There are labels, trademark stickers, instruction stickers, etc. on the cups and bottles. Sometimes, for the sake of beauty, after the stickers are torn off, offset printing is often left. The treatment method is as follows:

Steps:

1. Pour a few drops of essential balm on offset printing and rub it with a hand-drawn circle. The essential balm has a strong smell, so you can wear rubber gloves to operate it.

2. Offset printing is mixed with essential oil of wind oil with friction, so you can wipe it off with toilet paper or rag. Generally, the glass is fixed last time. If it is a plastic product, it may be necessary to repeat the operation once or twice and it will be clean.
