hmm she swiped so still very sore.
Have you been given painkillers?
If you try to clean her up again later (when calm and sleepy is easiest isnt it?) do it really gently ... just the weight of the wet tissue is enough pressure and draw gently across the skin in little lapping motions... maybe try giving a head stroke at the same time and get a 2nd person to keep her focussed on the head/neck fuss (and treats if required) while you have a little clean up of her wound.
I think its better to get the wound cleaned up before it has set a hard scab because a neat clean scab just along the incision is better that a larger crusty scab that can be repeatedly rubbed or knocked off/open.
If your girl gets back to her usual inquisitive self quickly (before she has a dried and hardening wound site) and if she is the type to get into things and roll around on the floors ect try to confine her to one room to keep her wound as clean as possible..... once scabbed/dried out you can worry less about infections ect.
Spoil her rotten and tell us how is she in herself? is she glad to be home and pleased to be back with family?
/edit
afterthought, I remember I used kitchen towel not toilet tissue now because soft tissue can break up and will leave fibres behind that you dont want in the scab. dampened sterile bandage, kitchen tissue better than toilet tissue. You prolly figured this yourself
