The 6 most common adhesives and how to remove them
How to remove tape? This question is closely related to the question of the adhesive of the respective tape. Some adhesives can be easily removed, others are intended for permanent bonding and cannot be removed at all or can only be removed with residue.

Has the adhesive set properly? Then you should try the following solvents one after the other:
- Mineral spirits
- a mixture of 50% ethyl acetate and 50% xylene
- a mixture of 40% mineral spirits, 40% white spirit and 20% acetone
These mixtures can only swell the acrylic adhesive, but not completely dissolve it.
2. Remove the rubber with a spatula and petrol
In order to remove a rubber adhesive tape without leaving any residue, the condition of the adhesive and backing should first be checked.
Is the adhesive still soft and can the adhesive tape be peeled off easily? In this case, you can remove residue with mineral spirits.
Has the adhesive hardened slightly, is the carrier brittle and cracked? Then you should heat the tape with a hair dryer and then carefully peel it off.

Hot melt adhesives, also known as hot melt adhesives or synthetic rubber, consist of synthetic resins that melt at hot temperatures.
Residues of hot melt adhesive can be removed with the following means:
