Do you know how to maintain your suitcase?   You may pack your bags in a hurry to get on the road when you go out in order to catch the bus. You may run quickly with your suitcase in order to catch the bus, but have you ever noticed that your suitcase can withstand such a toss?   Today, let's check how to use your suitcase correctly.   Whether the suitcase you are using is made of aluminum alloy, PVC or canvas, please remember that it is necessary to regularly wipe the appearance with a towel. Regularly cleaning the appearance of the suitcase can not only prevent the aging and corrosion of the suitcase materials, but also make your suitcase look like new and make your travel mood more comfortable!   So, how should we clean the outside of the box?   Different cleaning methods should be adopted for different materials. For cases made of aluminum alloy and PVC materials, wipe the whole appearance with a wet towel first (the appearance can be cleaned repeatedly with detergent, and remember not to clean with a hard brush). After the appearance is cleaned, wipe the appearance with a dry towel to ensure that there is no water left and prevent air corrosion. If it is a canvas box, you should first use a broom to clean the dust on the surface, and then use a soft brush to clean the surface of the box with water until the stains on the surface are cleaned, and then use a dry towel to wipe the surface of the box. Finally, you should open the box and put it in a sunny place for drying, which is conducive to the evaporation of water as soon as possible.   Interior cleaning of suitcase   The cleaning of the interior of luggage is relatively simple, which can be wiped with a vacuum cleaner or a wet cloth. It is better not to use any detergent to wipe the metal parts inside and outside the box, and dry the metal parts with a dry cloth after cleaning to prevent damage to its outer coating or oxidation and rust. Check the roller, handle, pull rod and lock at the bottom of the box, remove the stuck debris and dust, and send the damaged parts for repair in time. Generally, all major luggage brands provide repair and replacement services for accessories, and do not try to repair by yourself.   When you go out and use your suitcase at ordinary times, if the road surface is relatively flat, you can use two or four wheels to pull forward. If the road surface is relatively rough, you'd better use two wheels to pull forward. If it's a very uneven road surface, you'd better hold the suitcase with both hands to move forward, so as to protect your suitcase to the greatest extent. The wheel is the key component of the suitcase. If the wheel is broken, the suitcase is half broken!   You should also pay attention to the zipper maintenance of the suitcase at ordinary times. Before opening the suitcase, it's best to put the suitcase flat on the ground, and then open the zipper of the suitcase appropriately. If the zipper is not very smooth, don't pull it hard with brute force. It's best to apply some lubricating oil before opening it, so that the zipper of the suitcase is not easy to be damaged.
