A while ago I did a post on easily removing goo with peanut butter.
This is still my tried and true method
but the other day I found another easy trick.
Put your chosen jar through the dishwasher.
When the dishwasher has just finished and the jar is still hot
use steel wool and scrub the label right off.
This only works while the jar is still hot.
Great idea!! I have also had great luck removing labels by pouring boiling water in the jar and letting it sit and get the jar hot for a couple of minutes, then it often peels right off. 🙂
