Commercially lye dissolved in tetra hydro furan is used to remove cured
rubber. this is extremely nasty stuff and will probably dissolve the plastic
frame. I have personally disassembled tanks for repair by dragging a double
razor blade through the seam with a pair of vise grip pliers. I then used a
blade scraper to remove all of the silicon rubber from the glass so that the
could be reassembled. This is important since the silicon rubber does not
well to itself. >>
Be very careful with THF, we used many gallons of this solvent in "welding"
vinyl liner sheeting together for water-effects underliners over the years.
VERY flammable, and not good to inhale fumes of either (maybe that's why I
can't get out of the pet-fish biz?). The SOP in the trade is new single edge
razor blades to split seams, and a solvent (toluene, xylene, others... with
gloves, good ventilation) used to clean used panels of old silicone residue
(and gunk from fingers, etc.).
