The astronauts do some cleaning between their duties.

As people live there, it becomes messy after meals and there's also garbage to be disposed of.

Between their duties, the astronauts clean the meal area, change the air purification system's filters, collect the garbage, and clean the walls and floors. They use liquid detergent, disposable plastic gloves, multi-purpose wiping cloths and a vacuum cleaner for cleaning.

To clean, they spray the detergent, wipe with the cloth, and vacuum the dust. When using the detergent, they wear disposable gloves. Collected garbage and used gloves are brought back to Earth.
