Method 1: You can pat window cleaner with your hand, put it into a basin with cleaning liquid, and wet window cleaner's cleaning towel. Tie window cleaner's safety rope to your hand, put half of it in the window and the other half outside the window, and the two should correspond to each other to form suction.

After sucking, you can start cleaning the window, so that the scope and angle of internal and external cleaning are the same, and the purpose of synchronous internal and external cleaning is achieved.

Method 2: When cleaning the glass, break the glass window cleaner by hand. When starting to use, remember to put the safety rope around your wrist to prevent it from falling. Wet the product and apply the cleaning liquid to the cleaned surface. Put a piece with a rope outside the window, remember that the rope should be long enough to clean every corner of the product, and put a sucker with a handle inside the window.

Method of selecting glassware

1, choose the cleaning cloth on the window cleaner. The cleaning cloth must be soft enough. The cleaning cloth is not only too hard to stick on the window glass, but also easy to scratch the glass.

2, it is to choose products with high suction. If it is the top of the family, you should pay attention to this for safety. In principle, the suction force is safe when it is more than 3 times the weight of the fuselage, and the greater the proportion, the higher the safety. However, the greater the suction, the greater the noise. According to the friction coefficient between the glass and the cleaning cloth, we can choose products that can automatically adjust the suction force.

3. Check the product year, especially the brands appearing on 20 18 are mostly cottage brands, and the quality of core technology products is difficult to ensure the choice of product shape. Try to choose a round shape for home use, and the cleaning effect is better, if it is commercial.
