A certificate is a label! Use label cleaner (solvent) to remove labels from various materials without damaging the surface (use less plastic). Dissolved substances in the product will penetrate the label and decompose the adhesive. Then wipe off the remaining adhesive easily with a rag or paper.

In short, get rid of all kinds of annoying labels. Any household kitchen supplies and gifts, handicraft shops and offices are of great use. If the detergent smells, you can wash it several times. Don't let children touch it. In addition, it is necessary to prevent fire. The real method of using soil is to directly cover the soaking with a wet rag, and the label can be removed in a few hours.
