Most producer and manufacturers are obliging and their labels are easy to remove leaving no residue and no frustrated jam maker. You simply soak in soapy water and peel off. But there are a few, and sods law says they are the ones which are an unusal shape and you really want, which have really stubbon labels that just will not shift. Or if they do they leave a white, glue residue. I’ve tried alcohol (for the label, not myself), soaking in soapy water over night, scraping with a knife – all without success. So How to remove labels from jars?
Then I tried baking powder – after all it worked shelling hazelnuts so why not? And it worked.
Score the label a few times to allow water to seep in.
Get a big pan, put in the jar(s), cover with boiling water and add 1 table spoon baking powder or bicarb. It will froth up like a vulcano so be warned – thus the big pan.
Leave to boil for around 5 mins.
Remove, test a corner. If it needs more then put it back.
Once ready remove and peel off as soon as it’s bareable to touch. Do not leave it to dry out otherwise you will have to begin again.
