack aluminium and may affect some metals and plastics. Always check material compatibility and test on a small area first.
Q:How should I store caustic soda?
A:Keep dry in an airtight container and away from moisture in a cool, secure place. Store out of reach of children.
Q:Do you provide an SDS (Safety Data Sheet)?
A:Yes, an SDS is available on request (and/or with the product documentation, depending on your process).
