I scotchguard my crapet every spring with the green "outdoor" scotchguard. It works great. I have spilled alot of coffee on my boat, it will just sit on top of the carpet and you can soak it up with a rag. Cleans up like it was never there, no need to go back over it with soap or spot remover. The one downside to the scotchguard, is that it makes your carpet veeery slippery, not to walk on, but for items you leave laying around. Gotta make sure to secure things down when you open up the motor, especially the trolling motor pedal.
