My sister lives in Singapore, where the climate is hot but very humid. She's using Fuzzi Bunz on her 1 year old, but recently the microfibre inserts have begun to smell.
She line dries them, but not in the sun as she lives in an apartment block. She's tried boil washing them (just the inserts!) which helps for a couple of uses but then they start smelling again. She doesn't use too much detergent and has tried intensively rinsing them as well.
Can anyone advise please? I don't know if it is because they are just taking too long to dry, or if there is buildup of something.
