It is normal that the shell of air conditioner will turn yellow due to long-term use. The top of the air conditioner shell is easy to accumulate dust, so the place with the most dust is the top of the air conditioner, but we should not only clean the top of the air conditioner, but also pay attention to the dead angle of the air conditioner, which is the most easily overlooked place when cleaning. All we have to do is wipe the dust off the air conditioner shell with a wet rag.

Secondly, clean the filter inside the air conditioner.

1. Unplug the air conditioner before cleaning it to prevent electric shock during cleaning.

2. Open the cover on the air conditioner and take out the dust-filled air conditioner filter.

3. Then pour some detergent into the air conditioner filter, brush it with scouring pad and clean it. Put the cleaned air conditioner filter aside to dry, and don't expose it to the sun.

4. Prepare another bottle of toilet water, spray it on the rag, then wipe the fan on the air conditioner condenser tube with the rag, and wipe it up and down. Don't wipe it from left to right, it will easily damage the fan. At the same time, wipe the inside and outside of the air conditioner with a rag to remove dust and stains.

5. Finally, put the dried air-conditioning filter back to its original position, cover the air-conditioning cover and plug in the power supply. The air conditioner thus cleaned is cold and windy to use.
