For difficult stains (such as food), think of quickly treating your cotton garments before washing. To do so, apply some Marseille soap or a mild stain remover directly to the affected area and rub gently. Let sit for a few minutes, then wash as usual. This quick preventive measure will help preserve the quality and color of your cottons well into the future.
For long-lasting care, keep tumble-drying to a minimum. Among other things, drying cottons in the dryer can make your garments shrink, lose their shape, or become damaged. If you really need to tumble-dry, use a low-temperature or delicate cycle.
Once they are dry, store your cotton garments in a clean, dry closet or drawer protected from moisture to prevent mildew and unwanted odors.
