It all depends on what the glue is! Sometimes, especially on a flat surface, it can work to re-apply and rapidly lift off a part of the label that still has stickiness, doing repeatedly as required. Otherwise with solvents Iād try first IPA, which generally offers least risk of damaging anything, then in approx increasing order of damage risk, white spirit, acetone, toluene
Yes, that fits mg indication of IPA being least damaging. However IPA does nog remove all adhesives encountered with labels, hence my inclusion of more aggressive ones to try if IPA doesnāt work.
Best with more aggressive solvents is minimum contact time. If they dissolve the insulation of make it sticky then as someone suggested just cut off the end.
Something simple like a āsticker removerā typically works fine. White Spirit or Benzine (not sure what is the correct UK translation) works good for glue-type residues too.
