"Our family hasn't bought dish-washing soap in twenty years." All the dishes or anything that needs cleaning can be washed in hand soap, because the basic ingredient in soap is plant or animal fat, and even if it's phosphate-free dishwashing liquid, it still includes perfumes and artificial coloring. Long-term contact is harmful to people's health.
「我們家已經廿年沒買過洗潔精」，所有碗盤，需要清洗的東西都用肥皂來洗，因為肥皂的原料是天然動植物油脂，而即使是不含磷酸鹽的洗淨劑，仍然含有色素和香料，接觸久了，對人體有害。
