Clothes that have labels saying wash at 30 - is it because you can get machines that do 30 now and they're encouraging you to be greener? Or is it because the dye will run like mad if you wash at 40? Our machine is quite old and doesn't do anything less than 40, so I handwash all the stuff that says 30 (including baby clothes ).
Would it just be better to get a new machine?! The one we have was in the house when we moved in 6 years ago so goodness knows how long it had been there before then. I suppose it's green not to replace it, but then if it's using more energy than it needs to... ???
