First things first, mix 4 c hydrogen peroxide with 4 tbsp baking soda and 1 tsp dish-washing soap.
Make sure that you are wearing rubber gloves throughout this process. You need to protect your hands from not only the scent but also from the chemicals being used in the mixture.
Carry out this process outdoors since you will probably be creating a lot of mess.
In order to protect the inner ear tissue of your pet from the cleaning mixture, use cotton balls. Simply put them inside your pet’s ears and make sure that the mixture does not drip into his/her ears at all.
Start off from your pet’s head. This is because you need to be extra careful throughout the process of the head. You need to protect his/her eyes, nose and mouth. You already used cotton balls to protect his/her ears, now make sure that you protect his/her eyes. In order to do that, put baby oil around his/her eyes as it is going to protect him/her from irritation. Start washing his/her head slowly and carefully.
Start rubbing the mixture on your pet’s coat. He/she will most probably be trying to get rid of it, but keep rubbing it. Make a good lather around the coat and use a brush if there is a lot of fur on it.
Rinse the coat with clean water and make sure you scrub everything out. If the mixture remains in your pet’s fur, it will create a thick surface on top of his/her skin.
If the smell still persists, then repeat all steps.
