We can use ordinary cleaner to help remove the self-adhesive label from the plastic bucket. You can choose a cleaner with good decontamination effect, such as detergent or alcohol. Pour a proper amount of detergent on the wet cloth, and then gently wipe the surface of the label. Remember to use a wet cloth, and don't pour the detergent directly into the plastic bucket, so as to avoid the liquid from infiltrating into the bucket.
If the label is stubborn, try to soften the label with hot water. Pour hot water into the container, and then soak the plastic bucket in the hot water. After a few minutes, wipe the label surface with a damp cloth or sponge. Hot water can soften the glue and make the label easier to tear off.
If all the above methods have no effect, you can also try to remove the label with oily substances. Such as edible oil or vegetable oil. Pour the oil on the surface of the label, let it stand for a while and then wipe it with a wet cloth, which often has unexpected effects. This is because oil can dissolve the glue, making it easier to tear off the label.
If all the above methods fail, you can also consider using a special glue remover. There are some special glue removal products on the market. You can choose to buy it according to the actual situation and use it according to the instructions.
To sum up, we can try to use detergent, hot water, oily substances or special adhesive remover to clean the waterproof self-adhesive labels on plastic barrels. Each method has its own applicable scenarios and precautions. Please choose the appropriate method according to the actual situation. I hope my suggestion will help you! Remember to use detergent carefully and keep the ventilation environment!
