Our advice in case of stains
↳ If watery stain:
Mix a few teaspoons of baking soda (depending on the size of the stain) with a splash of water. The whole thing should form a sort of somewhat solid paste; if there is too much water and it doesn't mix very well, don't hesitate to add a little bicarbonate. You can add a little of your laundry detergent which helps bind the mixture.
Spread the mixture directly on the stains so as to cover them completely.
Leave it on for 20-30 minutes then gently scrub the stained areas with a clothes brush or an old toothbrush.
Rinse with clean water then let air dry.
Otherwise Marseille soap also works. You can buy stain remover bars which are generally gray in color. Moisten the bar, rub circularly for 5-10. Leave on for 15-20 minutes then always rinse with cold water if it is a watery stain.
↳ If greasy stain:
Take some dishwashing liquid, put a drop on the stain and rinse with hot water.
