What substrate and cleaning agent should be used when dealing with traupalin patches?

Using acetone as the cleaning agent for traupalin patches is appropriate due to its effectiveness in breaking down adhesives and residues associated with these patches. Acetone is a strong solvent that can easily dissolve various substances, making it suitable for cleaning surfaces that have been in contact with sticky materials.

When dealing with traupalin patches, it's crucial to ensure that the substrate can withstand strong solvents without being damaged or degraded. Acetone is particularly useful in instances where a thorough and efficient cleaning process is necessary to prepare the surface for further treatment or application.

Other options like water and soap might not be effective enough in removing adhesive materials; they typically work better for general dirt and grime rather than residues from strong adhesives. Similarly, alcohol, although a common solvent, may not be as effective as acetone for certain adhesive types found in traupalin patches. Sandpaper could potentially damage the substrate by abrading the surface and is not suitable for cleaning when a delicate touch is required.
