Washing machine cleaning tablet 12 pack with sodium bicarbonate and citric acid for automatic washing machines, designed to remove limescale and detergent residue from the drum and pipes.
Washing Machine Cleaning Tablets 12-Pack with Sodium Bicarbonate Formula

Regular cleaning is essential for maintaining the performance and hygiene of your automatic washing machine. Over time, limescale from hard water and residual detergent can accumulate inside the drum, dispenser drawer, and internal pipes. This 12-pack of washing machine cleaning tablets is formulated to address these common issues without harsh chemicals. Each tablet combines sodium bicarbonate and citric acid to help dissolve mineral deposits and organic matter, while other ingredients work to lift and flush away residue. Using these tablets as part of a routine maintenance schedule can help ensure your machine runs efficiently and remains odour-free.
Features and Construction
This product is a set of pre-portioned cleaning tablets designed specifically for automatic washing machines. The formulation is built around practical cleaning chemistry rather than abrasive or corrosive agents.
Material and Build
The active ingredients are sodium bicarbonate, a common gentle abrasive and cleaning agent, and citric acid, which is effective at breaking down limescale. Sodium dodecyl sulfate acts as a surfactant to enhance the cleaning action by reducing surface tension. The inclusion of 1,2-hexanediol serves as a solvent and humectant, while EDTA-2Na is a chelating agent that binds to metal ions present in hard water deposits. Together, these components create a formula aimed at dissolving and removing buildup without damaging the machine's internal components.
Size and Practical Fit
The product is supplied as a pack of 12 individual cleaning sheets or tablets. No specific dimensions, weight, or individual tablet coverage area are detailed in the provided information. The pack size allows for multiple cleaning cycles over an extended period, fitting conveniently into a household cleaning cupboard. Each tablet is designed to be used singly per cleaning cycle in a standard domestic automatic washing machine.
Uses and Placement
These tablets have a single, clear primary use case: cleaning the interior of automatic washing machines. They are not designed for other appliances or surfaces.
Event or Professional Use
For settings like laundrettes, rental properties, or large households with high-frequency machine use, regular descaling and cleaning are crucial to prevent malfunctions and maintain hygiene. A 12-pack provides a cost-effective supply for scheduled professional maintenance. The formulation is suitable for machines that experience heavy use and consequent accelerated buildup of soap scum and limescale.
Everyday Home Use
In a typical home, using one tablet every month or in accordance with your machine's manual can help manage gradual limescale accumulation and prevent musty odours caused by mould and bacteria in damp residue. The tablets offer a convenient, pre-measured alternative to liquid cleaners or homemade mixtures, simplifying the maintenance task for the user.
Benefits and Buying Value
The value of this product lies in its role as a preventative maintenance tool for an essential household appliance, potentially extending its operational life and efficiency.
Reuse and Low Maintenance
The 12-tablet pack provides multiple uses, encouraging regular maintenance. The product itself requires no special storage or handling instructions beyond keeping it in a dry place. Using the tablets as directed involves minimal user effort—simply placing one in the drum and running a cycle—which supports consistent use.
Why Choose This Product
This product offers a specific formulation containing sodium bicarbonate and citric acid, ingredients known for their descaling properties. The pack of 12 represents a practical quantity for ongoing maintenance. It provides a straightforward solution for a common household need without requiring the user to mix or measure cleaning agents. The focus is on the practical removal of documented buildup types (limescale and detergent residue) using a stated blend of ingredients.
