Any grocer, pharmacy or general store will sell both liquid and powder detergents. But besides the price, how are you to decide which to buy? Both varieties work well, but the efficiency and eco-friendliness of each differs. As well, some machines work better with powders—especially older units—so you must consider the specifications of your washer.

Arguments for Liquid Detergent

Liquid detergents double as stain pre-treatments. You can soak soiled clothing hours before the wash for better results. This makes liquids more flexible and tougher on grease and oil stains. Because the detergent is a liquid, you never have to worry about residue either. You can dissolve it in any temperature.

Nevertheless, to transform detergent into liquid form, the product undergoes a longer manufacturing process. Consequently, it leaves a larger economic footprint. Likewise, people tend to use more liquid detergent than is necessary. Waste, too, contributes to a household’s footprint.

Chemically, liquid detergents contain more surfactants than powders. When released into the environment, these products are harsher on our ecosystems. Encapsulated liquids (i.e. gel packs) add to the chemical composition of the detergent.

Arguments for Powder Detergent

Many believe that powder detergents work better than liquids at removing everyday stains. For casual washing, it also costs less. Rather than coming in plastic bottles, some appreciate the eco-friendly cardboard box, too.

That said, some powders contain more chemicals overall. When used in excess, powders can clump and leave a chalky residue. This is especially true in cold water, where the powder cannot dissolve as effectively. However, as washing machines evolve and manufacturers change their recipes, residue will become less of a concern.
