I,'m not familiar with that product and would look up the product data sheet if there is anyting mentioned about getting it on skin.
i think wiping them with a wet towel would imo best if it's rather harmless stuff. Do not bath them unless necessary, getting a soaked rabbit dry again is a real chore. If it needs to be done, only get the necessary areas wet, like putting their rear in a shallow container. Put something on the bottom so they have some grip, makes things easier.
