For dust that cannot be vacuumed, use a duster to slap out of the car. For example, a velvet chair can dust the hole from the mat and then use a vacuum cleaner. It should be noted that dusting should not be too strong, otherwise the dusted object will easily break down. In addition, when dusting, because there is a lot of dust flying in the car, so the door must be completely open, and the air conditioning should also be maximum, in order to blow the dust out of the car.
Before using the vacuum cleaner, you can put a layer of stockings on the junction between the suction nozzle and the hose at the front end, which is a fairly good filter that can improve the dust cleaning efficiency. maybe you think your seat should be clean, but you can see when you look at the stockings, there's a lot of cotton on it.
The benefits of a simple filter made of stockings go beyond that. Because of the structure of the vacuum cleaner itself, the air can be sucked out from the inside. With a stocking filter and the filter of the vacuum cleaner itself, a two-stage filter can be formed to prevent the vacuum cleaner from discharging dust in the vehicle at the outlet again. If you feel uninsured, you can also put a wet tissue on the outlet, so that the filter will be better, but also to prevent the odour of the emission.
