Dawn® Dish Soap
Many times when dealing with a particularly dirty or greasy coat, groomers reach for the Dawn® dish soap to help clean and degrease the animal. You need to use a conditioner after a strong degreaser in order to protect the hair and help lubricate the skin, but Dawn® is considered safe to use on occasion — after all, it's used on wildlife after oil spills.
You can also kill fleas with dish soap. If your dog or cat has fleas, rub Dawn® diluted with water on dry hair; let it sit for ten minutes, then rinse. The fleas will be dead or will drown when you rinse them.
20 Mule Team Borax® is a product used for whitening clothes, but it also works well to kill fleas in carpeting. Sprinkle it liberally onto your carpet, work it in with a broom, let it sit overnight, then vacuum. Another plus — it smells nice! You can find it in the laundry aisle at the market.
A dab of dish soap on a tick will cause it to detach from its host within a few seconds. You can put dish soap directly on the tick or on a cotton ball and hold it on the tick for a few seconds. Either way, the tick will detach.
