Cleaning jars to reuse

[Gotthetshirt23]

Jam and chutney time of year - has anyone got a genuine way to remove the sticky residue from the outside of jars ?
Some labels soak off in seconds - others seem welded on and leave a sticky gunky unmovable film that I can't seem to get off ?
I don't have a dishwasher...
Help ?

Brillo pads (wear rubber gloves).

Lighter fluid on a bit of kitchen towel. Gets rid of all sticky stuff very easily. Does smell though, and they will need a really good wash afterwards.

Very hot soapy water, then a bit of wd40 on cloth.

IPA

Mayonnaise

IPA ? As in beer ?
Mayonnaise is no good sorry as already tried that

isopropyl alcohol

Nail varnish remover

Lakeland sell a bottle of stuff called Sticky Stuff Remover. It is probably just an expensive version of one of the previously mentioned chemicals but it does work.

WD40 removes adhesive residue. Even says it on the can.

Don't put them in the dishwasher [learned from experience].

Boiling water and scrubbing. If that doesn't work they get recycled!

I love jars with plastic shrink wrapped labels!

Soak as much off as possible.
Then smear a good dollop of olive oil over the sticky gunk, leave for a while, then clean off with neat washing up liquid and a damp metal pan scourer

I gave up trying to clean any jars that come from
Lidl as the labels never seem to come off whatever I try 😬

I have a bottle of sticky stuff remover that it probably 20 years old, so I use that. It seems basically a thin oil, so that might work? I would smear the label with oil and then set to work with the edge of a sharp knife (disclaimer: my hands and arms are covered in scars from doing things like this, so take more care than I do!)

just put a bigger label over the sticky bit

Scrape off with a knife (try and serrated and none). I promise it is the answer you are looking for!

When you finally get the jar clean, buy a white pen which can write on glass to label it and then you won't have the same problem next time round. I got mine from an art supply shop.

Acetone

but does the white pen stuff come off? or are you doomed to always use that jar for the same contents?
