I concur. I’m going to give this “FixDry” a try. It claims it can do 70C for up to 48 hours. I’ve loaded it in, and “we’ll see.”
This will be the first time I’ve tried using it. It’s one of the cheaper brands, so I don’t have high hopes for it, but nothing ventured nothing gained. Looking at the build quality, my first impression is that it may actually be adequate for the task. After all, it’s basically just a feeble fan blowing over a heating element controlled by a thermostat, so not exactly rocket surgery.
