Heat drying is a topic that is often discussed with almost a cult style narrative that usually alarms my critical reader mind instantly and I move on since it seems to scream sales ad disguised as technical info.
I have been a restorer since before the E-ties fad and before the Thermapure lawsuit, which seemed to take the industry through a bipolar phase of “it’s the only way to dry” to “don’t use it, you will be sued out of existence”, which is a pretty long stretch on either side.
