You are right there Ken, nothing like a bit of alcohol to remove gum residue.
If it is really stubborn then try a drop of alcohol on a bit of Duraglit !

Trip to the local motor factors - a squirt of either Carburettor cleaner, or Brake cleaner - normally shifts most things

I use a scraper from Machine Mart that holds the single sided razor blades. With label remover (usually from CPC) and a little time this removes everythinmg the blade comes into contact with. Ideal for the hard stuff that will not come off any other way.

Think it was designed to scrape off gasket residue but it does work on most smooth surfaces without gouging.


FWIW

I also use the technique from Phil of using a razor blade at the corect angle to scrape without cutting into the plastic, followed by a cleanup with label remover and a polish with Brasso. Alternatively I have used fine wet and dry followed with a polish using Tcut on smooth surfaces.

Plus-Gas might work as well. If the tape still had some of its sticky properties, one way I have used is, after removing the top plastic layer, to then apply the same type of tape to the adhesive layer and dap it to amalgamate the two tapes. This will pull off the adhesive from the surface.

My experience is that Windolene is a very good water-based solvent for all sorts of glue and adhesive deposits. It will remove Evo-Stik, the insoluble adhesives used for some bottle labels and will soften paraffin wax. Wonderful stuff!

I too have found that citrus-based solvents are excellent for removing a wide range of adhesive and other deposits without harming the base material. Sometimes you have to leave them for several hours or even days, but it doesn't seem to evaporate much and if soaked into cottonwool it can be left sitting on the surface for ages.

As in all things vintage, patience is everything and I wouldn't use a sharp blade or any other kind of scraper until or unless all other options were exhausted. You may be able to polish out damage, but the different patina will always show.

Cheers

Billy

I'm now fairly certain that the plasticisers have migrated into some of the dried on deposits, making solvent removal impossible. Lots of elbow grease and T-Cut has made a big improvement though, and the damage is no longer obvious.

Thanks for all suggestions. This thread will be useful for future reference.

Limonene or Limonene+alcohol is one I have successfully, another is menthol+alcohol.

funny you should should mention plasticisers, PIB (polyisobutylene/ polybutene) a plasticiser in Blue Tack, is also a great cleaning tool, it`s not the PIB in it, its the very fine powdery grit or whatever it is they put in it that does the job.
it acts as a very gentle abrasive (not unlike T cut).
I`v used blue tack for all sorts of removals, it may help for some finer work or on clear plastics.
