Placing too many trash cans will take up space and increase the proportion of pollution. Generally, one in the kitchen and one in the living room will suffice. If the flushing function of the toilet is good, the toilet paper after defecation can be flushed directly with toilet water, and there is no need to put a trash can. If you find it really inconvenient, you can place a small trash can with a lid. Trash cans should also be placed in a well-ventilated area to dissipate the smell of garbage in a timely manner.

Since the garbage bags will be damaged and thus contaminate the trash can, it is recommended to clean them once a day. When cleaning, use a brush to clean the gaps. It is best to disinfect with 84 disinfectant, and finally rinse and dry.
