just be careful what you put in the washing machine, don't wanna damage the drum?! that said, I did put DS's runners in there today, in an old lingere bag
suppose it depends what toys you are washing
boiling hot water is a great way to clean things apparently as it kills bacteria (that's what I was told when learning to cook). But for example, I would normally swish my bath toys or plastic toys eg. little people with some vinegar. But if he had a cold sore I would do something more 'heavy duty' like pine o clean/domestos etc?
good luck- hope none appear, I have never had one so dunno how long it takes to appear or anything. I need to wash all our sufaces etc soon my kids and I have a yukky cold
