Concluding the "Get Rid Of" posts is a quick tip on how to remove the labels off glass or plastic jars.  

Covering the label with a wet paper towel and microwave the container on high for 2 minutes. Remember to take off any metal lids first! The label should just peel off.

The longer version is to fill up the sink with water and leave the jars to soak. I have fond memories of this as a child when my dad would soak wine bottles to keep the labels!
