Hi Tr186, well to tell you the truth I`ve never been asked to clean carpet in a boat. I clean my carpet with a garden hose with no soap. The soap will get down in th carpet and stay there and the next time your in a pouring rain here comes the suds, plus the soap just holds the dirt and it gets dirtier faster. The nap-fibers now adays are very stain proof and a good hard clean water will wash the dirt out. If you do have a stain use some Resolve or Spot shot and let it work for a minute or 2 and don`t rub it off,,,,,take a towel or paper towels and wick it up,,,then raince. I was a carpet installer for 30yrs(got out of that thank God) and thats how we removed stains. If your nap don`t stand back up use a good vac on it and that will help strighten the fiber up.
