Why would you do that? You can wash them at 90 degrees (194 F) in the washing machine, which is pretty much the same as boiling in water. But 60 seems sufficient.

Of course lots of stuff wants to be washed at 40. 60 seems to be ok for cotton, but 90 is probably too much for most stuff. Also, some detergents may lose part of their effectiveness (enzymes) at high temperatures.
