How do you brush a guinea pig?

What i do to bathe my guinea pig is to get a large bowl, a sink, or the bathtub and put about 5 or 6 inches of water in (maybe even less then that) Then put in one tiny squeeze of guinea pig shampoo just so there is tiny bubbles around the side of the tub you are using.Use a soft cloth or your hands to bathe your guinea pig. Hold your guinea pig to make it feel secure,it won't drown, and it won't run away. Then gently and thoroughly dry off your guinea pig when finished.
