It may not be the most thrilling conversation topic but if you have small kids or teach baby massage then you probably get through alot of towels.
I find that an average baby massage class gets though around about 30 towels. I’ve got a 9kg front load washing machine and 30 towels is about its limit.
I use and Eco Egg and Miofresh to wash my towels. My eldest daughter has very sensitive skin and we found that most detergents had a bit of perfume in or left residues on the laundry but the Eco Egg washes in a different way so nothing is left on the clothes or towels to irritate skin.
I add the Mio Fresh to ensure that there are no germs left on the towels. Having used cloth nappies with my children i’m quite familiar with getting baby solids and liquids out of fabrics and this combo is what works for me.
