2. Use salt, cooking oil and cotton swabs. First, we apply cooking oil to the label, let it soak, and then rub it with our fingers. At this time, the paper part of the label will be erased, but the glue at the bottom needs to be salted. After the paper is treated, the edible salt is sprinkled on the offset printing place, and the residual offset printing can be taken away through the friction of the edible salt and the adsorption of cotton swabs, and finally the stainless steel can be cleaned normally.
Step 3 use alcohol. We can apply alcohol to the stainless steel where it is labeled. The higher the alcohol concentration, the faster and more thorough the label removal and offset printing. After alcohol saturates the label, we can tear off the label by hand and wipe off the offset printing at the bottom with a towel.
