I just looked it up. A dryer can get up to 190*.
If we only need 104* to kill the bugs (BS! That’s not ‘hot’. That is warm! If 104* is hot enough to kill bugs, then I’m perfectly sterilized every time I take a shower.) then 190* will finish off anything the washer doesn’t catch.
These are people looking for a problem that doesn’t exist.
Unless you line-dry. Then I could see germs getting pushed around and the clothes not being really ‘clean’.
I have one of those big top loaders without an agitator. It does all right, but I LOVE the built in water heater. I use it a lot. Towels never stink anymore, I know undies, socks, and linens are clean. It doesn’t fill up like a traditional top loader, so this is important to me. It took a while to get it figured out.
Happy washing!
