1. Flat screen TV: Do not disassemble it without permission.
It is a principle not to disassemble the flat-screen TV without permission. In addition, the LCD screen and plasma screen are very fragile, so it is necessary to avoid strong impact and vibration when cleaning, and do not put pressure on the screen surface. When cleaning LCD TV, you can gently wipe off the stains with a soft cloth dipped in a little water, but don't sprinkle water directly on the display surface. It is best to wipe it with a special cleaner.
2. Air conditioning: No water can enter important parts.
The air conditioner should be cleaned regularly. The traditional air-conditioning cleaning method can only simply clean the filter screen and wipe the evaporator surface, but it can't completely clean the gap and air supply system of the air-conditioning evaporator, and the inside of the evaporator is the place where dust is the most serious and bacteria and viruses are the easiest to breed. When cleaning the air conditioner, wipe off the dirt on the air conditioner shell with a soft dry cloth, and be careful not to scrub it with hot water or flammable oil. Take out the filter screen of the air conditioner, rinse it with clear water or clean it with a vacuum cleaner, dry it and put it back into the air conditioner. In addition, it should be noted that when cleaning the outdoor unit, the surface of the condenser of the outdoor unit can be washed with clean water, and the hood can be covered after drying, and no water can enter other parts.
3. Refrigerator: Glycerol can be used to protect the inner wall.
The condenser and compressor of the flat-back refrigerator are built-in and do not need to be cleaned frequently. Dust on the surface of condenser and compressor can be blown off by pumps and other tools. Do not scrub with water or a wet rag. Generally speaking, we should clean the refrigerator more than twice a year. When cleaning the refrigerator, first cut off the power supply, gently scrub with a soft cloth dipped in water or detergent, and then wipe the detergent clean with water. The interior of the refrigerator can be wiped with boric acid or disinfectant paper towels, and it is easy to defrost the refrigerator with boric acid. The inner wall of the refrigerator can also be wiped with glycerin to form a thin protective film, so that milk or food residue can be easily wiped off when it touches the inner wall.
