Drain cleaning powder unblocker for sinks, basins, toilets and bath drains, 240g multi-use drain cleaner with sodium hydroxide formula and aluminium powder reaction for effective clog removal in household plumbing
240g Drain Cleaning Powder with Sodium Hydroxide for Sinks, Basins, Toilets and Bath Drains

This 240g drain cleaning powder provides a practical solution for common household plumbing blockages across multiple fixture types. The formulation combines sodium hydroxide with aluminium powder to create a chemical reaction that helps break down organic matter like hair, food particles, and soap scum. Packaged as eight individual 30g portions, it offers controlled application for different drain sizes and blockage severities. With additional components including sodium hypochlorite and sodium dodecyl benzene sulfonate, the powder works to penetrate and clear clogs in kitchen and bathroom drainage systems without requiring specialist tools or professional intervention.
Features and Construction
The drain cleaner uses a chemical-based approach rather than mechanical or enzymatic methods. Each component serves a specific function in the unblocking process, with the combination designed to address various common household drainage issues.
Material and Build
Sodium hydroxide serves as the primary cleaning agent, working to break down organic materials that cause blockages. Aluminium powder creates a reaction when combined with water and sodium hydroxide, generating heat and gas that helps dislodge stubborn clogs. Sodium hypochlorite adds cleaning power to the mixture, while sodium dodecyl benzene sulfonate acts as a surfactant to improve penetration into blockage materials. The formulation is supplied as a dry powder rather than a liquid or gel.
Size and Practical Fit
The 240g total weight provides multiple applications across different drains in a household. The division into eight 30g portions allows users to apply appropriate amounts based on drain size and blockage severity. Smaller portions suit basin and sink drains, while combining portions may be appropriate for larger toilet or main drain applications. The powder format facilitates storage without liquid spillage concerns.
Uses and Placement
This drain cleaning powder addresses blockages in standard domestic plumbing systems. It suits various fixture types commonly found in households and requires no specialised equipment for application.
Event or Professional Use
The multi-portion packaging makes it suitable for regular maintenance in settings requiring frequent drain attention, such as rental properties, offices with kitchen facilities, or hospitality environments. The chemical reaction approach can address accumulated blockages that develop over time in frequently used drains. The standard type 0 formulation provides general-purpose cleaning without specific adaptations for unusual plumbing materials.
Everyday Home Use
For domestic applications, the powder works on kitchen sinks where food particles and grease accumulate, bathroom basins with toothpaste and soap residue, toilets with organic waste buildup, and bath or shower drains collecting hair and soap scum. The eight portions provide multiple treatments across different drains within a home, addressing blockages as they occur without requiring immediate purchase of additional product.
Benefits and Buying Value
The product offers practical advantages through its formulation and packaging. These benefits focus on functionality rather than aesthetic or premium claims.
Reuse and Low Maintenance
The eight-portioned design extends usability across multiple drain treatments, potentially addressing several blockages over time from a single purchase. Dry powder storage reduces concerns about container integrity or product degradation compared to some liquid alternatives. The formulation works without requiring specialised tools, electrical devices, or manual drain snakes for most applications.
Why Choose This Product
This drain cleaning powder provides a chemical-based solution for households experiencing common drainage issues. The sodium hydroxide and aluminium powder combination creates a reaction that can address stubborn organic blockages. Multi-portion packaging offers flexibility for treating different drain types and sizes. The inclusion of sodium hypochlorite and a surfactant enhances cleaning action and penetration into clog materials.
