@sinituulia@eldritch.cafe we wash everything at 40°C, everything hygiene-related (bedsheets, underwear, towels, etc.) at 60°C. I was despairing over "30°C gentle machine wash, no tumble dry, careful dry cleaning only" clothes just earlier today, too: 97% cotton, 3% elasthane chinos that were labelled as 30°C, no tumble drying, and loads of them in all sorts of colours, even "basically the natural colour of cotton" off-white.
I had half a mind to buy them, throw them in at 40°C and tumble dry, and see what comes out, but I couldn't afford sinking that money down the drain if it does damage them.

@amberage@eldritch.cafe Yeaaaaah, my bullshit senses are tingling with the "30C only" label on plant fibres at the best of times. At the very least it should take 40C without issue! There's no good reason why cotton (+elasthane) shouldn't withstand 60C! If they cut corners and didn't prewash and thus pre-shrink the fabric, it can shrink, but this really shouldn't be an issue.
I read somewhere that some percentage of human yeasts survive the 40C wash and may give you foot problems, so you should probably chuck socks into the hotter wash sometimes, too. 🤔
