Why is toilet cleaner acidic and kitchen cleaner alkaline?

Human urine is alkaline because the human protein end product is urea, which of course is alkaline. It is birds that produce uric acid, and human urine does not contain uric acid, which is easy to confuse.

Human urine contains urea, inorganic salts, some end products of organic metabolism, and very small amounts of sugar, among others. Urine stains are mainly caused by urea, so the toilet cleaner should be acidic to neutralize the alkaline urine stains.

The dirt carried by the tableware is mainly the residue of food, and whether the main dirt is easy to remove has a lot to do with the type of food during the meal. Most of the tableware is stained with more animal fat, which is more difficult to clean. Oils and fats are hydrolyzed under alkaline conditions (such as NaOH) to produce sodium higher fatty acids, which contain lipophilic and hydrophilic groups, which are used to remove oil.

So dishwashing detergent is alkaline.

Yijieli furniture kitchen cleaning paste is weakly alkaline, does not hurt hands, and does not irritate. Because it is a biotech cleaning paste, the cleaning function is very good. Very heavy dirt can be removed, the bottom of the stainless steel black pot can be polished, the stainless steel faucet can be polished, and the porcelain pot and porcelain dirt can be removed.

Toilet dirt is mainly alkaline, for example, there is a small amount of ammonia in the urine, and ammonia is alkaline, so it is dissolved with acid.

Kitchen dirt is mainly oils and fats, which will be learned in organic chemistry in the future. Alkaline substances can decompose oils and fats.

So dissolve with alkali.

Toilet cleaning acidity is mainly to remove limescale stains from the toilet.

1st floor my son ignored him.

It's a relatively small white, big brother, the kitchen oil stain is not acidic, it will not change the PH test paper, and the kitchen cleaner is not alkaline, but surfactant and emulsifier, which dissolves the oil stain.
