A formulation for creating a cleaning agent intended for use in washing machines, this typically involves combining soap (often in flake or grated form), washing soda (sodium carbonate), and borax (sodium borate). The proportions of these ingredients can vary, resulting in differing levels of cleaning power and suitability for various fabric types and water hardness levels.
Such preparations offer several advantages, including cost-effectiveness compared to commercially produced detergents, control over ingredients to avoid potential allergens or harsh chemicals, and a reduced environmental impact by minimizing packaging waste. Historically, homemade laundry solutions were common before the widespread availability of manufactured detergents, relying on readily accessible ingredients and providing a practical solution for household cleaning needs.
