"Bathroom (bath) detergent" is indispensable for washing bathtubs, bath tubs, and bath chairs. However, there are so many types that it is often difficult to know which one to choose.
In this article, we will introduce the points you want to check when choosing a bathroom detergent, and the recommended products based on that.
[Correction: 17:00 on January 18] There were some errors in the explanation of alkaline detergents and acidic detergents. I apologize and correct it
There are a variety of bathroom detergentsIt is effective to use each liquid according to the type of dirt.
The liquidity of the detergent is always clearly stated on the packageNeutral detergent has a pH : hydrogen ion concentration) is set to 7.
Since it is neither alkaline nor acidic, it can be used to clean not only the bathtub, but also the floor, walls, basin, chair, mirror, and everything else in the bathroom. In particular, it is attractive that natural stone materials such as marble can be washed (*), and if you do not have rough skin, it will not cause rough skin when liquid is splashed on it.
However, the cleaning power is "moderate", so it can be difficult to remove stubborn stains. It is ideal for light daily cleaning.
(*) We recommend using a neutral detergent that clearly states that it is compatible with natural stone materials. Even in that case, use a soft sponge when washing, rinse with water immediately after washing, and wipe off the moisture.
Alkaline detergents have a pH of over 7. Of these, detergents with a pH up to 10 are classified as "mildly alkaline".
Alkaline detergents are good at removing acidic (low pH) stains. Specifically, it is effective when used to remove sebum stains and black mold.
However, it is not good at removing alkaline dirt like liquid. Also, don't forget to wear rubber gloves when using strong alkaline detergents with a pH of 11 or higher, as they have a large effect on the skin.
Comprehensively considering the dirt that occurs in the bathroom, a weakly alkaline detergent is the most well-balanced and removes the dirt. The most common type of bath detergent is weakly alkaline.
Acid detergent has a pH of less than 7. Those with a pH of 3 or higher are classified as "weakly acidic".
Acidic detergents are good at removing alkaline (high pH) stains. Specifically, it is effective when used to remove water scale and soap scum.
However, it is not good at removing acidic stains, which is the same as liquid. Also, don't forget to wear rubber gloves when using strong acidic detergents with a pH of 3 or less, as they have a large effect on the skin.
In addition, there are the following points to note.
Acid detergents have the label "Do not mix". Do not mix with chlorine-based detergents or bleaches to produce toxic gas, so please do not use them at the same time. When it comes to detergents, the mainstream was the "direct liquid type," in which the liquid is directly applied to the item you want to wash, but now each manufacturer's main product is the "spray type." Recent bathroom detergents have improved cleaning ability, and you can remove a lot of dirt just by spraying it, letting it sit for a while, and rinsing it off with water (stubborn dirt needs to be rubbed with a sponge, etc.).However, even if it is a spray type, there are various characteristics in the shape of the nozzle and the method of spraying for each company and product. If you can spread the liquid over a wider area, it's easier to reduce the number of times you spray it. I would like to look carefully at the nozzle when choosing.
Even though we call it a “spray,” the shape of the nozzle and the method of spraying differ depending on the manufacturer and the product (Source: Kao)There is also a chlorine-based "mildew remover" that is useful for cleaning the bathroom.
The fungicide is alkaline, and as the name suggests, it contains chlorine-based ingredients that are highly effective in removing mold and can also remove mold. As mentioned above, even a (weakly) alkaline bathroom cleaner can remove black mold to some extent, but a mildew remover is better for more thorough removal.
However, chlorine-based fungicides generate toxic gas when mixed with (weakly) acidic detergents, alcohol, or ammonia. As with acid detergents, chlorine-based fungicides also have the label "do not mix", so be careful when handling them. If you absolutely want to use an acid detergent together, be sure to thoroughly wash away the fungicide with water before using the acid detergent (same for the reverse order).
When removing mold in the bathroom, it is more effective to use a mildew remover. However, if it is mixed with (weakly) acidic detergents, alcohol, or ammonia, it will generate toxic gas, so please be careful when handling it. >Check "Kabi Killer" spray type (400mL) on Amazon!Based on the above, we will introduce four recommended bathroom detergents.
