Do not scrub the carpet, as that will cause fraying. And do NOT put anything on it, as far as household cleaners go. The problem is the soapy residue from the shampoo--it must be treated the same way that you treat shampoo in your hair. It needs to be rinsed with plain water, extracted, rinsed, extracted, rinsed, extracted. The amount of times you have to do this will depend on how much shampoo was spilled. If you have a steam vac or a shop vac, either should work, as long as they have decent sucking power. If not, maybe you can borrow one. But again, it will just need to be rinsed using nothing but water, then sucked. Careful not to put too much water on it though--you don't want the water to seep down where you can't get it out.
