This is what the bottles look like after I took the labels off, very sticky and part of the old labels still tightly affixed to the bottles.
I squirted some of the Best Cleaner ever (http://scraperfect.com/best-cleaner-ever-3/) and then rubbed off the old label and glue. It took 2 squirts but everything came off with very little effort. In the past I would have used Goo Be Gone but it would have taken more effort and more squirts to get everything off.
My cleaned bottles already to be filled.
If you haven't tried out this Best Cleaner Ever (http://scraperfect.com/best-cleaner-ever-3/) you really need to give it a try.
