First post but have been lurking for a wee while. So just been told that my DD has a house dust mite allergy. First thing I do is Google to see what I can do to help and find info about hypoallergenic pillows and duvet (no problem with that) then everything I read says to damp dust. I've never heard of this! I can't imagine that a yellow duster will be much use damp so what do I use?? And does it just mean damp with water or is there some magic cleaning formula that I'm missing too??? Surely I should have heard of this before now!!! Any help from the more house proud/better informed would be very welcome!!!
