Found great lifetime way works 99% to 100% of times that is almost free.

|1| Soak jar in water (usually a day works ok, rarely longer, often shorter)
|2| Scrape label off with butter knife or fork or fingernails or what not
|3| Collect in a basket or drawer or shelf until you have enough for next
|4| When ready, take basket outside and wipe rag with gasoline on sticky stuff
|5| I have never had that not work but maybe it might no work in rare jars
|6| Dip in water and slother dish soap on and wash with hose
|7| Air dry outside or inside until smell gone (1 hour or what ever)

Jar is perfect clean and safe to use after air dry of solvent smell gone.

Simple summary is to soak label in water until label is easily removed and
then dissolve remaining glue on jar in gas and wash with dish soap to air
dry.

Yes everyone know stupid method of buying expensive lemon smell goop.
Every idiot know of goo gone pay through nose for great smell lousy work.

This different it is and is so not expensive that is almost free
(and is free to me because I use old gasoline from winter storage clean of
equipment)
