Product review (3 stars): Pink color makes wick look like it has "pink mold'
This product works well and extends the life of the wicks, but the pink color is a problem.  I have trouble with "Pink Mold," (which is actually Staph bacteria that can cause respiratory infections).  I add treatment to prevent the pink mold, but with the pink color staining the wicks it looks very much like the pink mold which would grow without the treatment!  As others have stated the pink color can also be difficult to remove if you spill even a drop of it (I have white counter tops which really show the color).  I don't know if the pink is an added dye or an active ingredient, but other colorless products seem to work just as well.
