Glue removal?

[Malcolm T]

What on earth removes caked on 40 year old Evo Stik residue .

Petrol.

Chlorinated solvent - ethyl chloride? Trichloroethane? Chloroform? Trichloroethylene?

40-year old glue was based on solvents in common use 40 years ago. And they were effective and economical - but hazardous. Modern replacements are more expensive, less effective - but don't have the environmental overhead.

Isopropyl alcohol or label remover (I think it’s citrus based but works very well on stubborn residues)

What is the glue gluing??

Solvents range from the weak to the murderous, in times past I have successfully dissolved adhesives and the nasty goo slathered on to tuned circuits in Japanese 1970s transceivers but have also melted the dielectrics in Polyvaricon type tuning capacitors and trimmers as a side effect..

It was just a curiosity question as on some old equipment i had there was foam strip inside for stabilizing batteries or battery packs , i have never found a definitive solvent for it , defiantly wouldn't use trice today D;
Yup the chemicals available today are not as they were !
Thanks ,

There is a hardware shop 'label remover' which smells like some kind of white spirit blend, but is much more effective than that alone. It takes the residue off jars in a trice, and I've had success with other glue types as well.

If it is Evostik Impact adhesive, there is a solvent available from the manufacturer:

There is a Safety Data Sheet (SDS) that gives details of the chemicals in it.

Some PCB's used glue to hold the odd component in place while soldering. Over time this turns from white to brown, absorbs water and becomes conductive (Samsung TVs).

Removing this can be tricky - I use freezer spray which makes it easier to remove with a blade. This also works on hot-melt adhesive.

I still have a tin of Evostik cleaner that I bought in the late 1980's. Unfortunately the white-on-red printing (top right-hand corner) which contains the description of its contents is now almost illegible due to diffusion of the red into the white. From what I can make out it says

"CONTENTS HEPTANE AND [ ? ] SOLVENT NAPTHA (PETROLEUM) ESTERIFIED [ ? ] [ ? ] BENZENE"

The front of the tin says that it is a "NEW IMPROVED FORMULA" .

The contents smell like the smell of current- production Evostik.

I confess to not having tried it on Evostik, but I keep a can of automotive brake cleaner (which I think is largely hexane) in the workshop, and find it effective for dissolving all sorts of adhesives, as well as solder flux (I use it instead of the incredibly expensive solvent sold for the purpose in the electronics industry). It's easy enough to get hold of and try.

If tempted to use petrol as a solvent, it should be noted that any spillages will strip certain paints off, notably paint from 1940's/1950's era. It appears to be down to the ethanol content.

No votes for acetone?

edit - be warned that acetone can melt many plastics, especially ABS.

[Phil__G]

40-year-old Evostik is Toluene based, so the best solvent to soften it is Toluene.

[brenellic2000]

My favourite choice/elixir is plain cigarette lighter fuel as it quickly evaporates. 'Petrol' contains too many unwanted additives and leaves sticky residues.

Vote here for acetone, my go to chemical for cleaning/gunge removal. Or try xylene another good one. Both easily obtainable via ebay.
