Beocenter 9500 glass panel tape cleanup
in General Discussion & Questions · Jan 9, 2011 03:01I see that there has been mention on this site by another member of soaking the glass panel in warm soapy water and this then allows the old tape to be removed more easily. Anyone else tried this method? As you can tell,…
