One of the most troublesome dirt when washing dishes and cooking utensils is "oil stains."Some people may be in trouble to drop.
This article introduces how to efficiently remove oil stains on tableware and cooking utensils.
油が多く付いた食器や調理器具はどう洗えばいい？目次Oil stains on tableware and cooking utensils have the characteristics of "hard to dissolve in water" and "acidic".
As the saying is "water and oil", there is basically no mix between water and oil.Therefore, oil stains cannot be washed off with water alone.
However, if you intervene a substance linked to both the water and the oil, you will be able to connect the oil to the substance and flush it into the water.Two types of substances linked to both water and oil are known, "emulsifiers" and "surfactants", but dishwashing detergents make it easier to remove oil stains by blending the latter.
本来、水分と油分は混じり合うことはありません。食器用洗剤は、両者を結び付ける「界面活性剤」を配合することで油汚れを落としやすくしますScientific substances are largely divided into "acidic", "neutral", and "alkalinity" by the large and small pH (PEichi / Payha: hydrogen ion index).Speaking of science classes, pH7 (median) is neutral, those less than that are acidic, and those exceeding that are classified as alkaline.
However, in Japan, the "Household Supplies Quality Labeling Law", which sets the quality standards of various detergents, is classified as follows.
Following the chemical reaction providence, acidic dirt can easily fall off by "neutralization" with an alkaline detergent.This is the same for dishwashing, and oil stains (acidic dirt) attached to tableware and cooking utensils can easily fall off with (weak) alkaline detergent.
When removing the oil stains of tableware and cooking utensils, some people say that they use more detergents than usual and use a lot of water to drain dirt and detergent, but with a detergent used by a little device.It will save water.
Oil stains are difficult to remove when they cool.In particular, the tendency of "fat" from meat is remarkable.Wash dishes and cooking utensils as soon as possible (while warm).
It is also recommended to wash with lukewarm water if possible.
特に肉類の脂は、冷えてしまうと落としにくくなってしまいます。なるべく早く洗うようにしましょうOil dirt can reduce the amount of detergent used by wiping it with kitchen paper or worn -out newspaper before washing.As a result, the amount of water when washing the detergent can be reduced.
新聞紙やキッチンペーパーで拭いてから洗うと洗剤や洗い流す水の量を減らせますThe "order" of washing dishes and cooking utensils is also surprisingly important.Some people may be washed from dishes and cooking utensils with oil -stuck in some people because they feel better because they feel better from terrible dirt.However, if you wash from a lot of dirt containing oil, the cleaning ingredient of the detergent (including surfactants) will be exhausted, and what will be washed later will "move".is.
If you wash multiple dishes and cooking utensils at once, wash them in order from less dirt.By doing so, the total amount of detergent used can be reduced.As a result, the amount of water when washing the detergent can be reduced.
If you try to wipe it with the kitchen paper (or newspaper) mentioned above, you can save more.
汚れの少ないものから順に洗うようにしましょうAs mentioned earlier, if you wash the dishes and cooking utensils with terrible oil stains first, the dirt may transfer.If possible, we recommend that you prepare a separate sponge for dishes and cooking utensils with severe dirt.
If you can, you may want to prepare an optimized one (≒ foam easily stands) if possible.Note, however, that the frequent foaming of the detergent and the removal of oil stains are not necessarily equal (it depends greatly on the nature / composition rate and liquidness of the surfactant used).
In order to efficiently remove oil stains, we recommend using a (weak) alkaline and a highly compounding rate of surfactants.
However, detergents with strong alkaline tend to have a large effect on the skin.If you have a weak skin, you may want to use gloves when washing or use neutral detergents that tend to have less effect on the skin.
Here are some recommended detergents for oil stains, including automatic dishwasher (dishwasher), so please refer to them (including neutral detergents).
