As a commonly used product, the handle is very easy to stain, especially stainless steel handles, so it is necessary to understand the maintenance and cleaning methods, according to industry experience, to introduce you to the tips of the handle maintenance.
Sometimes the key is not easy to open, which is caused by dust in the keyhole. A vacuum cleaner can be used to align the keyhole, suck out dust and add a few drops of lubricant. If the handle is made of metal, you can wipe it with toothpaste to make it brighter. If the handle is rusted, you can wipe it with a soft cloth dipped in tomato juice, which can effectively remove rust without scratches.
