The shelf life of chilled foods is very short, so we need to use the refrigerated display cabinet to keep the food fresh. Any machine needs maintenance after a period of use. Let's take a look at the maintenance methods of the refrigerated display cabinet. ? First, we must first choose the protective agent. At present, there is a method of spraying wax, and some methods are cleaning and maintenance agents. These two are essential for the maintenance of the refrigerated display case. Spraying wax is mainly for various wood and gel materials. Our refrigerated display case features two different fresh fragrances of jasmine and lemon. The latter is mainly suitable for all kinds of wooden and glass solid wood refrigerated display cabinets, and the mixed materials are more widely used. These two materials can keep the appearance of the refrigerated display cabinet glazed. Second, the refrigerated display cabinet must remove the watermark on the paint surface, how can we quickly remove the watermark? You can put a clean wet rag on the watermark on the desktop and then iron it on the iron at 30 degrees, so that the moisture that has penetrated into the cabinet will evaporate and the watermark will disappear. However, the rag used in this method cannot be larger than the temperature of the thin iron, and the temperature is not adjusted too high. Otherwise, even if the watermark on the desktop disappears, there is a branding that can't be removed. Third, to eliminate the precautions of the paint surface of the refrigerated display cabinet If you accidentally leave the surface of the wooden refrigerated display cabinet with hot marks, the refrigerated and frozen display cabinet can be removed as long as it is wiped with a rag in time. However, if the hot marks are too deep, you can use iodine to gently smear on the refrigerated display cabinet or apply Vaseline oil on the refrigerated display cabinet and wipe it with a soft cloth every other day to eliminate the hot marks.
