Reusing plant labels.
I bought tags from Lowe's the past few years. They all have writing on at least one side many both sides. I came up with a crazy idea to soak a bunch in bleach water over the winter to see if they would clean up. After a few weeks I kept looking at the container thinking this is futile. The writing was still there and dark. I just left them there all winter.
Today I was taking them out to actually spray paint them white as I have done to a few others as a test (which also works). Seeing as I could still see writing on the tags in the bottle. Well while rinsing the bleach water off the writing came off, I was upset at first cause some of it was still there, mainly the paint marker, but with a single gentle swipe it was gone. The Sharpie ink came off much easier than the paint marker, I very much suggest getting paint markers for labels. It will not fade. (Well unless you soak them in strong bleach for several month's.)
A VERY VERY faint reminder is on a few of them but all in all they look brand new.
Score one of recycling.
