Buying everyday products in 1L format can lighten your shopping load, prevent you running out of essentials, and reduce the cost per use. But a larger size doesn't always mean savings. An oil that's not right for your cooking, a highly concentrated cleaner, or a drink that lingers in the fridge for days can, in fact, end up in the bin.
Before you fill your basket, keep three pitfalls in mind:
Not all liquids sold in 1L format are used the same way. A 1L fruit juice, 1L semi-skimmed milk or a cooking oil are generally ready to drink or use straight away. On the other hand, Calpis Japanese syrup and some cleaning products need to be diluted.
The Asahi Calpis Concentrated Syrup 1L, for example, contains milk and soya and is prepared with water or milk. Its one-litre container therefore does not correspond to one litre of ready-to-drink beverage. To compare prices, take into account the actual volume you get after dilution.
The question of dosage also applies to products designed for appliances. The ECOVACS DEEBOT solution should be used at a ratio of 1:200. Using the product undiluted or replacing it with a household detergent can damage the appliance's internal system.
For food products, the size should never push essential information into the background:
Also keep an eye on the sugar content. Even without added sugars, a fruit juice contains those naturally present in the fruit. Tropicana apple juice, for instance, has 11g of sugar per 100ml, according to the information on the product. That's a much more useful figure for comparing different drinks.
An opened bottle doesn't keep indefinitely. Tropicana apple juice must be refrigerated after opening and consumed within five days. A NATRUE oat plant-based drink also needs to be kept chilled and drunk within a few days.
For household products, take the time to read the pictograms and usage precautions. A 1L drain cleaner containing caustic soda can cause severe burns. Wear gloves and safety goggles, ventilate the room, and never mix a drain cleaner with bleach, acid or any other cleaning product.
14° white vinegar also requires a degree of care. It is not suitable for marble, limestone, or porous or acid-sensitive surfaces. If in doubt, test it on a small, inconspicuous area first.

No. Compare the price per litre, but also the dosage, how long it keeps after opening, and how much you actually use. A bottle of concentrated cleaner can last much longer than a ready-to-use product, whereas an opened juice that you don't drink much of could end up being wasted.
Before opening, follow the instructions on the packaging. Once the bottle is open, generally place it in the fridge and stick to the recommended time frame. Seal it carefully and check its appearance, smell and the date shown before drinking.
No. Avoid any mixing, especially between a drain cleaner, bleach, white vinegar or an acid-based product. Dangerous fumes can be released. Use one product at a time, follow its label instructions and rinse as directed.
