Revive Old Caulk Tubes
Nancy Hart Serum of Oakland, California writes:
In my experience, it doesn’t matter if I insert a nail or a screw into the nozzle of a partially used tube of caulk. The caulk will still coagulate into a frustrating lump that renders the tube useless. To remove the hardened caulk, I use my utility knife to slit the entire length of the nozzle. Then I pry out the caulk lump, andtape the nozzle back together with electrician’s tape.
