Goof Off or Goo Gone.
Most glues can be softened up with Goof Off, then peeled off.
Rub it with a rough rag and Goof Off, it will soften enough to be peeled off.
Goof Off will remove almost any glue, including super glue types from laminate and hardwood flooring. Just rub with a rag and a few drops of Goof Off and the glue soon softens and can be peeled off. This has not harmed 3 different types of flooring that I've tested it on.
There is casein in some glue, particularly label glues.
I used sodium sulfite 3% by wt.,the label was removed but I didn 't know why ? The composition of the gle was ammonium hydroxide.
Try spraying WD-40 on it and let it saturate the glue for about a minute and it will peel right off. It will need to be cleaned with soap because it will leave a residue behind.
Use a dab of cooking oil and rub the glue off then clean the mirror with window cleaner to remove oil. No harm to the mirror, works on any type of glass.
Warm water and a little scrubbing can remove white glue or school glue.
Isopropyl will remove only elmers glue from plastic, not super glue. once it gets on there, you can't remove it.
From an operational point of view, a sticker labeling machine offers the following advantages over the wet glue labeling machine:You do not need to change any parts in the case of bottle or label changes.There is no cleaning required, so the machine remains clean throughout the operation, unlike wet glue labeling machines.In a wet glue labeling machine, if label or bottle size is changed, then you need to replace the machine part acceptable to bottle and label size and change part time is around 30 minute so again reduction in the production time.Only disadvantage with Sticker labeling machine is the price of sticker label , which is high compared to wet glue labeling machine.
I usually soak tins or glass jars in hot water and then use a scrubber after they've been soaking for a while. Sometimes, depending on the label it needs to soak for quite a while (say, an hour). I've also heard that peanut butter can help get those off, by rubbing the peanut butter in and then scrubbing it all off. Sometimes oils like that can get in under the glue and separate the glue from the surface.
A type of casein glue usually holds labels on.
