Hi mummaajj, very exciting getting your first lot of fluffy mail
Well I rinse any poo then chuck into a dry bucket that's it.
Then I put them in the machine on a rinse cycle, then normal wash with either soap nuts or bi-carb and then dry in the sun. I think you can use the dryer I have maybe once to finish them off, but I think if you did it too often it might wear the elastic quicker?? The sun is fantastic for killing bacteria and bleaching stains
