Labels are not scraping off from your jars! NOTHING at all! Desperate to find a way. Lol! (this reads like a commercial).
Adhesive works like this. The glue used by jars, loves the jar because essentially the chemical is sticky/adhesive, and those atoms loves to this bonding-act. So, what do we need. We need anything that makes them repel each other. A list of 3 repellents:
1. Hot water.
3. Scrapping stuff. Scrapper, salt, butter or a nail filer.
Just try it. Don't want to keep ranting about how good the above three can work for you. Lots of tips for scrapping off labels are given here: thriftyfun.com
