While I’m On That What Science Tear . . .

walkitoutI talked to R. He doesn’t know why he did that either. He completely acknowledges that his experience making stock is at most 1/10th of mine and that he misremembered the temperatures. There were no raised voices or arguments. Hopefully, he’ll keep his thoughts to himself next time, or go double-check the numbers before messing with the temperature setting.
In the meantime, I remembered that whole tick thing from some years ago, and I got to wondering about what the status was on it.
In 2003, I found this:

In 2007, I find this:

These are likely sources of the hour on high heat in the dryer recommendation.
In 2013 — this is where I really sat up and took notice — a teen did a little science:

The teen came up with five minutes at low heat. Both the 2007 work and the 2013 work involved bugs in mesh bags. The 2007 work was high heat and no heat. The teen did a bunch of different temperatures.
Why is this important? No one is asking THAT question, because first of all, anyone who hikes knows what a nightmare this can be, and anyone who does laundry knows that you might as well just put your technical gear in the trash if you are going to have to put it in a dryer — dry already! — on high heat for an hour.
In 2016, we have this:
https://pubmed.ncbi.nlm.nih.gov/27156138/
4 minutes on high in the dryer — already dry — killed all the nymph and adult ticks.
I have been unable to find anyone checking for how long dry clothes and low heat requires to kill nymphs.

This one is really great. If you wash then dry, it takes longer, but if you _just dry_ and you use low heat, it’s 11 minutes to kill everything.
So, the teen wins! It’s a few minutes longer to get all of them, but low heat for a short period of time on dry clothes really does kill all the ticks.
I am particularly offended by the 6 minutes on high heat advice. While R. insists that as long as the jeans are dry going in, 6 minutes on high will not shrink them further. That does not match my recollection, but I don’t put anything in the dryer on high and I’m not about to start now. Most technical fabrics tell you to low heat or hang dry — the high heat setting in the dryer can absolutely affect the fit of anything containing spandex and modify the function of microfibers. (My husband has really damaged two of the special cloths I buy for makeup removal by putting in the dryer — on a fairly low heat setting! They really need to hang dry.)
When there is a slightly longer time frame on low heat that will work just as well, it’s fucking criminal to be giving such shitty advice. I don’t know what’s wrong with these people, altho just as a starting point, I’m going to assume they’re bad at laundry.
