Where can I get replacement Probes for these thermometers: Oregon Scientific thermometer model # 129 (I believe that the Polder 365 worksâ€¦Does anyone knows if this is so?) Charmglow model # ET-71 â€¦.Clone of the Maverick ET-71 Iâ€™ve herd that probes can be boiled in oil to â€œrestoreâ€ themâ€¦does anyone know if this works. If so, heat oil to what temperature, for how long do I â€˜boilâ€™ probe etc? Iâ€™ve also herd that heat shrink tube placed over the joint between the probe & wire braid will protect the probeâ€¦.is this so? Thanks in advance for your kind help.
