Drain cleaning powder unblocker for kitchen sinks, bathroom basins, and shower drains, 120g capacity formula with sodium hydroxide and active foam action to tackle grease and hair clogs.
120g Drain Cleaning Powder for Sinks, Basins, and Shower Drain Blockages

Facing a slow-draining kitchen sink or a completely blocked bathroom basin can disrupt daily routines. This drain cleaning powder provides a chemical-based solution designed to tackle such common household plumbing issues. The 120g formulation utilises a combination of active ingredients, including sodium hydroxide and foam-generating agents, to help break down obstructions caused by accumulated grease, food particles, soap scum, and hair. It is intended for use in standard domestic drain openings where mechanical clearing methods are not preferred or available.
Features and Construction

This product is constructed as a dry, granular chemical powder supplied in a single container. Its design focuses on a reactive chemical process to address blockages rather than physical removal. The key to its function lies in the specific blend of compounds contained within the powder, each serving a distinct role in the unblocking process.
Material and Build
The core active material is sodium hydroxide, commonly known as caustic soda. This strong alkali works to hydrolyse fats and greases, converting them into soap-like substances that are more soluble in water. The formulation is augmented with aluminium powder and sodium hypochlorite. When combined with water, these ingredients react to generate heat and a vigorous foam. This foam expansion helps to push through and dislodge debris further down the pipe. Sodium dodecyl benzene sulfonate is included as a surfactant to enhance the wetting and foaming action of the mixture.
Size and Practical Fit
The product is offered in a single size option with a 120g capacity. This quantity is suitable for addressing a typical single drain blockage event in a domestic setting, such as a kitchen sink or bathroom basin. The granular powder format allows it to be poured directly into the drain opening, ensuring the chemicals are concentrated at the site of the blockage. The container size is practical for household storage and for use as an on-demand solution when a blockage first becomes apparent.
Uses and Placement

This drain cleaner is formulated for specific types of blockages and should be used accordingly. Its chemical action is most effective on organic and fatty deposits that are susceptible to alkali attack and foam displacement. Understanding its intended applications helps ensure it is used effectively and safely.
Event or Professional Use
For severe or recurrent blockages, or in commercial settings, professional mechanical drain cleaning is often recommended. This powder is positioned as a first-response or maintenance product for domestic users. It can be used as part of routine drain maintenance to help prevent full blockages from forming, or to address minor slow-draining issues before they escalate. It is not a substitute for a plumber's snake or high-pressure jetting in cases of solid object obstructions or deeply set blockages.
Everyday Home Use
The primary everyday use is for clearing blockages in standard household plumbing fixtures. This includes kitchen sinks where grease and food waste accumulate, bathroom washbasins clogged with hair and soap, and shower or bath drains affected by hair and soap residue. The product should only be used in drains that are in good condition and can tolerate chemical cleaners, and it is crucial to follow the usage instructions provided on the packaging regarding water addition and safety precautions.
Benefits and Buying Value

The value of this product lies in its convenience and targeted action for specific domestic problems. It offers an alternative to manual plunging or disassembly of plumbing traps, which can be messy and require more tools. The benefits are tied directly to its formulation and format.
Reuse and Low Maintenance
The 120g container is intended for use as a complete treatment for one blockage incident. It is a consumable product, so 'reuse' refers to having it available on hand for future blockage events in the home. Its low maintenance aspect comes from the simple application process—no tools are required beyond the product itself and water. Proper storage in a cool, dry place, away from moisture, ensures the powder remains effective until needed.
Why Choose This Product
Choose this drain cleaning powder if you require a chemical-based solution for common organic drain blockages in your home. Its value is in the specific formulation of sodium hydroxide combined with active foam-generating agents (aluminium powder and sodium hypochlorite) designed to tackle both grease and dislodge debris. The 120g size provides a sufficient quantity for a standard treatment, making it a practical single-purchase item to keep in your cleaning cupboard for addressing slow drains in sinks, basins, and showers.
