Aldi have Sticky Stuff Remover on special offer this week.  Says on the label it removes labels, glue etc from glass amongst other substrates.

I have bought a bottle to see if it will clean the glue off jam jars, so they can be reused rather than recycled as a lost cause.

White sprit removes sticky label muck and much cheaper.

Nail varnish remover is also another good one.  Removed the sticky residue when the girls stuck their homemade decorations up on the windows one year with sellotape.

Yes, I have previously tried the white spirit and nail varnish remover route, with variable results.

I tested a very stubborn jar last night and after wrapping a rag wetted with the cleaner, the glue came off really easily.  Also it has a more pleasant smell than nail varnish remover.

wd40 is good for removing sticky stuff

My mum just soaks her jars in a tub of hot water and liquid soap for about 2 days and everything comes off nicely. I'm lazier and throw mine into the dishwasher. Soon as the cycle is finished I peel off the label and wipe off the sticky stuff. Anything else gets a bit of nail polish remover wiped over it.

i got sticky stuff remover from lakeland ages ago, probably not as cheap as Aldi but it's brilliant.
