Musou state in 100 "citric acid"?!3 cleaning places that can make the most of the characteristics

酸味成分として知られ、pH調整剤や酸味料といった食品添加物としても広く使われている「クエン酸」。

食品スーパーの製菓材料売り場などで粉状の商品を見かけますが、「100円ショップの洗剤売り場」にも置いてあること、ご存知でしたか？

In recent years, this "citric acid" has been handy as an acidic cleaning agent.This time, I will explain mainly how to use it in the cleaning field.

What is "citric acid"?

The "citric acid" "citric acid" is usually written, but the kanji "枸櫞" is the original.枸櫞 is an evergreen and low tree of the genus mandarin oranges, and has a fruit similar to lemon, but it is too sour to eat raw.

この枸櫞や檸檬を含む柑橘類に含まれる、代表的な酸のひとつが「クエン酸」です。

Industrially, citric acid can be made by fermenting starch and sugar in a kind of kojikabi.The refined citric acid looks white and have no smell.It has a very easy -to -soluble property (tide decomposition) and melts even when heated.Chemical C6H8O7 / H2O shows weakly acidic when dissolved in water.

This "citric acid" can be used not only for sour flavor but also for cleaning with the power of "acid".Like baking soda, it is not a "detergent" because it does not contain a surfactant, it is not a detergent, but a "cleaning agent", and leave it in one corner of your head.

What is the cleaning place where "citric acid" is active?

「クエン酸」の代表的な特徴（水に溶けやすい、弱酸性、においがない）を活かすことのできる、クエン酸と相性のいい代表的な掃除ポイントを３つご紹介します。

⒈ Sticked stains (bathroom, washroom, kitchen, etc.)

Our life and water (tap water) are always unavoidable, and water is an essential partner when cleaning after cooking.However, it is troublesome because this water itself can cause dirt in the house.

浴室の鏡やガラスドア、水栓金具、風呂椅子や洗面器、また洗面所の鏡、水栓、キッチンの水栓などといった箇所に、「白いカピカピした」「硬い」汚れが付くことがあります。これは「水垢」「スケール」「鱗状痕（りんじょうこん）」などと呼ばれる、水道水に含まれるミネラル成分。炭酸カルシウムや炭酸マグネシウムがこの汚れの正体です。

Because it is almost stone -like dirt, it cannot be easily removed with a normal surfactant or detergent.It is necessary to "dissolve" chemically.It is a relatively safe (food additive) acid "citric acid" that plays an active part there.Missed in water and is weakly acidic.In addition, it can be used in versatile by using a spray -shaped cleaning tool using the property that melts well in water.

水１カップに小さじ半分程度が希釈の目安です。空のスプレーボトルにこの水溶液を入れ、水垢（鱗状痕）が付いている部分に吹き付け、数分置いて水垢が溶けたところでペーパーやマイクロファイバークロスで拭き取ります。金属は錆びてしまうので必ず濯ぎ拭きを行うようにしましょう。

The advantage is that citric acid water has no smell.There is a method of using vinegar and grain vinegar for cleaning in the sense of using acid, but it is easy to use for people with unpleasant smells in the bathroom etc.

⒉ Ammonia odor (toilet, living room, bedroom, pet area, etc.)

Characteristic ammonia odor drifting from toilet bowls, toilet seats, floors, walls, etc.When living with a small child or pets, if you have a very unavoidable pee, you may be troubled in a living room such as a living room or a bedroom.

Ammonia is mainly caused by the decomposition of urea of the urine that spilled or scattered in the toilet, etc., but in recent years it has been found that it will drift from our body itself (fatigue odor).increase.You may have been soaked without knowing the living sofa or bedding, which is not particularly damaged by the crude phase.

このアンモニア臭を伴う箇所の掃除（ケア）にも、前述のクエン酸水スプレーを活用できます。クエン酸水は界面活性剤を含まないので汚れ落とし効果はマイルドですが、若干の剥離効果が見込めるのでこまめなトイレ掃除に使う際には、掃除効果プラス、アルカリ性のアンモニア臭を中和して消臭する効果があるため一手間でも一石二鳥なのです。

It is a fundamental response to the bedding, such as sofas that are worried about the ammonia odor, but as a connection until the day of washing, spraying citric acid spray and drying it.Can be reduced.

⒊ Rusted rust (bathroom, washroom, kitchen, etc.)

浴室や洗面所に、不用意に置いてしまったカミソリやヘアピン跡が茶色く残ってしまったり、キッチンなどで缶詰の空き缶を置いていた作業台などに丸い跡がついてしまい、容易に落とせなくなってしまった、という経験がある人、少なくないのではないかと思います。

この汚れは「もらい錆（さび）」と呼ばれます。あるもの（本来さびないもの）に対して他の金属が出した錆びが付着してしまうことで、一度もらい錆が付くと、通常の洗剤ではなかなか落とすことができなくなってしまいます。

A dedicated cleaner to remove rust is also available, but it is not very common.However, if you use citric acid, you can remove this dirt so that it is melted.

Put the citric acid (powder) on the rusted area to the extent to which the rust is covered and dissolve in a small amount of water.After leaving it for 20-30 minutes, sprinkle a small amount of cleanser (good powder, such as for kitchen), rub it off with a hard part of the brush or sponge, and rinse it firmly with water.

A place where citric acid is not suitable for cleaning

Citric acid has some parts that cannot be used for cleaning because of "acid".I want to make a mistake.

代表的なものが、玄関の三和土や床などに使用される「大理石」。美しいツヤが溶けて消されてしまい元に戻りません。

Stop using it for "iron" or "concrete".It may cause rust.

Surprisingly utilization of citric acid "melting slime"

子どものおもちゃであるスライム。これは、座布団やラグ、衣類などに付着してしまうと、柔らかいままでも、乾いてしまってもとても厄介な存在です。

しかしクエン酸を溶かした水でスライムごと溶かして落とすことができます。衣類など洗える素材の場合には、5％程度に希釈したクエン酸水に浸けて、スライムを緩め溶かし、洗濯板など用いてぬめる成分をこそげ落とします。

ラグや布団など洗いにくい素材に浸み込んだスライムは、クエン酸水に浸けたタオルを軽く絞ったものを被せて湿らせ柔らかくしたのち、このタオルを使ってやはりこそげるように拭き取ります。少し手間はかかりますが意外としっかり落ちるので、諦めずに頑張ってください。
