Let me tell you about some of the differences between different methods for shampooing carpet.

Okay. I have several stains. Should I pretreat them?
user
Well, as a rule of thumb, most stains on carpet, especially the more darkly colored ones, can be pretty easily removed with a cleanser. You can use a commercial product, or you can just use some hot water with a detergent.  I do recommend that you use some vinegar if you can.  A bit of vinegar will break down some of the darker stains, and make them easier to clean.
