大家推荐三个小技巧，希翼能帮到广大商户。
We recommend three tips, hoping to help the majority of businesses.
一、流行的中纤板烤漆展示架，更怕的是水，所以如果油漆表面变脏了，一定不要用湿毛巾，可以用酒精祛除污渍。因为水容易让板发涨而且油漆进水后易脱落，另外在窗口位置如果有强烈的太阳光不能常时间爆晒，否则白色也容易变黄。
1、 Popular MDF paint display rack, the most fear is water, so if the paint surface becomes dirty, do not use a wet towel, you can use alcohol to remove stains. Because the water is easy to make the board rise, and the paint is easy to fall off after entering the water. In addition, if there is strong sunlight in the window position, it can not be exposed to the sun for a long time, otherwise the white is easy to turn yellow.
若是在北方基本上每个店面都会有暖气，尽量这个位置不要放展示架，长时间的热量会让油漆层掉落。总之烤漆展示架要注意防水防潮。（小提示：金属展示架不再怕水，因为大家都有防氧化处理，不怕生锈。）
If in the north, basically every store will have heating, try not to put the display rack in this position, the heat for a long time will make the paint layer fall off. In a word, we should pay attention to the waterproof and moisture-proof of the display frame. (tip: metal display shelves are no longer afraid of water, because we all have anti-oxidation treatment, not afraid of rust.)
二、选用专用家具清洁祛污剂，如果污渍很难去除，不能太用力以免划伤油漆，比较凑效的办法是用牙膏。挤少量白色牙膏在软布上，轻轻擦拭污迹，切记不可使用蛮力硬擦。
2、 Choose special furniture cleaning agent, if the stain is difficult to remove, not too hard to avoid scratching the paint, the more effective way is to use toothpaste. Squeeze a small amount of white toothpaste on the soft cloth, gently wipe the stain, remember not to use brute force hard wipe.
三、保养的还是日常保养，定期保养才是必要的，随时准备专用家具清洁剂，牙膏使用的次数更多一两次，不能多用，另外还可以用香蕉涂抹污渍，再用软布清洁。
3、 The focus of maintenance is daily maintenance. Regular maintenance is necessary. Always prepare special furniture cleaner. Toothpaste can be used one or two times at most. You can't use it more. In addition, you can use banana to smear stains and then use soft cloth to clean.
