Caustic Soda Pearls 99% Pure – Heavy-Duty Drain Unblocker & Cleaner

Caustic Soda Pearls 99% Pure – Heavy-Duty Drain Unblocker & Cleaner

In stock

Our High-Purity Caustic Soda Pearls are industrial-strength sodium hydroxide crystals engineered for extreme chemical unblocking, heavy-duty degreasing, and industrial surface stripping. Composed of premium-grade, free-flowing white pearls, this highly alkaline material rapidly dissolves organic blockages, emulsifies animal fats, and breaks down thick grease matrices that standard commercial cleaners cannot touch.

When dissolved in water, these powerful caustic soda pearls create a highly exothermic chemical reaction that actively melts fat, hair, soap scum, grease, and heavy organic silt. Its versatile, non-tainting formulation makes it an essential chemical agent for drain clearance, paint removal, commercial fat-trap maintenance, and agricultural equipment cleaning. Trusted across industrial engineering, contract plumbing, commercial catering facilities, and farm maintenance, it delivers maximum chemical stripping power while keeping maintenance costs exceptionally low.

Product features

💎 Premium High-Purity Pearls – Free-flowing solid sodium hydroxide crystal pearls dissolve rapidly and completely in water without leaving powdery residues or clumps behind.

🪠 Extreme Drain & Fat Trap Unblocker – Rapidly saponifies oils, melts human hair, dissolves soap scum, and vaporizes organic matter to clear completely blocked main lines and commercial fat traps.

🎨 Heavy-Duty Paint & Coating Stripper – When mixed into a concentrated solution, it acts as a fast-acting paint stripper that safely cuts through multiple layers of old varnishes, oil-based paints, and wood stains.

⚙️ Industrial & Agricultural Degreaser – Highly effective for stripping heavy grease layers from concrete workshop floors, industrial machinery parts, and livestock housing structures.

📦 High-Yield Economy Packaging – Solid raw chemical form offers maximum cost efficiency, enabling you to mix exact batch strengths tailored to your specific trade requirements.

Direction to use

📋 Commercial Application Guide:

  • For Heavy Drain Unblocking: Carefully dissolve 50g to 100g of Caustic Soda Pearls per 1 Litre of cold water. Mix thoroughly with a plastic stirrer until dissolved. Pour directly down the blocked drain or waste pipe. Allow 20 to 30 minutes contact time for the chemical reaction to melt organic blockages, then flush thoroughly with large volumes of fresh hot water. Repeat if necessary.
  • For Concrete Floor Degreasing & Heavy Cleaning: Dilute 20g to 50g of pearls per 1 Litre of cold water. Apply to the floor surface, scrub well using a stiff deck brush to break down oil crusts, allow 10 minutes dwell time, and rinse off thoroughly with fresh water.
  • For Paint Stripping Operations: Dissolve 100g to 150g of pearls per 1 Litre of cold water to create a highly active stripping solution. Apply carefully to old woodwork or metal surfaces with a brush. Allow the paint layer to wrinkle and soften, scrape off cleanly, and wash down the surface thoroughly with water to neutralize the wood.

⚠️ THE CRITICAL SAFETY MIXING RULE: Always add the Caustic Soda Pearls into cold water systematically in small increments. NEVER pour water directly onto raw caustic pearls. Mixing creates a strong exothermic reaction that generates significant heat and rapid steam bubbles; using hot water or adding water to the pearls can cause the solution to violently erupt and splash back at the operator.

Sizing and Availability

Standard Packaging: Supplied in heavy-duty, moisture-sealed security containers engineered to prevent atmospheric clumping and maximize chemical shelf life.

Liquid Conversion Note: Because this product is a raw solid crystalline pearl rather than a pre-mixed liquid, it is not compatible with standard 30ml liquid dosing pumps. Use dry trade weighing scoops or plastic measuring beakers to dispense exact solid weight metrics cleanly.

Bulk Trade Capacity: Fully stocked in professional trade capacities engineered for continuous high-frequency municipal cleaning, facilities restoration, and property maintenance.

Safety Information

🚨 Professional High-Strength Alkaline Crystals – Read full safety datasheets (SDS/MSDS) completely before trade handling. Contains pure Sodium Hydroxide (Solid). Highly corrosive.

  • Hazard Level: DANGER! May be corrosive to metals. Causes severe skin burns and serious eye damage.
  • Surface Compatibility Warning: ⚠️ DO NOT USE ON ALUMINIUM, ZINC, LEAD, TEFLON, OR GALVANISED FIXTURES. Caustic soda chemically reacts with these sensitive metals, producing heat and releasing highly flammable, dangerous hydrogen gas.
  • Protective Gear: Wear heavy-duty chemical-resistant gloves (nitrile or PVC), full wrap-around safety goggles, face shield, and chemical-resistant clothing during handling, weighing, and dilution.
  • First Aid Response:IF IN EYES: Rinse cautiously with fresh cold water for several minutes. Remove contact lenses if present and easy to do—continue rinsing. Immediately seek urgent medical attention.IF ON SKIN (or hair): Take off immediately all contaminated clothing. Wash skin thoroughly with running water or shower for at least 15 minutes. Seek immediate medical attention.IF SWALLOWED: Rinse mouth thoroughly. DO NOT induce vomiting. Drink plenty of fresh water or milk and seek immediate medical advice.
  • ⚠️ STORAGE INSTRUCTIONS: Store tightly sealed inside its original container in a cool, dry, locked cupboard or warehouse bay. Protect entirely from atmospheric moisture and damp environments, as humidity will cause the crystals to liquefy. Keep securely out of reach of children.
