I've just bought a bundle of secondhand BGs and am washing them for the first time after using them. They are in a load with some other cloth nappies and some clothes etc so I've put in the usual amount of powder but just remembered that the BG website says to use half the amount What do I do about the other nappies in that case (I only have eight BG so will never be a full load)? Have I just destroyed my BG or will an extra rinse save them?
