From a skim it looks like the highest setting tested was 60°C which can kill, but wouldn't be considered sufficient in all cases for food safety for example.
My own washing machine is nothing special (front-loader Euromaid, whatever was cheap ~10 years ago) and you can manually bump to temperature up to 70/80/90°C for a cycle (which adds some time). I haven't measured it though to see how accurate it is and I'd imagine 90°C at least isn't great for those rubbery painted patterns or general clothing integrity either.
I started using the higher temperatures occasionally since I have some old t-shirts, but I always have to stop wearing them since the underarms develop a crust - I guess it's some kind of bio-reaction between me, my bacteria ride hitchers, and deodorant. Higher temps do seem to delay this build-up (which seems impossible to clean off), but does seem to reduce the life expectancy of the clothing. When I see people (mostly women) still wearing shirts they got in high school, it makes me a little envious. Mine got that issue in < 5 years before changing the wash temps :(
