If you have mixed the homemade dog food in your kitchen sink or a pan clean up is easy. I’ve found the best product I’ve found to clean up with is “Dawn” dish washing liquid. Dawn cuts the fat and is safe and very effective. Since the ingredients you are using are all human grade use the same practice you would use for cleaning up after you prepare a meal.
Admittedly, the ingredients in the advanced raw dog food recipe can be a bit gross and fall outside the “human grade” category. If you choose to feed the advanced raw dog food recipe you may want to prepare the food outside or somewhere that is easy to clean thoroughly.
