How can I remove the sticker on the suitcase?

The stickers on the suitcase can be cleaned using the following methods:
Heat the sticker with a hair dryer, and when the sticker gets hot, it can be easily removed. Rub it again with an eraser for better results.
Sprinkle a few drops of essential balm on a hot towel. Then cover the sticker, cover it for a while, and slowly rub it off with a towel before it falls off.
If it is plastic or metal surface, you can use a cotton swab to apply a little cooking oil, and it will all come down after 1 hour; If the suitcase is made of cloth, spray it with steam from an iron for a while and then tear it off easily.
