It’s getting the metal strips off in the first place that Has put me off. Getting a sharp and flexible scraper behind it? Multitool is probably overkill. I have all the solvents for dealing with the residue. Those Big Wipes seem to do a good job on most things.
Be careful with the big wipes, they are not great when decorating. If you wipe down woodwork with them it's very hard to stick masking tape to it afterwards due to the moisturiser.
All the chemicals.
White spirit, or isopropyl alcohol, seem to work on most things still sticky (and they aren't too utterly awful to work with).
Acetone works on other stuff.
TBH, even soap & warm water is good for a lot of self adhesive residues.
