2. Wash the sofa with detergent once a year, but be sure to wash the detergent thoroughly afterwards, otherwise it will get dirty more easily. Regarding the choice of cleaning agent, you can choose a special cleaning agent containing antifouling agent. Some silica gel sprays have dust-proof effect, and they can be sprayed once a month.
3. Fabric sofa with sheath can be cleaned generally. Among them, the elastic sleeve may be cleaned in the washing machine at home, and the larger cotton and linen sheath can be taken to the laundry for help. It should be noted that some elastic sheaths are easy to dry and do not need ironing. Even if ironing is needed, the appearance of the cloth should be considered, so it is more suitable to iron the inside of the sheath. If the sheath is cotton, it is not suitable for ironing.
