What is limescale in the bathroom?

I clean the bath every day, but there are stains that can’t be removed with bath detergent.

Dirt that doesn’t come off with bath detergent? Now, let me explain what the dirt in the bath is all about!

The identity of the dirt ① Limescale

Limescale caused by minerals and chlorine in tap water

Tap water is natural water that is stored and treated at a water treatment plant before being sent to each household. In other words, it is originally mineral water containing Ca (calcium) Mg (magnesium) Na (sodium) K (potassium)! The main component of the white substance that remains after tap water dries is calcium carbonate, which is a combination of these mineral components and the chlorine injected at the water purification plant.

The identity of dirt ② Soap scum

Metallic soap made from a mixture of soap and sweat

The dirt around the bathtub, bath tub, and solid soap holder is called metallic soap (= soap scum). Fatty acid sodium, which is the main component of soap, is combined with Ca (calcium) and Mg (magnesium), which are the main components of human sweat, and calcium carbonate in water. In addition to being left undissolved in water, metal soap can also feed mold, so you want to deal with it as soon as possible!

Citric acid to remove limescale in the bathroom

Citric acid is used for cleaning toilets! Why do you use citric acid for small items in the bathroom and limescale stains in the bathtub?

Next, let me explain how limescale can be removed with citric acid!

Properties of limescale and soap scum

Calcium carbonate, the main component of limescale, and fatty acid calcium, the main component of soap scum, are both highly alkaline. If you leave it on the bath tub or bath tub, it will harden and won’t come off even if you rub it. Scrubbing too hard can scratch the surface and cause more dirt to accumulate.

How citric acid removes limescale

Citric acid, as the name suggests, is an acidic substance and is the sour ingredient found in lemons and vinegar. It is sold at drugstores and supermarkets as a crystalline powder or as an aqueous solution. By neutralizing limescale stains with alkaline properties using citric acid, the limescale will fall off.

Precautions when using citric acid

Caution!? Citric acid is safe and can be used anywhere.

Don’t worry, citric acid is highly safe and is used in beverages. However, since it is an acidic type substance, there are some points to be careful about.

①Dangerous if mixed

If you use citric acid and chlorine-based products together, toxic chlorine gas is generated and is dangerous. Also use a clean spray bottle for the citric acid solution.

②Materials that cannot use citric acid

Calcium carbonate is the raw material, and marble dissolves in citric acid. Also, metals may rust or corrode due to acidic substances, so caution is required. Stainless steel is strong against acid, but it is safe to use it for a short time.

③ Do not leave with citric acid on

Citric acid is a cleaning agent with high sterilization and deodorizing effects, but if citric acid is left for a long time, mold will occur. Surprisingly, there are many molds (fungi) that prefer weak acidity in toilets and baths. When soaking in a bathtub, bathtub, or bath boiler, keep it for about 2 hours.
