Why do hotels use washing powder and 84 sheets?

Chlorine bleaching refers to bleaching with sodium hypochlorite or chlorine water. There is also 84 disinfectant, the ingredient is sodium hypochlorite! This is just a diluted sodium hypochlorite solution.

Flax bleaching does not mean that you can't bleach with chlorine, but how many times you can wash it. When the hotel signs a contract with you, there must be a clause: how many times should the linen be washed (for example, 150-200 times), otherwise the hole or tear will be compensated according to the price. What kind of sheets do you think can make you bleach with sodium hypochlorite for 200 times? Can you still take it out?

Normal linen washing can only use hydrogen peroxide, not chlorine bleach, whether it is sodium hypochlorite or chlorine water, it can only be used in special occasions. For example, some colored stains can't be washed off by water, or they can be used as an aid when the whiteness is not enough after a period of time.
