cleaning box for new babies

Question
We have six new babies about 2 weeks old.  They look healthy but they smell bad and have pee on them.  They are in a wood box in their mothers hair.  I am wondering how I can keep them cleaner without harming or upsetting them.  They are in a well built hutch outside in cooler wheather with fall arriving.
We have pollyurithane which feels allot like the mothers fur but I don't want to do anything until I am sure it is safe.
Thank you very much for your help.

Hi Maria,

What you can do is get rid of the soiled bedding, clean the bottom of the box (vinegar), and replace it with soft, clean, old cotton tshirts, and make a "well" in the middle of the tshirts that you can place the babies back into.  If their bottoms are messy you can use a baby wipe and wipe their bottoms.

Try making sure you have a couple of sets of clean tshirts so that after a day or two, you can swap out the used tshirts and quickly replace them with the new, clean tshirts.
